“Even more progress” sums up this latest Cloud Foundation on VxRail release—more progress in LCM enhancements, more progress with new hardware platform options, and more progress toward driving a simpler cloud operations experience for VCF on VxRail customers. This new release is based on the latest software bill of materials (BOM) featuring vSphere 8.0 U3, vCenter 8.0 U3a, vSAN 8.0 U3, and NSX 4.2.0. Read on for more on the new hardware platforms, significant lifecycle management enhancements, and networking & security updates in this release. 

Hardware platform updates

The latest release brings forth support for new VxRail hardware platforms and enhancements to existing ones. The AMD-based VxRail 16G VE-6615 and VP-7625 hardware platforms are among the newly introduced platforms, featuring the powerful AMD EPYC Gen 4 processor. The VE-6615, a compact 1U platform, is tailored for general-purpose workloads, while the VP-7625, a scalable 2U platform, is designed for optimized performance. Additionally, the release includes the introduction of the Intel®-based storage-optimized platform VS-760.

Furthermore, VCF 5.2 on VxRail 8.0.300 unveils the much-anticipated support for the VD-4000 hardware platform. The VD-4000 offers a cutting-edge VxRail node option specifically crafted for edge use cases. This ruggedized platform features a purpose-built smaller form factor, extending the advantages of VxRail to previously inaccessible locations due to challenging conditions, limited bandwidth, and space constraints. Supported in 3+ node cluster configurations within the workload domain, the VD-4000 integrates seamlessly with both vSAN OSA and ESA, providing a robust edge computing solution.

LCM updates

VCF 5.2 introduces several lifecycle management enhancements. It offers more flexible updates, better scale for operations, and faster deployment and patching.

Notably, all upgrade and patch bundles are now conveniently accessible within the SDDC Manager interface, eliminating the necessity for manual patching via the CLI. Moreover, patches can now be seamlessly applied during upgrade workflows, and newly deployed workload domains and clusters deploy with the latest patches already applied, streamlining administrative tasks and reducing operational overhead.

Let’s expand on these enhancements in more detail.

Skip-level upgrade

The skip-level upgrade feature enables customers running older versions of VCF to transition directly to the latest VCF 5.x release, bypassing intermediate VCF versions. Users on version VCF 4.5.1 and above can seamlessly upgrade to the VCF 5.2 release without migrating workloads or hardware swaps. This streamlined upgrade process simplifies the transition to the latest VCF version, enhancing operational efficiency and minimizing disruptions.

VCF upgrade flexibility

In VCF 5.2, the upgrade process for a workload domain now offers the flexibility to customize the Bill of Materials (BOM) to accommodate any newly released asynchronous patches. This enhancement streamlines the upgrade workflow, as only one single run is needed to align the domain with the preferred component versions. Previously, users had to conduct the upgrade and subsequently apply async patches separately. Workload domains can now feature distinct combinations of component versions tailored to specific workload requirements, with SDDC Manager conducting compatibility validations to verify that the customized BOM remains within supported configurations.

Independently upgrade SDDC Manager

With the introduction of VCF 5.2, customers now have the option to incrementally upgrade the SDDC Manager component independently over time without updating the remaining infrastructure components within the management domain. This approach facilitates quicker adoption of new functionalities and fixes without necessitating extensive updates to NSX, vCenter Server, and ESXi hosts.

Patch individual VCF on VxRail components using SDDC Manager

After a particular VCF BOM has been released, updating one or more of the individual components may be necessary to address reliability or security issues. These individual component updates (referred to as "async patches") are delivered separately from the VCF release BOM. Previously, customers looking to update their workload domains had to utilize the Async Patch Tool, a separate command-line interface utility. However, with VCF 5.2, the deployment of async patches can now be seamlessly applied within the familiar SDDC Manager UI. Users can conveniently select from available patches in a dropdown menu, which dynamically updates as the SDDC Manager receives the latest bundle data from online repositories or offline sources.

Built-in Inventory Version Synchronization

This feature is related to patching individual VCF on VxRail components using SDDC Manager. When applying async patches, it’s crucial to follow specific instructions for updating the VCF inventory using the Async Patch Tool’s sync command. Lack of synchronization could cause issues during upgrades. Before VCF 5.2, users had to manually sync the inventory using the CLI and the Async Patch Tool. Now, with VCF 5.2, there’s an automatic mechanism to make this process easier and improve the user experience.

Create an Offline Depot local patch repository

In scenarios where VCF deployments are unable to connect to the Internet's online depot due to technical constraints or policy restrictions (referred to as "dark sites"), the downloading of essential software bundles for infrastructure updates and deployments becomes challenging. To address this limitation, customers traditionally relied on the Offline Bundle Transfer Utility (OBTU) CLI tool to download bundles to a separate system and then transfer and import them into SDDC Manager to then perform LCM operations. This method would need to be repeated, potentially requiring separate downloaded copies of update bundles and bundle transfers for each VCF instance deployed within a customer environment.

However, with the introduction of VCF 5.2, a new configuration option within SDDC Manager offers a solution by allowing downloads from a local web server instead of the online depot. This local server, referred to as an "offline depot," involves the utilization of a customer-managed web server equipped with an enhanced version of OBTU. This approach effectively establishes a local mirror of the online depot, enabling seamless centralized access to single copies of necessary software bundles within dark site environments.

Deploy new async patched domains

In the past, every new workload domain and cluster was deployed with component versions matching those of the management domain BOM. Subsequently, async patches had to be manually applied to each new domain after deployment.

With the introduction of VCF 5.2, administrators can deploy new domains and clusters that match the patch levels implemented in the management domain. This advancement eliminates the need to patch a newly deployed domain, enhancing operational efficiency and scalability.

Independent TKG Service

In VMware Cloud Foundation 5.2, the TKG Service in vSphere 8.0 U3 has been decoupled from vCenter Server, allowing it to be implemented independently as a core Supervisor Service. This architectural change empowers Administrators to introduce asynchronous updates to the service, ensuring alignment with upstream Kubernetes and facilitating the rapid delivery of new Kubernetes versions. This decoupling enhances agility and enables faster adoption of Kubernetes advancements within the VMware ecosystem.

Networking updates

Configure an Isolated Domain with a Shared NSX instance

In previous VMware Cloud Foundation versions, each individual Isolated Workload Domain required a dedicated NSX instance. However, with the introduction of VCF 5.2, Administrators now have the flexibility to configure multiple isolated domains utilizing a shared NSX instance. Each isolated workload domain utilizing a shared NSX instance is independently set up with its own SSO instance and Identity Provider.

Utilizing a shared NSX instance across domains offers the advantage of a unified management interface through the NSX Manager console for all NSX network components within a given topology. Additionally, a single transport zone is shared across all clusters present in either all VI workload domains or all isolated workload domains linked to the shared NSX Manager instance. This shared NSX instance also reduces the number of NSX controllers needed to manage the NSX environment effectively.

To learn more, please check the following demo of this feature:

TEP performance enhancements with NSX Edges

In scenarios where NSX Edges handle traffic across multiple TEPs per NSX segment, in many cases, a single segment is involved when routing traffic through an Edge, leading to the utilization of a single TEP. Customers with significant throughput demands have observed limitations in the processing capacity of individual edges under such circumstances. To address this challenge and enhance traffic handling capabilities, implementing a more granular per-flow load sharing mechanism across the Edge TEPs is recommended and now possible.

NSX Advanced Load Balancer integration with SDDC Manager

VCF 5.2 now integrates with the NSX Advanced load balancer (formerly AVI). This integration allows VCF Administrators to leverage the SDDC Manager to deploy an NSX Advanced Load Balancer controller cluster within deployed workload domains. It's important to highlight that utilizing the NSX Advanced Load Balancer requires an add-on license. This integration streamlines the deployment of the AVI Load Balancer Controller Cluster. The AVI controller configuration and Service Engines' deployment are managed through the AVI Admin Console.

Storage updates

Protect and recover VMs against accidental and malicious activities

vSAN 8 U3 leverages the robust snapshotting capabilities of ESA to enhance data protection and operational flexibility. With the Data Protection for vSAN ESA, VCF administrators now have the capability to safeguard and restore VMs in the event of accidental deletions or malicious activities like ransomware attacks. This functionality simplifies the setup by enabling the configuration of protection groups to specify which VMs require protection, the frequency of snapshots, and the retention period. Moreover, the option to make snapshots immutable provides an additional layer of defense, particularly for scenarios requiring robust ransomware protection. Furthermore, seamless integration with VMware Live Cyber Recovery (VLCR) enhances the overall ransomware protection strategy by offering comprehensive cloud-based solutions.

Support for vSAN Witness Traffic Separation (WTS) as a VCF on VxRail standard feature

VCF on VxRail now supports vSAN Witness Traffic Separation (WTS) configurations as a standard feature, eliminating the need to pursue Dell exception support. The VMware and Dell Technologies documentation will be revised to align with this updated standard feature.

Security updates

Identity Federation Support with Microsoft Entra ID

VMware Cloud Foundation offers support for Identity Federation through various third-party providers. The VMware Identity Service allows configuration for federation utilizing Okta and Microsoft Entra ID (introduced in VCF 5.2) with plans for additional third-party identity providers in upcoming releases. When users initiate login requests to VCF, these requests are directed to the chosen authentication service. Following authentication validation based on specified criteria, the third-party authentication service provides an access token/claim for the user's login request, enabling VCF to authorize access to its dashboards. Authenticated users can seamlessly navigate between SDDC Manager, vCenter Server, and NSX Manager, enhancing operational efficiency and user experience within the VCF environment.

Configure a Proxy Server with Authentication

In previous releases of VMware Cloud Foundation, the capability to set up a proxy server within SDDC Manager was available but lacked the option to configure authentication. The latest version of VCF now enables administrators to configure a proxy server with authentication for the download and installation of update bundles. The SDDC Manager interface can be used to establish proxy server authentication, supporting basic or NTML authentication methods. Additionally, if your proxy server operates on secure HTTPS protocols, the SDDC Manager now includes support for configuring this flexible security protocol level.

SDDC Manager Compliance APIs

New SDDC Manager compliance APIs have been introduced. While current support is limited to PCI compliance, VMware intends to expand this support to include additional compliance standards in upcoming releases. This enhancement enables users and third-party reporting software to programmatically access configuration audit results for SDDC Manager, facilitating streamlined compliance monitoring and reporting processes.

Operations and serviceability user experience updates

Aria Operations enhancements

The Aria Operations console in VMware Cloud Foundation (VCF) offers a centralized interface for managing the VCF stack, streamlining application and infrastructure management. It serves as a control plane for global inventory, lifecycle operations, and administrative tasks, enhancing operational efficiency. Integrating diagnostic functionalities from Skyline Health Diagnostics and Skyline Advisor into Aria Operations provides administrators with a unified platform to identify issues, access automated recommendations, and ensure efficient troubleshooting. Additionally, the console simplifies license key management and enhances certificate visibility, allowing IT admins to monitor certificate health, receive expiration alerts, and generate compliance reports for audit purposes.

Aria Automation enhancements

The enhanced VCF integration with Aria Suite boosts cloud resource visibility and streamlines cloud setup with Quick Start workflows. The Dashboard and Launchpad on the Home Page simplify access to crucial information. Through guided workflows, users can efficiently establish cloud services, create cloud accounts, and align resources with business needs. Admins can customize Supervisor Namespace classes for self-service provisioning, allowing developers to deploy workloads quickly via the Cloud Consumption Interface or curated catalog items. Governance is ensured through policies like leasing and approvals as well as maintaining operational compliance and control.

HCX Updates

HCX 4.10 enhances performance and scalability and is fully compatible with VCF 5.2. Migration capacity increased from 600 to 1,000 VMs, optimizing efficiency and reducing costs. HCX Assisted vMotion (HAV) accelerates Cross vCenter vMotion for faster migration times. Enhanced encryption options are introduced for migration and network extension services. Finally, OS-Assisted Migration deployment is streamlined, reducing solution footprint.

VCF Private AI Foundation updates

New VMware Private AI Foundation with NVIDIA Aria Automation catalog options

The VMware Private AI Foundation with NVIDIA was initially introduced as a post-GA feature in version 5.1.1, however it has been validated and officially supported in VCF on VxRail. Within VMware Aria Automation—a part of the solution—users can access expanded catalog items, including AI Workstation, AI RAG Workstation, and Triton Inferencing Server. These new catalog items empower users to provision TKG clusters and leverage vGPU and RAG operators for deploying AI RAG applications on the TKG cluster. Additionally, Deep Learning VM catalog items now support the execution of custom cloud-init configurations for better customization.

Summary

The latest release is packed with new features, including support for multiple new hardware platforms, notable lifecycle management enhancements, networking and security updates, and substantial improvements in integration with Aria Suite.

HCI networking made easy (again!). Now even more powerful with multi-rack support.

The Challenge

Network infrastructure is a critical component of HCI. In contrast to legacy 3-tier architectures, which typically have a dedicated storage and storage network, HCI architecture is more integrated and simplified. Its design allows you to share the same network infrastructure used for workload-related traffic and inter-cluster communication with the software-defined storage. Reliability and the proper setup of this network infrastructure not only determines the accessibility of the running workloads (from the external network), it also determines the performance and availability of the storage, and as a result, the whole HCI system.

Unfortunately, in most cases, setting up this critical component properly is complex and error-prone. Why? Because of the disconnect between the responsible teams. Typically configuring a physical network requires expert network knowledge which is quite rare among HCI admins. The reverse is also true: network admins typically have a limited knowledge of HCI systems, because this is not their area of expertise and responsibility.

The situation gets even more challenging when you think about increasingly complex deployments, when you go beyond just a pair of ToR switches and beyond a single-rack system. This scenario is becoming more common, as HCI is becoming a mainstream architecture within the data center, thanks to its maturity, simplicity, and being recognized as a perfect infrastructure foundation for the digital transformation and VDI/End User Computing (EUC) initiatives. You need much more computing power and storage capacity to handle increased workload requirements.

At the same time, with the broader adoption of HCI, customers are looking for ways to connect their existing infrastructure to the same fabric, in order to simplify the migration process to the new architecture or to leverage dedicated external NAS systems, such as Isilon, to store files and application or user data.

A brief history of SmartFabric Services for VxRail

Here at Dell Technologies we recognize these challenges. That’s why we introduced SmartFabric Services (SFS) for VxRail. SFS for VxRail is built into Dell EMC Networking SmartFabric OS10 Enterprise Edition software that is built into the Dell EMC PowerSwitch networking switches portfolio. We announced the first version of SFS for VxRail at VMworld 2018. With this functionality, customers can quickly and easily deploy and automate data center fabrics for VxRail, while at the same time reduce risk of misconfiguration.

Since that time, Dell has expanded the capabilities of SFS for VxRail. The initial release of SFS for VxRail allowed VxRail to fully configure the switch fabric to support the VxRail cluster (as part of the VxRail 4.7.0 release back in Dec 2018). The following release included automated discovery of nodes added to a VxRail cluster (as part of VxRail 4.7.100 in Jan 2019).

The new solution

This week we are excited to introduce a major new release of SFS for VxRail as a part of Dell EMC SmartFabric OS 10.5.0.5 and VxRail 4.7.410.

So, what are the main enhancements?

• Automation at scale
   Customers can easily scale their VxRail deployments, starting with a single rack with two ToR leaf switches, and expand to multi-rack, multi-cluster VxRail deployments with up to 20 switches in a leaf-spine network architecture at a single site. SFS now automates over 99% (!) of the network configuration steps^* for leaf and spine fabrics across multiple racks, significantly simplifying complex multi-rack deployments.
• Improved usability
   An updated version of the OpenManage Network Integration (OMNI) plugin provides a single pane for “day 2” fabric management and operations through vCenter (the main management interface used by VxRail and vSphere admins), and a new embedded SFS UI simplifying “day 1” setup of the fabric.
• Greater expandability
   Customers can now connect non-VxRail devices, such as additional PowerEdge servers or NAS systems, to the same fabric. The onboarding can be performed as a “day 2” operation from the OMNI plugin. In this way, customers can reduce the cost of additional switching infrastructure when building more sophisticated solutions with VxRail.

Figure 1. Comparison of a multi-rack VxRail deployment, without and with SFS

Solution components

In order to take advantage of this solution, you need the following components:

• At a minimum a pair of supported Dell EMC PowerSwitch Data Center Switches. For an up-to-date list of supported hardware and software components, please consult the latest VxRail Support Matrix. At the time of writing this post, the following models are supported: S4100 (10GbE) and S5200 (25GbE) series for the leaf and Z9200 series or S5232 for the spine layer. To learn more about the Dell EMC PowerSwitch product portfolio, please visit the PowerSwitch website.
• Dell EMC Networking SmartFabric OS10 Enterprise Edition (version 10.5.0.5 or later). This operating system is available for the Dell EMC PowerSwitch Data Center Switches, and implements SFS functionality. To learn more, please visit the OS10 website.
• A VxRail cluster consisting of 10GbE or 25GbE nodes, with software version 4.7.410 or later.
• OpenManage Network Integration (OMNI) for VMware vCenter version 1.2.30 or later.

How does the multi-rack feature work?

The multi-rack feature is done through the use of the Hardware VTEP functionality in Dell EMC PowerSwitches and the automated creation of a VxLAN tunnel network across the switch fabric in multiple racks.

VxLAN (Virtual Extensible Local Area Network) is an overlay technology that allows you to extend a Layer 2 “overlay” network over a Layer 3 (L3) “underlay” network by adding a VxLAN header to the original Ethernet frame and encapsulating it. This encapsulation occurs by adding a VxLAN header to the original Layer 2 (L2) Ethernet frame, and placing it into an IP/UDP packet to be transported across the L3 underlay network.

By default, all VxRail networks are configured as L2. With the configuration of this VxLAN tunnel, the L2 network is “stretched” across multiple racks with VxRail nodes. This allows for the scalability of L3 networks with the VM mobility benefits of an L2 network. For example, the nodes in a VxRail cluster can reside on any rack within the SmartFabric network, and VMs can be migrated within the same VxRail cluster to any other node without manual network configuration.

Figure 2. Overview of the VLAN and VxLAN VxRail traffic with SFS for multi-rack VxRail

This new functionality is enabled by the new L3 Fabric personality, available as of OS 10.5.0.5, that automates configuration of a leaf-spine fabric in a single-rack or multi-rack fabric and supports both L2 and L3 upstream connectivity. What is this fabric personality? SFS personality is a setting that enables the functionality and supported configuration of the switch fabric.

To see how simple it is to configure the fabric and to deploy a VxRail multi-rack cluster with SFS, please see the following demo: Dell EMC Networking SFS Deployment with VxRail - L3 Uplinks.

Single pane for management and “day 2” operations

SFS not only automates the initial deployment (“day 1” fabric setup), but greatly simplifies the ongoing management and operations on the fabric. This is done in a familiar interface for VxRail / vSphere admins – vCenter, through the OMNI plugin, distributed as a virtual appliance.

It’s powerful! From this “VMware admin-friendly” interface you can:

• Add a SmartFabric instance to be managed (OMNI supports multiple fabrics to be managed from the same vCenter / OMNI plugin).
• Get visibility into the configured fabric – domain, fabric nodes, rack, switches, and so on.
• Visualize the fabric and the configured connections between the fabric elements with a “live” diagram that allows “drill-down” to get more specific information (Figure 3).
• Manage breakout ports and jump ports, as well as on-board additional servers or non-VxRail devices.
• Configure L2 or L3 fabric uplinks, allowing more flexibility and support of multiple fabric topologies.
• Create, edit, and delete VxLAN and VLAN-based networks, to customize the network setup for specific business needs.
• Create a host-centric network inventory that provides a clear mapping between configured virtual and physical components (interfaces, switches, networks, and VMs). For instance, you can inspect virtual and physical network configuration from the same host monitoring view in vCenter (Figure 4). This is extremely useful for troubleshooting potential network connectivity issues.
• Upgrade SmartFabric OS on the physical switches in the fabric and replace a switch that simplifies the lifecycle management of the fabric.

Figure 3. Sample view from the OMNI vCenter plugin showing a fabric topology

To see how simple it is to deploy the OMNI plugin and to get familiar with some of the options available from its interface, please see the following demo: Dell EMC OpenManage Network Integration for VMware vCenter.

OMNI also monitors the VMware virtual networks for changes (such as to portgroups in vSS and vDS VMware virtual switches) and as necessary, reconfigures the underlying physical fabric.

Figure 4. OMNI – monitor virtual and physical network configuration from a single view

Thanks to OMNI, managing the physical network for VxRail becomes much simpler, less error-prone, and can be done by the VxRail admin directly from a familiar management interface, without having to log into the console of the physical switches that are part of the fabric.

Supported topologies

This new SFS release is very flexible and supports multiple fabric topologies. Due to the limited size of this post, I will only list them by name:

• Single-Rack – just a pair of leaf switches in a single rack, supports both L2 and L3 upstream connectivity / uplinks – the equivalent of the previous SFS functionality
• (New) Single-Rack to Multi-Rack – starts with a pair of switches, expands to multi-rack by adding spine switches and additional racks with leaf switches
• (New) Multi-Rack with Leaf Border – adds upstream connectivity via the pair of leaf switches; this supports both L2 or L3 uplinks
• (New) Multi-Rack with Spine Border - adds upstream connectivity via the pair of leaf spine; this supports L3 uplinks
• (New) Multi-Rack with Dedicated Leaf Border - adds upstream connectivity via the dedicated pair of border switches above the spine layer; this supports L3 uplinks

For detailed information on these topologies, please consult Dell EMC VxRail with SmartFabric Network Services Planning and Preparation Guide.

Note, that SFS for VxRail does not currently support NSX-T and VCF on VxRail.

Final thoughts

This latest version of SmartFabric Services for VxRail takes HCI network automation to the next level and solves now much bigger network complexity problem in a multi-rack environment, compared to much simpler, single-rack, dual switch configuration. With SFS, customers can:

• Reduce the CAPEX and OPEX related to HCI network infrastructure, thanks to automation (reducing over 99% of required configuration steps^* when setting up a multi-rack fabric), and a reduced infrastructure footprint
• Accelerate the deployment of essential IT infrastructure for their business initiatives
• Reduce the risk related to the error-prone configuration of complex multi-rack, multi-cluster HCI deployments
• Increase the availability and performance of hosted applications
• Use a familiar management console (vSphere Client / vCenter) to drive additional automation of day 2 operations
• Rapidly perform any necessary changes to the physical network, in an automated way, without requiring highly-skilled network personnel

Preserving data integrity in case of unplanned power events

The challenge

Over the last few years, VxRail has evolved significantly -- becoming an ideal platform for most use cases and applications, spanning the core data center, edge locations, and the cloud. With its simplicity, scalability, and flexibility, it’s a great foundation for customers’ digital transformation initiatives, as well as high value and more demanding workloads, such as SAP HANA.

Running more business-critical workloads requires following best practices regarding data protection and availability. Dell Technologies specializes in data protection solutions and offers a portfolio of products that can fulfill even the most demanding RPO/RTO requirements from our customers. However, we are probably not giving enough attention to the other area related to this topic: protection against power disturbances and outages. Uninterruptible Power Supply (UPS) systems are at the heart of a data center’s electrical systems, and because VxRail is running critical workloads, it is a best practice to leverage a UPS to protect them and to ensure data integrity in case of unplanned power events. I want to highlight a solution from one of our partners – Eaton.

The solution

Eaton is an Advantage member of the Dell EMC Technology Connect Partner Program and the first UPS vendor who integrated their solution with VxRail. Eaton’s solution is a great example of how Dell Technologies partners can leverage VxRail APIs to provide additional value for our joint customers. Having integrated  Eaton’s Intelligent Power Manager (IPM) software with VxRail APIs, and leveraged Eaton’s Gigabit Network Card, the solution can run on the same protected VxRail cluster. This removes the need for additional external compute infrastructure to host the power management software - just a compatible Eaton UPS is required.

The solution consists of:

• VxRail version min. 4.5.300, 4.7.x, 7.0.x and above
• Eaton IPM SW v 1.67.243 or above
• Eaton UPS – 5P, 5PX, 9PX, 9SX, 93PM, 93E, 9PXM
• Eaton M2 Network Card FW v 1.7.5
• IPM Gold License Perpetual

The main benefits are:

• Preserving data integrity and business continuity by enabling automated and graceful shutdown of VxRail clusters that are experiencing unplanned extended power events
• Reducing the need for onsite IT staff with simple set-up and remote management of power infrastructure using familiar VMware tools
• Safeguarding the VxRail system from power anomalies and environmental threats

How does it work?

It’s quite simple (see the figure below). What’s interesting and unique is that the IPM software, which is running on the cluster, delegates the final shutdown of the system VMs and cluster to the card in the UPS device, and the card uses VxRail APIs to execute the cluster shutdown.

Figure 1. Eaton UPS and VxRail integration explained

Summary

Protection against unplanned power events should be a part of a business continuity strategy for all customers who run their critical workloads on VxRail. This ensures data integrity by enabling automated and graceful shutdown of VxRail cluster(s). Eaton’s solution is a great example of providing such protection and how Dell Technologies partners can leverage VxRail APIs to provide additional value for our joint customers.

VxRail REST APIs

The Challenge

VxRail Manager, available as a part of HCI System Software, drastically simplifies the lifecycle management and operations of a single VxRail cluster. With a “single click” user experience available directly in vCenter interface, you can perform a full upgrade off all software components of the cluster, including not only vSphere and vSAN, but also complete server hardware firmware and drivers, such as NICs, disk controller(s), drives, etc. That’s a simplified experience that you won’t find in any other VMware-based HCI solution.

But what if you need to manage not a single cluster, but a farm consisting of dozens or hundreds of VxRail clusters? Or maybe you’re using some orchestration tool to holistically automate the IT infrastructure and processes? Would you still need to login manually as an operator to each of these clusters separately and click a button to maybe shutdown a cluster, collect log information or health data or perform LCM operations?

This is where VxRail REST APIs come in handy.

The VxRail API Solution

REST APIs are very important for customers who would like to programmatically automate operations of their VxRail-based IT environment and integrate with external configuration management or cloud management tools.

In VxRail HCI System Software 4.7.300 we’ve introduced very significant improvements in this space:

• Swagger integration - which allows for simplified consumption of the APIs and their documentation;
• Comprehensiveness – we’ve almost doubled the number of public APIs available;
• PowerShell integration – that allows consumption of the APIs from the Microsoft PowerShell or VMware PowerCLI.

The easiest way to start using and access these APIs is through the web browser, thanks to the Swagger integration. Swagger is an Open Source toolkit that simplifies Open API development and can be launched from within the VxRail Manager virtual appliance. To access the documentation, simply open the following URL in the web browser: https://<VxM_IP>/rest/vxm/api-doc.html (where <VxM IP> stands for the IP address of the VxRail Manager) and you should see a page similar to the one shown below:

Figure 1. Sample view into VxRail REST APIs via Swagger

This interface is dedicated for customers, who are leveraging orchestration or configuration management tools – they can use it to accelerate integration of VxRail clusters into their automation workflows. VxRail API is complementary to the APIs offered by VMware.

Would you like to see this in action? Watch the first part of the recorded demo available in the additional resources section.

PowerShell integration for Windows environments

Customers, who prefer scripting in Windows environment, using Microsoft PowerShell or VMware PowerCLI, will benefit from VxRail.API PowerShell Modules Package. It simplifies the consumption of the VxRail REST APIs from PowerShell and focuses more on the physical infrastructure layer, while management of VMware vSphere and solutions layered on the top (such as Software-Defined Data Center, Horizon, etc.), can be scripted using similar interface available in VMware PowerCLI.

Figure 2. VxRail.API PowerShell Modules Package

To see that in action, check the second part of the recorded demo available in the additional resources section.

Bringing it all together

VxRail REST APIs further simplify IT Operations, fostering operational freedom and a reduction in OPEX for large enterprises, service providers and midsize enterprises. Integrations with Swagger and PowerShell make them much more convenient to use. This is an area of VxRail HCI System Software that rapidly gains new capabilities, so please make sure to check the latest advancements with every new VxRail release.

The latest VCF on VxRail release delivers GenAI-ready infrastructure, runs more demanding workloads, and is an excellent choice for supporting hardware tech refreshes and achieving higher consolidation ratios.

VMware Cloud Foundation 5.1.1 on VxRail 8.0.210 is a minor release from the perspective of versioning and new functionality but is significant in terms of support for the latest VxRail hardware platforms. This new release is based on the latest software bill of materials (BOM) featuring vSphere 8.0 U2b, vSAN 8.0 U2b, and NSX 4.1.2.3. Read on for more details…

VxRail hardware platform updates

16th generation VxRail VE-660 and VP-760 hardware platform support

Cloud Foundation on VxRail customers can now benefit from the latest, more scalable, and robust 16^th generation hardware platforms. This includes a full spectrum of hybrid, all-flash, and all NVMe options that have been qualified to run VxRail 8.0.210 software. This is fantastic news as these new hardware options bring many technical innovations, which my colleagues discussed in detail in previous blogs.

These new hardware platforms are based on Intel® 4th Generation Xeon® Scalable processors, which increase VxRail core density per socket to 56 (112 max per node). They also come with built-in Intel® AMX accelerators (Advanced Matrix Extensions) that support AI and HPC workloads without the need for additional drivers or hardware.

VxRail on the 16^th generation hardware supports deployments with either vSAN Original Storage Architecture (OSA) or vSAN Express Storage Architecture (ESA). The VP-760 and VE-660 can take advantage of vSAN ESA’s single-tier storage architecture, which enables RAID-5 resiliency and capacity with RAID-1 performance.

This table summarizes the configurations of the newly added platforms:

To learn more about the VE-660 and VP-760 platforms, please check Mike Athanasiou’s VxRail’s Latest Hardware Evolution blog. To learn more about Intel® AMX capability set, make sure to check out the VxRail and Intel® AMX, Bringing AI Everywhere blog, authored by Una O’Herlihy.

VCF on VxRail LCM updates

Support upgrades to VCF 5.1.1 from existing VCF 4.4.x and higher environments (N-3 upgrade support)

Customers who already upgraded to VCF 5.x are already familiar with the concept of the skip-level upgrade, which allows them to upgrade directly to the latest 5.x release without the need to perform upgrades to the interim versions. It significantly reduces the time required to perform the upgrade and enhances the overall upgrade experience. VCF 5.1.1 introduces so-called “N-3” upgrade support (as illustrated on the following diagram), which supports the skip-level upgrade for VCF 4.4.x. This means they can now perform a direct LCM upgrade operation from VCF 4.4.x, 4.5.x, 5.0.x, and 5.1.0 to VCF 5.1.1.

VCF licensing changes

Simplified licensing using a single solution license key

Starting with VCF 5.1.1, vCenter Server, ESXi, and TKG component licenses are now entered using a single “VCF Solution License” key. This helps to simplify the licensing by minimizing the number of individual component keys that require separate management. VMware NSX Networking, HCX, and VMware Aria Suite components are automatically entitled from the vCenter Server post-deployment. The single licensing key and existing keyed licenses will continue to work in parallel.

Removal of VCF+ cloud-connected subscriptions as a supported VCF licensing type

The other significant licensing change is the deprecation of VCF+ licensing, which the new subscription model has replaced.

Support for deploying or expanding VCF instances using Evaluation Mode

VMware Cloud Foundation 5.1.1 allows deploying a new VCF instance in evaluation mode without needing to enter license keys. An administrator has 60 days to enter licensing for the deployment, and SDDC Manager is fully functional at this time. The workflows for expanding a cluster, adding a new cluster, or creating a VI workload domain also provide an option to license later within a 60 day timeframe.

For more comprehensive information about changes in VCF licensing, please consult the VMware website.

Core VxRail enhancements

Support for remote vCenter plug-in

One of the notable enhancements in VxRail 8.0.210 is adopting the vSphere Client remote plugin architecture. It showcases adopting the latest vSphere architecture guidelines, as the local plug-ins are deprecated in vSphere 8.0 and won’t be supported in vSphere 9.0. The vSphere Client remote plug-in architecture allows plug-in functionality integration without running inside a vCenter Server. It’s a more robust architecture that separates vCenter Server from plug-ins and provides more security, flexibility, and scalability when choosing the programming frameworks and introducing new features. Starting with 8.0.210, a new VxRail Manager remote plug-in is deployed in the VxRail Manager Appliance.

LCM enhancements, including improved VxRail pre-checks and self-remediation of iDRAC issues.

VxRail 8.0.210 also comes with several small features based on Customer feedback that combine to improve the LCM experience's reliability. These include:

• VxRail Manager root disk space precheck prevents the upgrade errors related to lack of disk space (for rpm-based upgrades).
• Self-remediation of iDRAC issues during LCM upgrades provides a more reliable firmware upgrade experience. By clearing the iDRAC job queue and resetting the iDRAC, the process may recover from a firmware update failure.

Serviceability enhancements, including improved expansion pre-checks, external storage reporting, and improved troubleshooting capabilities.

Another group of features contributes to overall improved serviceability and visibility into the system:

• The UI now implements new errors and warnings for incompatible disks when the user tries to add an incompatible disk during the disk addition process (see the following figure)
• The improved hardware views report on storage capacity and utilization for dynamic nodes, improving the overall visibility for the external storage attached to dynamic nodes directly from the vSphere Client.
• VxRail cluster troubleshooting efficiency has improved thanks to better standardization of log format and event grooming for disk exhaustion.
• The improved node-add health checks reduce the risk of successfully adding a faulty or mismatched node to a VxRail cluster.

VMware Private AI Foundation with NVIDIA

With VCF 5.1.1, VMware introduces VMware Private AI Foundation with NVIDIA as Initial Access. Dell Technologies Engineering intends to validate this feature when it is generally available.

This solution aims to enable enterprise customers to adopt Generative AI capabilities more easily and securely by providing enterprises with a cost-effective, high-performance, and secure environment for delivering business value from Large Language Models (LLMs) using their private data.

Summary

The new VCF 5.1.1 on VxRail 8.0.210 release is an excellent option for customers looking for a hardware refresh, Gen AI-ready infrastructure to run more demanding workloads, or to achieve higher consolidation ratios. Additional enhancements introduced in the core VxRail functionality improve the overall LCM experience, serviceability, and visibility into the system.

Well-managed companies are always looking for new ways to increase efficiency and reduce costs while maintaining excellence in the quality of their products and services. Hence, IT departments and service providers look at the cloud and Application Programming Interfaces (APIs) as the enablers for automation, driving efficiency, consistency, and cost-savings.

This blog helps you get started with VxRail API by grouping the most useful VxRail API resources available from various public sources in one place. This list of resources is updated every few months. Consider bookmarking this blog as it is a useful reference.

Before jumping into the list, it is essential to answer some of the most obvious questions:

What is VxRail API?

VxRail API is a feature of the VxRail HCI System Software that exposes management functions with a RESTful application programming interface. It is designed for ease of use by VxRail customers and ecosystem partners who want to better integrate third-party products with VxRail systems. VxRail API is:

• Simple to use— Thanks to embedded, interactive, web-based documentation, and PowerShell and Ansible modules, you can easily consume the API using a supported web browser, using a familiar command line interface for Windows and VMware vSphere admins, or using Ansible playbooks.
• Powerful—VxRail offers dozens of API calls for essential operations such as automated life cycle management (LCM), and its capabilities are growing with every new release.
• Extensible—This API is designed to complement REST APIs from VMware (such as vSphere Automation API, PowerCLI, and VMware Cloud Foundation on Dell EMC VxRail API), offering a familiar look and feel and vast capabilities.

Why is VxRail API relevant?

VxRail API enables you to use the full power of automation and orchestration services across your data center. This extensibility enables you to build and operate infrastructure with cloud-like scale and agility. It also streamlines the integration of the infrastructure into your IT environment and processes. Instead of manually managing your environment through the user interface, the software can programmatically trigger and run repeatable operations.

More customers are embracing DevOps and Infrastructure as Code (IaC) models because they need reliable and repeatable processes to configure the underlying infrastructure resources that are required for applications. IaC uses APIs to store configurations in code, making operations repeatable and greatly reducing errors.

How can I start? Where can I find more information?

To help you navigate through all available resources, I grouped them by level of technical difficulty, starting with 101 (the simplest, explaining the basics, use cases, and value proposition), through 201, up to 301 (the most in-depth technical level).

VxRail Edge Automation Unleashed

Simplifying Satellite Node Management with Ansible

In the previous blog, Infrastructure as Code with VxRail made easier with Ansible Modules for Dell VxRail, I introduced the modules which enable the automation of VxRail operations through code-driven processes using Ansible and VxRail API. This approach not only streamlines IT infrastructure management but also aligns with Infrastructure as Code (IaC) principles, benefiting both technical experts and business leaders.

The corresponding demo is available on YouTube:

The previous blog laid the foundation for the continued journey where we explore more advanced Ansible automation techniques, with a focus on satellite node management in the VxRail ecosystem. I highly recommend checking out that blog before diving deeper into the topics discussed here - as the concepts discussed in this demo will be much easier to absorb

What are the VxRail satellite nodes?

VxRail satellite nodes are individual nodes designed specifically for deployment in edge environments and are managed through a centralized primary VxRail cluster. Satellite nodes do not leverage vSAN to provide storage resources and are an ideal solution for those workloads where the SLA and compute demands do not justify even the smallest of VxRail 2-node vSAN clusters.

Satellite nodes enable customers to achieve uniform and centralized operations within the data center and at the edge, ensuring VxRail management throughout. This includes comprehensive, automated lifecycle management for VxRail satellite nodes, while encompassing hardware and software and significantly reducing the need for manual intervention.

To learn more about satellite nodes, please check the following blogs from my colleagues:

• David’s introduction: Satellite nodes: Because sometimes even a 2-node cluster is too much
• Stephen’s update on enhancements: Enhancing Satellite Node Management at Scale

Automating VxRail satellite node operations using Ansible

You can leverage the Ansible Modules for Dell VxRail to automate various VxRail operations, including more advanced use cases, like satellite node management. It’s possible today by using the provided samples available in the official repository on GitHub.

Have a look at the following demo, which leverages the latest available version of these modules at the time of recording – 2.2.0. In the demo, I discuss and demonstrate how you can perform the following operations from Ansible:

• Collecting information about the number of satellite nodes added to the primary VxRail cluster
• Adding a new satellite node to the primary VxRail cluster
• Performing lifecycle management operations – staging the upgrade bundle and executing the upgrade on managed satellite nodes
• Removing a satellite node from the primary cluster

The examples used in the demo are slightly modified versions of the following samples from the modules' documentation on GitHub. If you’d like to replicate these in your environment, here are the links to the corresponding samples for your reference, which need slight modification:

• Retrieving system information: systeminfo.yml
• Adding a new satellite node: add_satellite_node.yml
• Performing LCM operations: upgrade_host_folder.yml (both staging and upgrading as explained in the demo)
• Removing a satellite node: remove_satellite_node.yml.

In the demo, you can also observe one of the interesting features of the Ansible Modules for Dell VxRail that is shown in action but not explained explicitly. You might be aware that some of the VxRail API functions are available in multiple versions – typically, a new version is made available when some new features are available in the VxRail HCI System Software, while the previous versions are stored to provide backward compatibility. The example is “GET /vX/system”, which is used to retrieve the number of the satellite nodes – this property was introduced in version 4. If you avoid specifying the version, the modules will automatically select the latest supported version, simplifying the end-user experience.

How can you get more hands-on experience with automating VxRail operations programmatically?

The above demo, discussing the satellite nodes management using Ansible, was configured in the VxRail API hands-on lab which is available in the Dell Technologies Demo Center. With the help of the Demo Center team, we built this lab as the self-education tool for learning VxRail API and how it can be used for automating VxRail operations using various methods – through exploring the built-in, interactive, web-based documentation, VxRail API PowerShell Modules, Ansible Modules for Dell VxRail and Postman.

The hands-on lab provides a safe VxRail API sandbox, where you can easily start experimenting by following the exercises from the lab guide or trying some other use cases on your own without any concerns about making configuration changes to the VxRail system.

The lab was refreshed for the Dell Technologies World 2023 conference to leverage VxRail HCI System Software 8.0.x and the latest version of the Ansible Modules. If you’re a Dell partner, you should have access directly, and if you’re a customer who’d like to get access – please contact your Account SE from Dell or Dell Partner. The lab is available in the catalog as: “HOL-0310-01 - Scalable Virtualization, Compute, and Storage with the VxRail REST API”.

Conclusion

In the fast-evolving landscape of IT infrastructure, the ability to automate operations efficiently is not just a convenience but a necessity. With the power of Ansible Modules for Dell VxRail, we've explored how this necessity can be met, looking at the examples of satellite nodes use case. We encourage you to embrace the full potential of VxRail automation using VxRail API and Ansible or other tools. If it is something new, you can get the experience by experimenting with the hands-on lab available in the Demo Center catalog.

A more flexible and scalable hybrid cloud platform with simpler upgrades from previous releases

The latest release of the co-engineered turnkey hybrid cloud platform is now available, and I wanted to take this great opportunity to discuss its enhancements.

Many new features are included in this major release, including support for the latest VCF and VxRail software component versions based on the latest vSphere 8.0 U1 virtualization platform generation, and more. Read on for the details!

In-place upgrade lifecycle management enhancements

Support for automated in-place upgrades from VCF 4.3.x and higher to VCF 5.0

This is the most significant feature our customers have been waiting for. In the past, due to significant architectural changes between major VCF releases and their SDDC components (such as NSX), a migration was required to move from one major version to the next. (Moving from VCF 4.x to VCF 5.x is considered a major version upgrade.) In this release, this type of upgrade is now drastically improved.

After the SDDC Manager has been upgraded to version 5.0 (by downloading the latest SDDC Manager update bundle and performing an in-place automated SDDC Manager orchestrated LCM update operation), an administrator can follow the new built-in SDDC Manager in-place upgrade workflow. The workflow is designed to assist in upgrading the environment without needing any migrations. Domains and clusters can be upgraded sequentially or in parallel. This reduces the number and duration of maintenance windows, allowing administrators to complete an upgrade in less time. Also, VI domain skip-level upgrade support allows customers to run VCF 4.3.x or VCF 4.4.x BOMs in their domains to streamline their upgrade path to VCF 5.0, by skipping intermediary VCF 4.4.x and 4.5.x versions respectively. All this is performed automatically as part of the native SDDC Manager LCM workflows.

What does this look like from the VCF on VxRail administrator’s perspective? The administrator is first notified that a new SDDC Manager 5.0 upgrade is available. Administrators will be guided first to update their SDDC Manager instance to version 5.0. With SDDC Manager 5.0 in place, administrators can take advantage of the new enhancements which streamline the in-place upgrade process that can be used for the remaining components in the environment. These enhancements follow VMware best practices, reduce risk, and allow administrators to upgrade the full stack of the platform in a staged manner. These enhancements include:

• Context aware prechecks
• vRealize Suite prechecks
• Config drift awareness
• vCenter Server migration workflow
• Licensing update workflow

The following image highlights part of the new upgrade experience from the SDDC Manager UI. First, on the updates tab for a given domain, we can see the availability of the upgrade from VCF 4.5.1 to VCF 5.0.0 on VxRail 8.0.100 (Note: In this example, the first upgrade bundle for the SDDC Manager 5.0 was already applied.)

When the administrator clicks View Bundles, SDDC Manager displays a high-level workflow that highlights the upgrade bundles that would be applied, and in which order.

To see the in-place upgrade in action, check out the following demo:

Now let’s dive a little deeper into the upgrade workflow steps. The following diagram depicts the end-to-end workflow for performing an in-place LCM upgrade from VCF 4.3.x/4.4.x/4.5.x to VCF 5.0 for the management domain.

The in-place upgrade workflow for the management domain consists of the following six steps:

1. Plan and prepare by ensuring all important prerequisites are met (for example, the minimum supported VCF on VxRail version for an in-place upgrade is validated, in-place upgrade supported topologies are being used, and so on).
2. Run an update precheck and resolve any issues before starting the upgrade process.
3. Download the VMware Cloud Foundation and VxRail Upgrade Bundles from the Online Depot within SDDC Manager using a MyVMware account and a Dell support online depot account respectively.
4. Upgrade components using the automated guided workflow, including SDDC Manager, NSX-T Data Center, vCenter Server for VCF, and VxRail hosts.
5. Apply configuration drifts, which capture required configuration changes between release versions.
6. When the upgrade is completed, update component licensing using the built-in SDDC Manager workflow (only applicable for VCF instances deployed using perpetual licensing).

Upgrading workload domains follows a similar workflow.

If performed manually, the in-place upgrade process to VCF 5.0 on VxRail 8.0.100 from previous releases would be potentially error-prone and time-consuming. The guided, simplified, and automated experience now provided in SDDC Manager 5.0 greatly reduces the effort and risk for customers, by helping them perform this operation in a fully controlled, guided, and automated manner on their own, providing a much better user experience and better value.

SDDC Manager context aware prechecks

Keeping a large-scale cloud environment in a healthy, well-managed state is very important to achieve the desired service levels and increase the success rate of LCM operations. In SDDC Manager 5.0, prechecks have been further enhanced and are now context aware. But what does this mean?

Before performing the upgrade, administrators can choose to run a precheck against a specific VCF release (“Target Version”) or run a “General Update Readiness” precheck. Each type of precheck allows the administrator to select the specific VCF on VxRail objects to run the precheck on. For example, an administrator can run it against an entire domain, a VxRail cluster, or even an individual SDDC software component such as NSX and vRealize/Aria Suite components. For example, a precheck can be run at a per-VxRail cluster level, which might be useful for large workload domains configured with multiple clusters. It could reduce planned maintenance windows by updating components of the domain separately.

But what is the difference between the “Target Version” and “General Upgrade Readiness” precheck types? Let me explain:

• Target Version precheck - Prechecks for a specific “Target Version” will run prechecks related to the components between the source and target VCF on VxRail release. (Note that the drop-down in the SDDC Manager UI will only show target versions from VCF 5.x on VxRail 8.x after the SDDC Manager has been updated to 5.0). This feature reduces the risk of issues during the upgrade to the target VCF release.
• General Upgrade Readiness precheck - The “General Upgrade Readiness” precheck can be run any time to plan and assess upgrade readiness without triggering the upgrade. The “General Upgrade Readiness” precheck can periodically run as a health check on a given SDDC component.

The following screenshot shows what this feature looks like from the system administrator perspective in the SDDC Manager UI:

Platform security and scalability enhancements

Isolated domains with individual SSO

Another significant new feature I’d like to highlight is the introduction of Isolated workload domains. This has a significant impact on both the security and scalability of the platform.

In the past, VMware Cloud Foundation 4.x deployments by design have been configured to use a single SSO instance shared between the management domain and all VI workload domains (WLDs). All WLDs’ vCenter Servers are connected to each other using Enhanced Linked Mode (ELM). After a user is logged into SDDC Manager, ELM provides seamless access to all the products in the stack without being challenged to authenticate again.

VCF 5.0 on VxRail 8.0.100 deployments allow administrators to configure new workload domains using separate SSO instances. These are known as Isolated domains. This capability can be very useful, especially for Managed Service Providers (MSPs) who can allocate Isolated workload domains to different tenants with their own SSO domains for better security and separation between the tenant environments. Each Isolated SSO domain within VCF 5.0 on VxRail 8.0.100 is also configured with its own NSX instance.

As a positive side effect of this new design, the maximum number of supported domains per VCF on VxRail instance has now been increased to 25 (this includes the management domain and assumes all workload domains are deployed as isolated domains). This scalability enhancement results from not hitting the max number of vCenters configured in an ELM instance (which is 15) because Isolated domains are not configured with ELM with the management SSO domain. So, increasing the security and separation between the workload domains can also increase the overall scalability of the VCF on VxRail cloud platform.

The following diagram illustrates how customers can increase the scalability of the VCF on VxRail platform by adding isolated domains with their dedicated SSO:

What does this new feature look like from the VCF on VxRail administrator’s perspective?

When creating a new workload domain, there’s a new option in the UI wizard allowing either to join the new WLD into the management SSO domain or create a new SSO domain:

After the SSO domain is created, its information is shown in the workload domain summary screen:

General LCM updates

VxRail accurate versioning support and SDDC Manager ‘Release Versions’ UI and API enhancements

These two features should be discussed together. Beginning in VCF 5.0 on VxRail 8.0.100 and higher, enhancements were made to the SDDC Manager LCM service that enables more granular compatibility and tracking of current and previous VxRail versions that are compatible with current and previous VCF versions. This opens VCF on VxRail to be more flexible by supporting different VxRail versions within a given VCF release. It allows admins to support applying and tracking asynchronous VxRail release patches outside of the 1:1 mapped, fully compatible VCF on VxRail release that could require waiting for it to be available. This information about available and supported release versions for VCF and VxRail is integrated into the SDDC Manager UI and API.

Flexible WLD target versions

VCF 5.0 on VxRail 8.0.100 introduces the ability for each workload domain to have different versions as far back as N-2 releases, where N is the current version on the management domain. With this new flexibility, VCF on VxRail administrators are not forced to upgrade workload domain versions to match the management domain immediately. In the context of VCF 5.0 on VxRail 8.0.100, this can help admins plan upgrades over a long period of time when maintenance windows are tight.

SDDC Manager config drift awareness

Each VMware Cloud Foundation release introduces several new features and configuration changes to its underlying components. Update bundles contain these configuration changes to ensure an upgraded VCF on VxRail instance will function like a greenfield deployment of the same version. Configuration drift awareness allows administrators to view parameters and configuration changes as part of the upgrade. An example of configuration drift is adding a new service account or ESXi lockdown enhancement. This added visibility helps customers better understand new features and capabilities and their impact on their deployments.

The following screenshot shows how this new feature appears to the administrator of the platform:

SDDC Manager prechecks for vRealize/Aria Suite component versions

SDDC Manager 5.0 allows administrators to run a precheck for vRealize/VMware Aria Suite component compatibility. The vRealize/Aria Suite component precheck is run before upgrading core SDDC components (NSX, vCenter Server, and ESXi) to a newer VCF target release, and can be run from VCF 4.3.x on VxRail 7.x and above. The precheck will verify if all existing vRealize/Aria Suite components will be compatible with core SDDC components of a newer VCF target release by checking them against the VMware Product Interoperability Matrix.  

General security updates

Enhanced certificate management

VCF 5.0 on VxRail 8.0.100 contains improved workflows that orchestrate the process of configuring Certificate Authorities and Certificate Signing Requests. Administrators can better manage certificates in VMware Cloud Foundation, with improved certificate upload and installation, and new workflows to ensure certificate validity, trust, and proper installation. These new workflows help to reduce configuration time and minimize configuration errors.

Storage updates

Support for NVMe over TCP connected supplemental storage

Supplemental storage can be used to add storage capacity to any domain or cluster within VCF, including the management domain. It is configured as a Day 2 operation. What’s new in VCF 5.0 on VxRail 8.0.100 is the support for the supplemental storage to be connected with the NVMe over TCP protocol.

Administrators can benefit from using NVMe over TCP storage in a standard Ethernet-based networking environment. NVMe over TCP can be more cost-efficient than NVMe over FC and eliminates the need to deploy and manage a fiber channel fabric if that is what an organization requires.

Operations and serviceability updates

VCF+ enhancements

VMware Cloud Foundation+ has been enhanced for the VCF 5.0 release, allowing greater scale and integrated lifecycle management. First, the scalability increased – it allows administrators to connect up to eight domains per VCF instance (including the management domain) to the VMware Cloud portal. Second, updates to the Lifecycle Notification Service within the VMware Cloud portal provide visibility of pending updates to any component within the VCF+ Inventory. Administrators can initiate updates through the VCF+ Lifecycle Management Notification Service, which connects back to the specific SDDC Manager instance to be updated. From here, administrators can use familiar SDDC Manager prechecks and workflows to update their environment.   

VxRail hardware platform updates

Support for single socket 15G VxRail P670F

A new VxRail hardware platform is now supported, providing customers more flexibility and choice. The single-socket VxRail P670F, a performance-focused platform, is now supported in VCF on VxRail deployments and can offer customers savings on software licensing in specific scenarios.

Other asynchronous release related updates

VCF Async Patch Tool 1.1.0.1 release

While not directly tied to VCF 5.0 on VxRail 8.0.100 release, VMware has also released the latest version of the VCF Async Patch Tool. This latest version now supports applying patches to VCF 5.0 on VxRail 8.0.100 environments.

Summary

VMware Cloud Foundation 5.0 on Dell VxRail 8.0.100 is a new major platform release based on the latest generation of VMware’s vSphere 8 hypervisor. It provides several exciting new capabilities, especially around automated upgrades and lifecycle management. This is the first major release that provides guided, simplified upgrades between the major releases directly in the SDDC Manager UI, offering a much better experience and more value for customers.

All of this makes the new VCF on VxRail release a more flexible and scalable hybrid cloud platform, with simpler upgrades from previous releases, and lays the foundation for even more beneficial features to come.

VxRail Videos

Many customers are looking at Infrastructure as Code (IaC) as a better way to automate their IT environment, which is especially relevant for those adopting DevOps. However, not many customers are aware of the capability of accelerating IaC implementation with VxRail, which we have offered for some time already—Ansible Modules for Dell VxRail.

What is it? It's the Ansible collection of modules, developed and maintained by Dell, that uses the VxRail API to automate VxRail operations from Ansible.

By the way, if you're new to the VxRail API, first watch the introductory whiteboard video available on YouTube.

Ansible Modules for Dell VxRail are well-suited for IaC use cases. They are written in such a way that all requests are idempotent and hence fault-tolerant. This means that the result of a successfully performed request is independent of the number of times it is run.

Besides that, instead of just providing a wrapper for individual API functions, we automated holistic workflows (for instance, cluster deployment, cluster expansion, LCM upgrade, and so on), so customers don't have to figure out how to monitor the operation of the asynchronous VxRail API functions.  These modules provide rich functionality and are maintained by Dell; this means we're introducing new functionality over time. They are already mature—we recently released version 1.4.

Finally, we are also reducing the risk for customers willing to adopt the Ansible modules in their environment, thanks to the community support model, which allows you to interact with the global community of experts. From the implementation point of view, the architecture and end-user experience are similar to the modules we provide for Dell storage systems.

Getting Started

Ansible Modules for Dell VxRail are available publicly from the standard code repositories: Ansible Galaxy and GitHub. You don't need a Dell Support account to download and start using them.

Requirements

The requirements for the specific version are documented in the "Prerequisites" section of the description/README file.

In general, you need a Linux-based server with the supported Ansible and Python versions. Before installing the modules, you have to install a corresponding, lightweight Python SDK library named "VxRail Ansible Utility," which is responsible for the low-level communication with the VxRail API. You must also meet the minimum version requirements for the VxRail HCI System Software on the VxRail cluster.

This is a summary of requirements for the latest available version (1.4.0) at the time of writing this blog:

Installation

You can install the SDK library by using git and pip commands. For example:

git clone https://github.com/dell/ansible-vxrail-utility.git

cd ansible-vxrail-utility/
pip install .

Then you can install the collection of modules with this command:

ansible-galaxy collection install dellemc.vxrail:1.4.0

Testing

After the successful installation, we're ready to test the modules and communication between the Ansible automation server and VxRail API.

I recommend performing that check with a simple module (and corresponding API function) such as dellemc_vxrail_getsysteminfo, using GET /system to retrieve VxRail System Information.

Let's have a look at this example (you can find the source code on GitHub):

 
Note that this playbook is run on a local Ansible server (localhost), which communicates with the VxRail API running on the VxRail Manager appliance using the SDK library. In the vars section, , we need to provide, at a minimum, the authentication to VxRail Manager for calling the corresponding API function. We could move these variable definitions to a separate file and include the file in the playbook with vars_files. We could also store sensitive information, such as passwords, in an encrypted file using the Ansible vault feature. However, for the simplicity of this example, we are not using this option.

After running this playbook, we should see output similar to the following example (in this case, this is the output from the older version of the module):

Cluster expansion example

Now let's have a look at a bit more sophisticated, yet still easy-to-understand, example. A typical operation that many VxRail customers face at some point is cluster expansion. Let's see how to perform this operation with Ansible (the source code is available on GitHub):

In this case, I've exported the definitions of the sensitive variables, such as vcpasswd, mgt_passwd, and root_passwd, into a separate, encrypted Ansible vault file, sensitive-vars.yml, to follow the best practice of not storing them in the clear text directly in playbooks.

As you can expect, besides the authentication, we need now to provide more parameters—configuration of the newly added host—defined in the vars section. We select the new host from the pool of available hosts, using the PSNT identifier (host_psnt variable).

This is an example of an operation performed by an asynchronous API function. Cluster expansion is not something that is completed immediately but takes minutes. Therefore, the progress of the expansion is monitored in a loop until it finishes or the number of retries is passed. If you communicated with the VxRail API directly by using the URI module from your playbook, you would have to take care of such monitoring logic on your own; here, you can use the example we provide.

You can watch the operation of the cluster expansion Ansible playbook with my commentary in this demo: 

Getting help

The primary source of information about the Ansible Modules for Dell VxRail is the documentation available on GitHub. There you'll find all the necessary details on all currently available modules, a quick description, supported endpoints (VxRail API functions used), required and optional parameters, return values, and location of the log file (modules have built-in logging feature to simplify troubleshooting— logs are written in the /tmp directory on the Ansible automation server). The GitHub documentation also contains multiple samples showing how to use the modules, which you can easily clone and adjust as needed to the specifics of your VxRail environment.

There's also built-in documentation for the modules, accessible with the ansible-doc command.

Finally, the Dell Automation Community is a public discussion forum where you can post your questions and ask for help as needed.

Conclusion 

I hope you now understand the Ansible Modules for Dell VxRail and how to get started. Let me quickly recap the value proposition for our customers. The modules are well-suited for IaC use cases, thanks to automating holistic workflows and idempotency. They are maintained by Dell and supported by the Dell Automation Community, which reduces risk. These modules are much easier to use than the alternative of accessing the VxRail API on your own. We provide many examples that can be adjusted to the specifics of the customer’s environment.

In my previous blog, Protecting VxRail from Power Disturbances, I described the first API-integrated solution that helps customers preserve data integrity on VxRail if there are unplanned power events. Today, I'm excited to introduce another solution that resulted from our close partnership with Schneider Electric (APC).

Why is it important?

Over the last few years, VxRail has become a critical HCI system and data-center building block for over 15,000 customers who have deployed more than 220,000 nodes globally. When HCI was first introduced, it was often considered for specific workloads such as VDI or ROBO locations. However, with the evolution of hardware and software capabilities, VxRail became a catalyst in data-center modernization, deployed across various use cases from core to cloud to edge. Today, customers are deploying VxRail for mission-critical workloads because it is powerful enough to meet the most demanding requirements for performance, capacity, availability, and rich data services.

Dell Technologies is a leader in data-protection solutions and offers a portfolio of products that can fulfill even the most demanding RPO and RTO requirements from customers. In addition to using traditional data-protection solutions, it is best practice to use a UPS to protect the infrastructure and ensure data integrity if there are unplanned power events. In this blog, I want to highlight a new solution from Schneider Electric, the provider of APC Smart-UPS systems.

The APC UPS protection solution for VxRail

Schneider Electric is one of Dell Technologies’ strategic partners in the Extended Technologies Complete Program. It provides Dell Technologies with APC UPS and IT rack enclosures offering a comprehensive solution set of infrastructure hardware, monitoring, management software, and service options.

PowerChute Network Shutdown in version 4.5 seamlessly integrates with VxRail by communicating over the network with the APC UPS. If there is a power outage, PowerChute can gracefully shut down VxRail clusters using the VxRail API. As a result of this integration, PowerChute can run on the same protected VxRail cluster, saving space and reducing hardware costs.

Solution components:

• VxRail cluster with VxRail HCI System Software version 7.0.320, 4.7.540 or higher
• Dell Smart-UPS Online 5kVA DLRT5KRMXLT or Dell Smart-UPS Online 3kVA DLRT3000RMXLA
• UPS Network Management Card 3 (AP9640, AP9640, or AP9643) with NMC firmware version v2.2 or higher
• Either a 1-Year or 3-Year PowerChute license for each VxRail node in the cluster (PowerChute Network Shutdown software version 4.5 or higher)

Key benefits of this solution include:

• Unattended, graceful shutdown of virtual machines (VMs), followed by the VxRail cluster that avoids data corruption thanks to integration with the VxRail API.
• Minimal downtime after critical events have passed with a pre-configured automated start-up sequence, which is useful at remote or unattended sites.
• Full deployment within the VxRail cluster saves space and reduces hardware requirements since you don't have to deploy PowerChute on a separate machine outside the cluster.
• Edge-ready with support for Edge-ready vSAN architecture with vSAN 2-node clusters.
• Redundant VxRail API-based cluster shutdown. In a redundant UPS set-up, if one NMC3 is offline, PowerChute will connect to one or more available NMC3s to carry out the VxRail cluster shutdown.

How does it work?

This is easiest to describe using the following diagram, which covers the steps taken in a power event and when the event is cleared:

How PowerChute Network Shutdown works with VxRail

I highly recommend watching the demo of this solution in action, which is listed in the Additional resources section at the end of this blog.

Summary

Protection against unplanned power events should be a part of a business continuity strategy for all customers who run their critical workloads on VxRail. This practice ensures data integrity by enabling automated and graceful shutdown of VxRail clusters. Customers now have more choice in providing such protection, with the new version of PowerChute Network Shutdown software for APC UPS systems integrated with VxRail API and validated with VxRail.

The challenge

Cybersecurity and protection against ransomware attacks are among the top priorities for most customers who have successfully implemented or are going through a digital transformation. According to the ESG’s 2022 Technology Spending Intentions Survey:

• 69 percent of respondents shared that their spending on cybersecurity will increase in 2022 (#1).
• 48 percent of respondents believe their IT organizations have a problematic shortage of existing skills in this area (#1).
• 38 percent of respondents believe that strengthening cybersecurity will drive the majority of technology spending in their organization in the next 12 months (#1).

The data clearly shows that this area is one of the top concerns for our customers today. They need solutions that significantly simplify increasing cybersecurity activities due to a perceived skills shortage.

It is worth reiterating the critical role that networking plays within Hyperconverged Infrastructure (HCI). In contrast to legacy three-tier architectures, which typically have a dedicated storage network and storage, HCI architecture is more integrated and simplified. Its design lets you share the same network infrastructure for workload-related traffic and intercluster communication with the software-defined storage. The accessibility of the running workloads (from the external network) depends on the reliability of this network infrastructure, and on setting it up properly. The proper setup also impacts the performance and availability of the storage and, as a result, the whole HCI system. To prevent human error, it is best to employ automated solutions to enforce configuration best practices.

VxRail as an HCI system supports VMware NSX, which provides tremendous value for increasing cybersecurity in the data center, with features like microsegmentation and AI-based behavioral analysis and prevention of threats. Although NSX is fully validated with VxRail as a part of VMware Cloud Foundation (VCF) on VxRail platform, setting it outside of VCF requires strong networking skills. The comprehensive capabilities of this network virtualization platform might be overwhelming for VMware vSphere administrators who are not networking experts. What if you only want to consume the security features? This scenario might present a common challenge, especially for customers who are deploying small VxRail environments with few nodes and do not require full VCF on the VxRail stack.

The great news is that VMware recognized these customer challenges and now offers a simplified method to deploy NSX for security use cases. This method fits the improved operational experience our customers are used to with VxRail. This experience is possible with a new VMware vCenter Plug-in for NSX, which we introduce in this blog.

NSX and security

NSX is a comprehensive virtualization platform that provides advanced networking and security capabilities that are entirely decoupled from the physical infrastructure. Implementing networking and security in software, distributed across the hosts responsible for running virtual workloads, provides significant benefits:

• Flexibility—Total flexibility for positioning workloads in the data center enables optimal use of compute resources (a key aspect of virtualization).
• Optimal consumption of CPU resources —Advanced NSX features only consume CPU from the hosts when they are used. This consumption leads to lower cost and simplified provisioning when compared to running the features on dedicated appliances.
• High performance—NSX features are performed in VMware ESXi kernel space, a unique capability on vSphere.

The networking benefits are evident for large deployments, with NSX running in almost all Fortune 100 companies and many medium scale businesses. In today’s world of widespread viruses, ransomware, and even cyber warfare, the security aspect of NSX built on top of the NSX distributed firewall (DFW) is relevant to vSphere customers, regardless of their size.

The NSX DFW is a software firewall instantiated on the vNICs of the virtual machines in the data center. Thanks to its inline position, it provides maximum filtering granularity because it can inspect the traffic coming in and going out of every virtual machine without requiring redirection of the traffic to a security appliance, as shown in the following figure. It also moves along with the virtual machine during vMotion and maintains its state.

Figure 1: Traditional firewall appliance compared to the NSX DFW

The NSX DFW state-of-the-art capabilities are configured centrally from the NSX Manager and allow implementing security policies independently of the network infrastructure. This method makes it easy to implement microsegmentation and compliance requirements without dedicating racks, servers, or subnets to a specific type of workload. With the NSX DFW, security teams can deploy advanced threat prevention capabilities such as distributed IDS/IPS, network sandboxing, and network traffic analysis/network detection and response (NTA/NDR) to protect against known and zero-day threats.

A dedicated solution for security

Many NSX customers who are satisfied with the networking capability of vSphere run their production environment on a VDS with VLAN-backed dvportgroups. They deploy NSX for its security features only, and do not need its advanced networking components. Until now, those customers had to migrate their virtual machines to NSX-backed dvportgroups to benefit from the NSX DFW. This migration is easy but managing networking from NSX modifies the workflow of all the teams, including those teams that are not concerned by security:

Figure 2: Traditional NSX deployment

Starting with NSX 3.2, you can run NSX security on a regular VDS, without introducing the networking components of NSX. The security team receives all the benefits of NSX DFW, and there is no impact to any other team:

Figure 3: NSX Security with vCenter Plugin

Even better, NSX can now integrate further with vCenter, thanks to a plug-in that allows you to configure NSX from the vCenter UI. This method means that NSX can be consumed as a simple security add-on for a traditional vSphere deployment.

How to deploy and configure NSX Security

Requirements

First, we need to ensure that our VxRail environment meets the following requirements:

• vCenter Server 7.0 U3c (included with VxRail 7.0.320)
• VDS 6.7 or later
• The OVA for NSX-T with the vCenter Plugin version 3.2 or later and an appropriate NSX license

Deploy the NSX Manager and the NSX DFW on ESXi hosts

Running NSX in a vSphere environment consists of deploying a single NSX Manager virtual machine protected by vSphere HA. A shortcut in vCenter enables this step:

Figure 4: Deploy the NSX Manager appliance virtual machine from the NSX tab in vCenter

When the NSX Manager is up and running, it sets up a one-to-one association with vCenter and uploads the plug-in that presents the NSX UI in vCenter, as if NSX security is part of vCenter. The vCenter administrator becomes an effective NSX security administrator.

The next step, performed directly from the vCenter UI, is to enter the NSX license and select the cluster on which to install the NSX DFW binaries:

Figure 5: Select the clusters that will receive the NSX DFW binaries

After the DFW binaries are installed on the ESXi hosts, the NSX security is deployed and operational. You can exit the security configuration wizard (and configure directly from the NSX view in the vCenter UI) or let the wizard run.

Run the security configuration wizard

After installing the NSX binaries on the ESXi hosts, the plug-in runs a wizard that guides you through the configuration of basic security rules according to VMware best practices. The wizard gives the vSphere administrator simple guidance for implementing a baseline configuration that the security team can build on later. There are three different steps in this guided workflow.

First step—Segment the data center in groups

Perform the following steps, as shown in the following figure:

• Create an infrastructure group, identifying the services that the workloads in the data center will access. These services typically include DNS, NTP, DHCP servers, and so on.
• Segment the data center coarsely in environments, such as groups like Development, Production, and DMZ.
• Segment the data center finely by identifying applications running across the different environments.

Figure 6: Example of group creation

Second step—Define communication between different groups

Perform the following steps, as shown in the following figure:

• Define which groups can access the infrastructure services
• Define how the different environments communicate with each other
• Define how applications communicate with each other

Figure 7: Define the communication between environments using a graphcial represenation

Third step—Review the configuration and publish it to the NSX DFW

After reviewing the configuration, publish the configuration to NSX:

Figure 8: Review DFW rules before exiting the wizard

The full NSX UI is now available in vCenter. Select the NSX tab to access the NSX UI directly.

Final thoughts

The new VMware vCenter Plug-in for NSX drastically simplifies the deployment and adoption of NSX with VxRail for security use cases. In the past, advanced knowledge of the network virtualization platform was required. A vSphere adminstrator can now deploy it easily, using an intuitive configuration wizard available directly from vCenter. 

The VMware vCenter Plug-in for NSX provides the kind of simplified and optimized experience that VxRail customers are used to when managing their HCI environment. It also addresses the challenge that customers face today, improving security even with a perceived shortage of skills in this area. Also, it can be configured easily and quickly, making the robust NSX security features more available for smaller HCI deployments.

Improved automated lifecycle management and new hardware options

Today (7/2), Dell Technologies is announcing General Availability of VMware Cloud Foundation 3.10.0.1 on VxRail 4.7.511. 

Why we are releasing 3.10.0.1?

Because we’ve been notified about an upcoming important patch for the Cloud Foundation version 3.10 from VMware, and we wanted to incorporate it in a GA version on VxRail for the best experience for our customers.

What’s New?

This new release introduces VCF enhancements and VxRail enhancements.

VMware Cloud Foundation 3.10.0.1 enhancements:

• ESXi Cluster-Level and Parallel Upgrades - Enables customers to update the ESXi software on multiple clusters in the management domain or in a workload domain in parallel. Parallel upgrades reduce the overall time required to upgrade the VCF environment. 

Figure 1. ESXi Cluster-Level and Parallel Upgrades

• NSX-T Data Center Cluster-Level and Parallel Upgrades - Enables customers to upgrade all edge clusters in parallel, and then all host clusters in parallel. Again, parallel upgrades reduce the overall time required to upgrade the VCF environment. There’s also a possibility to select specific clusters to upgrade, using multiple upgrade windows, so that there’s no requirement for all clusters to be available at a given time.
  
  

Figure 2. NSX-T Cluster-Level and Parallel Upgrades

• Skip Level Upgrades - Enables customers to upgrade to VMware Cloud Foundation on Dell EMC VxRail 3.10 from versions 3.7 and later.  Note: in case of VCF on VxRail, this must be performed by Dell EMC Customer Support at this time – customer enabled skip level upgrades will be supported when the feature is available in the GUI. Customers with active support contracts should open a Service Request with Dell EMC Customer Support to schedule the skip level upgrade activity.

Option to disable Application Virtual Networks (AVNs) during Bring-up - AVNs deploy vRealize Suite components on NSX overlay networks. We recommend using this option during bring-up. Customers can now disable this feature, for instance, if they are not planning to use vRealize Suite components.

• Support for multiple NSX-T Transport Zones - Some customers require this option due to their architecture/security standards, for even better separation of the network traffic. It’s now available as a Day 2 configuration option that can be enabled by customers or VMware Professional Services.
• BOM Updates - Updated Bill of Materials with new product versions. For an updated BOM, please consult the release notes.

VxRail 4.7.511 enhancements:

• VCF on VxRail login using RSA SecurID two-factor authentication - Allows customers to implement more secure, two-factor authentication for VCF on VxRail using the RSA SecurID solution.

• Support for new hardware options - Please check this blog post and the press release for more details on VxRail 4.7.510 platform features:

• Intel Optane Persistent Memory 
• VxRail D560 / D560F – ruggedized VxRail nodes
• VxRail E665/F/N – AMD-based VxRail nodes

Summary

VMware Cloud Foundation 3.10.0.1 on VxRail 4.7.511 provides several features that allow existing customers to upgrade their platform more efficiently than ever before. The updated LCM capabilities offer not only more efficiency (with parallelism), but more flexibility in terms of handling the maintenance windows. With skip level upgrade, available in this version as a professional service, it’s also possible to get to this latest release much faster. This increases security, and allows customers to get the most benefit from their existing investments in the platform. New customers will benefit from the broader spectrum of hardware options, including ruggedized (D-series) and AMD-based nodes.
