VMware Cloud Foundation Software Feature Updates

VCF on VxRail Management Enhancements

vSphere Cluster Level Services (vCLS)

vSphere Cluster Services is a new capability introduced in the vSphere 7 Update 1 release that is included as a part of VCF 4.1. It runs as a set of virtual machines deployed on top of every vSphere cluster. Its initial functionality provides foundational capabilities that are needed to create a decoupled and distributed control plane for clustering services in vSphere. vCLS ensures cluster services like vSphere DRS and vSphere HA are all available to maintain the resources and health of the workloads running in the clusters independent of the availability of vCenter Server. The figure below shows the components that make up vCLS from the vSphere Web Client.

Figure 1

Not only is vSphere 7 providing modernized data services like embedded vSphere Native Pods with vSphere with Tanzu but features like vCLS are now beginning the evolution of modernizing to distributed control planes too! 

VCF Managed Resources and VxRail Cluster Object Renaming Support

VCF can now rename resource objects post creation, including the ability to rename domains, datacenters, and VxRail clusters.

The domain is managed by the SDDC Manager. As a result, you will find that there are additional options within the SDDC Manager UI that will allow you to rename these objects. 

VxRail Cluster objects are managed by a given vCenter server instance. In order to change cluster names, you will need to change the name within vCenter Server. Once you do, you can go back to the SDDC Manager and after a refresh of the UI, the new cluster name will be retrieved by the SDDC Manager and shown.

In addition to the domain and VxRail cluster object rename, SDDC Manager now supports the use of a customized Datacenter object name. The enhanced VxRail VI WLD creation wizard process has been updated to include inputs for Datacenter Name and is automatically imported into the SDDC Manager inventory during the VxRail VI WLD Creation SDDC Manager workflow. Note: Make sure the Datacenter name matches the one used during the VxRail Cluster First Run. The figure below shows the Datacenter Input step in the enhanced VxRail VI WLD creation wizard from within SDDC Manager.

Figure 2

Being able to customize resource object names makes VCF on VxRail more flexible in aligning with an IT organization’s naming policies.

VxRail Integrated SDDC Manager WLD Cluster Node Removal Workflow Optimization

Furthering the Dell Technologies and VMware co-engineering integration efforts for VCF on VxRail, new workflow optimizations have been introduced in VCF 4.1 that take advantage of VxRail Manager APIs for VxRail cluster host removal operations.

 When the time comes for VCF on VxRail cloud administrators to remove hosts from WLD clusters and repurpose them for other domains, admins will use the SDDC Manager “Remove Host from WLD Cluster” workflow to perform this task. This remove host operation has now been fully integrated with native VxRail Manager APIs to automate removing physical VxRail hosts from a VxRail cluster as a single end-to-end automated workflow that is kicked off from the SDDC Manager UI or VCF API. This integration further simplifies and streamlines VxRail infrastructure management operations all from within common VMware SDDC management tools. The figure below illustrates the SDDC Manager sub tasks that include new VxRail API calls used by SDDC Manager as a part of the workflow.

 Figure 3

 Note: Removed VxRail nodes require reimaging prior to repurposing them into other domains. This reimaging currently requires Dell EMC support to perform.

I18N Internationalization and Localization (SDDC Manager)

SDDC Manager now has international language support that meets the I18N Internationalization and Localization standard. Options to select the desired language are available in the Cloud Builder UI, which installs SDDC Manager using the selected language settings. SDDC Manager will have localization support for the following languages – German, Japanese, Chinese, French, and Spanish. The figure below illustrates an example of what this would look like in the SDDC Manager UI.

Figure 4

vRealize Suite Enhancements 

VCF Aware vRSLCM

New in VCF 4.1, the vRealize Suite is fully integrated into VCF. The SDDC Manager deploys the vRSLCM and creates a two way communication channel between the two components. When deployed, vRSLCM is now VCF aware and reports back to the SDDC Manager what vRealize products are installed. The installation of vRealize Suite components utilizes built standardized VVD best practices deployment designs leveraging Application Virtual Networks (AVNs).

Software Bundles for the vRealize Suite are all downloaded and managed through the SDDC Manager. When patches or updates become available for the vRealize Suite, lifecycle management of the vRealize Suite components is controlled from the SDDC Manager, calling on vRSLCM to execute the updates as part of SDDC Manager LCM workflows. The figure below showcases the process for enabling vRealize Suite for VCF.

 Figure 5

VCF Multi-Site Architecture Enhancements

VCF Remote Cluster Support

VCF Remote Cluster Support enables customers to extend their VCF on VxRail operational capabilities to ROBO and Cloud Edge sites, enabling consistent operations from core to edge. Pair this with an awesome selection of VxRail hardware platform options and Dell Technologies has your Edge use cases covered. More on hardware platforms later…For a great detailed explanation on this exciting new feature check out the link to a detailed VMware blog post on the topic at the end of this post.

VCF LCM Enhancements

NSX-T Edge and Host Cluster-Level and Parallel Upgrades

With previous VCF on VxRail releases, NSX-T upgrades were all encompassing, meaning that a single update required updates to all the transport hosts as well as the NSX Edge and Manager components in one evolution.

With VCF 4.1, support has been added to perform staggered NSX updates to help minimize maintenance windows. Now, an NSX upgrade can consist of three distinct parts:

• Updating of edges
  1. Can be one job or multiple jobs. Rerun the wizard.
  2. Must be done before moving to the hosts
• Updating the transport hosts
• Once the hosts within the clusters have been updated, the NSX Managers can be updated.

Multiple NSX edge and/or host transport clusters within the NSX-T instance can be upgraded in parallel.  The Administrator has the option to choose some clusters without having to choose all of them. Clusters within a NSX-T fabric can also be chosen to be upgraded sequentially, one at a time. Below are some examples of how NSX-T components can be updated.

NSX-T Components can be updated in several ways. These include updating:

• NSX-T Edges and Host Clusters within an NSX-T instance can be upgraded together in parallel (default) 
• NSX-T Edges can be upgraded independently of NSX-T Host Clusters
• NSX-T Host Clusters can be upgraded independently of NSX-T Edges only after the Edges are upgraded first
• NSX-T Edges and Host Clusters within an NSX-T instance can be upgraded sequentially one after another.

The figure below visually depicts these options.

 Figure 6

These options provide Cloud admins with a ton of flexibility so they can properly plan and execute NSX-T LCM updates within their respective maintenance windows. More flexible and simpler operations. Nice! 

VCF Security Enhancements

Read-Only Access Role, Local and Service Accounts

A new ‘view-only’ role has been added to VCF 4.1. For some context, let’s talk a bit now about what happens when logging into the SDDC Manager. 

First, you will provide a username and password. This information gets sent to the SDDC Manager, who then sends it to the SSO domain for verification. Once verified, the SDDC Manager can see what role the account has privilege for. 

In previous versions of Cloud Foundation, the role would either be for an Administrator or it would be for an Operator. 

 Now, there is a third role available called a ‘Viewer’. Like its name suggests, this is a view only role which has no ability to create, delete, or modify objects. Users who are assigned this role may not see certain items in the SDDC Manger UI, such as the User screen. They may also see a message saying they are unauthorized to perform certain actions.

 Also new, VCF now has a local account that can be used during an SSO failure. To help understand why this is needed let’s consider this: What happens when the SSO domain is unavailable for some reason? In this case, the user would not be able to login. To address this, administrators now can configure a VCF local account called admin@local. This account will allow the performing of certain actions until the SSO domain is functional again. This VCF local account is defined in the deployment worksheet and used in the VCF bring up process. If bring up has already been completed and the local account was not configured, then a warning banner will be displayed on the SDDC Manager UI until the local account is configured.

Lastly, SDDC Manager now uses new service accounts to streamline communications between SDDC manager and the products within Cloud Foundation. These new service accounts follow VVD guidelines for pre-defined usernames and are administered through the admin user account to improve inter-VCF communications within SDDC Manager.

VCF Data Protection Enhancements

 As described in this blog, with VCF 4.1, SDDC Manager backup-recovery workflows and APIs have been improved to add capabilities such as backup management, backup scheduling, retention policy, on-demand backup & auto retries on failure. The improvement also includes Public APIs for 3rd party ecosystem and certified backup solutions from Dell PowerProtect.

VxRail Software Feature Updates

VxRail Networking Enhancements

VxRail 4 x 25Gbps pNIC redundancy

VxRail engineering continues innovate in areas that drive more value to customers. The latest VCF on VxRail release follows through on delivering just that for our customers. New in this release, customers can use the automated VxRail First Run Process to deploy VCF on VxRail nodes using 4 x 25Gbps physical port configurations to run the VxRail System vDS for system traffic like Management, vSAN, and vMotion, etc. The physical port configuration of the VxRail nodes would include 2 x 25Gbps NDC ports and additional 2 x 25Gbps PCIe NIC ports.

In this 4 x 25Gbps set up, NSX-T traffic would run on the same System vDS. But what is great here (and where the flexibility comes in) is that customers can also choose to separate NSX-T traffic on its own NSX-T vDS that uplinks to separate physical PCIe NIC ports by using SDDC Manager APIs. This ability was first introduced in the last release and can also be leveraged here to expand the flexibility of VxRail host network configurations.

The figure below illustrates the option to select the base 4 x 25Gbps port configuration during VxRail First Run.

Figure 7

By allowing customers to run the VxRail System VDS across the NDC NIC ports and PCIe NIC ports, customers gain an extra layer of physical NIC redundancy and high availability. This has already been supported with 10Gbps based VxRail nodes. This release now brings the same high availability option to 25Gbps based VxRail nodes. Extra network high availability AND 25Gbps performance!? Sign me up!

VxRail Hardware Platform Updates

Recently introduced support for ruggedized D-Series VxRail hardware platforms (D560/D560F) continue expanding the available VxRail hardware platforms supported in the Dell Technologies Cloud Platform. 

These ruggedized and durable platforms are designed to meet the demand for more compute, performance, storage, and more importantly, operational simplicity that deliver the full power of VxRail for workloads at the edge, in challenging environments, or for space-constrained areas. 

These D-Series systems are a perfect match when paired with the latest VCF Remote Cluster features introduced in Cloud Foundation 4.1.0 to enable Cloud Foundation with Tanzu on VxRail to reach these space-constrained and challenging ROBO/Edge sites to run cloud native and traditional workloads, extending existing VCF on VxRail operations to these locations! Cool right?!

To read more about the technical details of VxRail D-Series, check out the VxRail D-Series Spec Sheet.

Well that about covers it all for this release. The innovation train continues. Until next time, feel free to check out the links below to learn more about DTCP (VCF on VxRail).

Underlying HCI infrastructure architecture considerations

As many organizations embrace digital transformation and the application modernization journey that is involved in this process, Dell Technologies and VMware supporting customers by providing them with modern cloud infrastructure and storage solutions that support the demands of this new set of cloud native applications.

Dell ObjectScale, VMware vSphere with Tanzu, and the vSAN Data Persistence Platform (vDPp) are all examples of next generation cloud native technologies that deliver simple, scalable, and enterprise grade Kubernetes native S3 compatible object storage services on a Kubernetes runtime built into the vSphere hypervisor. To learn more about the details of this powerful set of technologies, check out these great blog posts from my colleagues over at VMware here and here. A recently published reference architecture white paper also walks through the steps of deploying these technologies together. 

Now let’s get into our primary topic for this blog, which is the underlying HCI infrastructure architecture considerations for running ObjectScale on vSphere with Tanzu. 

Setting the stage

Cloud infrastructure administrators have a lot of flexibility in terms of what and how to configure the infrastructure on which Dell ObjectScale runs. These options not only come at the underlying HCI infrastructure implementation layer but also at the VMware SDDC layer. This gives administrators choices on mixing the right combination of the two layers that best meet their business and operational requirements.

So, what are the layers that make up these options? For this discussion we will break it down as follows:

HCI Infrastructure Layer Options

• Construct – Dell vSAN Ready Nodes
• Consume – Dell VxRail HCI Integrated Systems

VMware SDDC Software Layer Options

• 
  

  Construct - VMware vSphere with Tanzu + VMware NSX-T
• Consume - VMware Cloud Foundation (VCF) with Tanzu

After we review these options, we will highlight how they can be used to align to your ObjectScale architecture design and workload requirements.

Construct HCI and Construct VMware SDDC – Dell ObjectScale on Dell vSAN Ready Nodes with VMware vSphere with Tanzu + VMware NSX-T

This option involves deploying ObjectScale on vSphere with Tanzu enabled Dell vSAN Ready Node clusters and then manually deploying and configuring the rest of the required VMware SDDC software stack including NSX-T. This is essentially the builder’s approach to implementing the HCI infrastructure stack and the VMware SDDC stack. This gives infrastructure administrators the most control over their infrastructure configuration and components. The tradeoff, however, is that it adds a bit more complexity and more manual steps to get to an outcome that is ObjectScale ready.

Consume HCI and Construct VMware SDDC – Dell ObjectScale on Dell VxRail with VMware vSphere with Tanzu + VMware NSX-T

 With this approach, infrastructure administrators can take advantage of consuming pre-validated and co-engineered Dell VxRail HCI integrated systems, enabling vSphere with Tanzu on them, and then manually deploying the NSX-T components of the solution. This speeds up and simplifies the HCI infrastructure management and operations portion of the stack while still delivering on the required SDDC infrastructure foundations needed for ObjectScale to run.

Construct HCI and Consume VMware SDDC – Dell ObjectScale on VMware Cloud Foundation with Tanzu on Dell vSAN Ready Nodes

 This option delivers infrastructure administrators with granular control in constructing the underlying HCI HW components while simplifying the VMware SDDC layer and consuming it as a full cloud platform using VMware Cloud Foundation. This helps streamline the VMware SDDC to include NSX-T out of the box and can automate the deployment and configuration of the VMware SDDC components that are required to enable vSphere with Tanzu and run ObjectScale.

Consume HCI and Consume VMware SDDC – Dell ObjectScale on VMware Cloud Foundation with Tanzu on Dell VxRail

 This option provides a true full stack turnkey cloud infrastructure platform for infrastructure administrators to consume. This co-engineered solution between VMware and Dell Technologies delivers the fastest path to hybrid cloud and Kubernetes. Administrators gain the operational and feature benefits of VxRail, the only HCI system with deep VMware Cloud Foundation integration, with the out of the box simplicity and automation of the VMware Cloud Foundation SDDC cloud platform. From an ObjectScale use case perspective, infrastructure administators can accelerate getting all the needed underlying cloud infrastructure up and running so that ObjectScale can be deployed quickly and easily at scale and with a standardized cloud infrastructure architecture built in.

Choosing the right ObjectScale deployment infrastructure architecture

All these options deliver the necessary infrastructure prerequisites required to deploy and run ObjectScale, just through different implementation approaches that align to an organization’s operating model. ObjectScale, however, can also be deployed in several different ways, which can affect the implementation of your underlying infrastructure. 

 Let’s review what these options are, how our infrastructure can support these deployment models, and when would be the best time to choose one over the other.

 First, let’s call out the ObjectScale deployment architecture options available:

1. Co-locate ObjectScale data services on the same clusters where user application workloads run
2. Run ObjectScale data services on dedicated cluster infrastructure separate from user application workloads

How an infrastructure administrator would configure the underlying HCI and VMware SDDC stack based on these options will ultimately depend on which SDDC deployment method was used, vSphere with Tanzu + NSX-T or VCF with Tanzu.

The infrastructure implementation design details vary slightly since VCF implements a prescriptive cloud architecture using the concept of workload domains. This means that cloud infrastructure administrators must consider how to deploy vSphere with Tanzu enabled clusters to run ObjectScale within the context of this VCF’s workload domain architecture. On the other hand, if administrators were using the build approach of deploying individual vSphere with Tanzu enabled clusters, architecture design decisions are a bit more open ended. Either way, both implementation methods support both ObjectScale deployment architecture models of co-located and dedicated and can be run on both Dell vSAN Ready Nodes and Dell VxRail HCI Integrated Systems.

So, what would the first option look like when co-locating ObjectScale data services on the same cluster as where user application workloads are run?

The following figure provides a visual depiction of what this option may look like in a VCF on VxRail deployment using a single VI workload domain with a single vSphere with Tanzu enabled VxRail cluster in it. In this example, we would deploy ObjectScale to the Supervisor Cluster running on this WLD cluster. Application teams would then have their user application workloads running on the same cluster infrastructure and share the underlying physical HCI compute, network, and storage resources. 

 Figure 1: VCF on VxRail – ObjectScale co-location cluster deployment

This approach has advantages in terms of minimizing the infrastructure footprint required to run both workload types. It can also help drive improved resource utilization of the HCI infrastructure that has been deployed. This can also be a great fit for minimizing licensing costs if you have containerized user workloads and VM-based workloads that need to consume ObjectScale storage since there is only one cluster you need to enable vSphere with Tanzu on and vSphere can support running containers and VMs on the same vSphere cluster. However, there are possible downsides. These include resource contention for user workloads since you are sharing the same infrastructure to run ObjectScale data services and lack of independent scalability and right sizing of infrastructure resources for ObjectScale and the user applications.  

Option 2, running ObjectScale data services on dedicated cluster infrastructure separate from user application workloads, eliminates the resource contention by running ObjectScale on its own dedicated cluster infrastructure separate from user workloads. In a VCF on VxRail deployment, this may be implemented in a couple of ways. The first is to create a single VI WLD with two or more VxRail clusters in it. One cluster would have vSphere with Tanzu enabled on it and is where ObjectScale would be deployed. The other cluster, depending on the types of workloads running (whether they be VM-based only or a mix of containers and VMs) may not require vSphere with Tanzu be enabled on it and can just be used to run user application workloads.

By running ObjectScale on its own workload domain cluster resources, we now have physical resource isolation for both ObjectScale and user application workloads. This avoids resource contention between the two and now have the flexibility to independently scale resources for both as needed. Using this VCF workload domain organizational model may be helpful if your organization is aligning ObjectScale storage and the workloads that consume it as part of a single business unit and you may want to keep all of that together and managed within a single managed pool of cloud infrastructure resources. The following diagram provides an illustration of how this would look. 

 Figure 2: VCF on VxRail – ObjectScale dedicated cluster deployment with single VI WLD

The other VCF workload domain design approach is to deploy two VI workload domains. One would contain one or more VxRail clusters with vSphere with Tanzu enabled on them and ObjectScale would be deployed on top. The other VI workload domain would contain one or more VxRail clusters that may or may not have vSphere with Tanzu enabled on them and would run user application workloads only. This method still gets you separation of physical resources to avoid resource contention as well as independent scaling for both workload types, but organizationally we have deployed workload domains based on infrastructure service function. 

Deploying ObjectScale into its own dedicated workload domain provides the possibility of maximum scale of how many clusters we can deploy into a single domain that can be used solely for running ObjectScale data services. We can also help simplify the networking for those clusters since we only need to accommodate for the networking needs of ObjectScale and not also for user applications workloads, too. 

The following example uses dedicated NSX-T instances for each VI workload domain. In VCF, it is possible to share an NSX-T instance across multiple VI workload domains. If we would have done this, we wouldn’t have to deploy another cluster of NSX Edge appliances and could have just used the NSX Edge appliance deployed in VI Workload Domain 2 to meet the requirements that are needed when enabling vSphere with Tanzu on vSphere clusters. But since we are using separate dedicated NSX-T instances, each VI workload domain will require NSX Edge appliances to meet these vSphere with Tanzu and ObjectScale minimum requirements for the clusters contained within them. The following figure shows an illustration of what this multi-workload domain organizational model would look like. 

Figure 3: VCF on VxRail – ObjectScale dedicated cluster deployment with two VI WLDs

It is important to call out that these same co-located and dedicated cluster ObjectScale architecture models can be used in vSphere with Tanzu + NSX-T on Dell vSAN Ready Nodes/VxRail deployment options as well and are not tied to just the VCF on VxRail examples shown here. The same overall ObjectScale logical and physical layout considerations would apply. Administrators who choose to approach running ObjectScale in this way would be responsible for determining where the NSX-T Manager VM’s, Edge appliances, and vCenter components would run as there would be no Management Domain construct defined as part of a cloud platform architecture like VCF has.

This is not the end, it’s just the beginning…

I hope you have found this information helpful as you work through your ObjectScale adoption journey. This is not the end of your journey, however. For more information about VxRail and ObjectScale, check out the links at the bottom of this post.
