Built to Scale with VCF on VxRail and Oracle 19C RAC
The newly released Oracle RAC on Dell EMC VxRail with VMware Cloud Foundations (VCF) Reference Architecture (RA) guides customers to building an efficient and high performing hyperconverged infrastructure to run their OLTP workloads. Scalability was the primary goal of this RA, and performance was highlighted as the numbers were generated. As Oracle RAC scaled, TPM increased to over 1 million TPM, while read IOPs showed sub-milli-second (0.64-0.70 ms) performance. The performance achieved with VxRail is a great added benefit to the core design points for Oracle RAC environments of which the primary focus is the availability and resiliency of the solution. Links to a reference architecture (“Oracle RAC on VMware Cloud Foundation on Dell EMC VxRail”) and a solution brief (“Deploying Oracle RAC on Dell EMC VxRail “) are available here and at the end of this post.
The RAC solution with VxRail scaled-out easily — you simply add a new node to join an existing VxRail cluster. The VxRail Manager provides a simple path that automatically discovers and non-disruptively adds each new node. VMware vSphere and vSAN can then rebalance resources and workloads across the cluster, creating a single resource pool for compute and storage.
The VxRail clusters were built with eight P570F nodes; four for the VCF Management Domain and four for the Oracle RAC Workload Domain.
Specifics on the build, including the hardware and software used, are detailed within the reference architecture. It also provides information on the testing, tools used, and results.
This graph shows the performance of TPM and Response Time when increasing the RAC node count from one to four. Notice that the average TPM increased with near-linear trendline (shown by the dotted line) as additional RAC nodes were added, while total application response time was maintained at 20 milliseconds or less.
Note: TPM near-linear trendline is shown in the above graph (blue dotted line), As additional RAC nodes are added, an increase in performance is seen as well as an increase in RAC high availability. TPM linear performance (scale equal performance per each note) growth is not achieved due to RAC nodes’ dependency on concurrency of access, instance, network, or other factors. See the RA for additional performance related information.
Summary of performance
Different-sized databases kept the TPM at the same level (about one million transactions) while keeping the application response time at 20ms or below. When increasing the database size, the physical read and write IOPS increased near-linearly, as reported from the Oracle AWR. This indicated that more read and write I/O requests were served by the backend storage, under the same configuration. Overall, when the peak client IOPS was up to 100,000, vSAN still provided excellent storage performance at sub-milliseconds at read and single-digit milliseconds latency at write.
Sidebar about Oracle licensing: While not mentioned in the RA; the VxRail offers several facilities to both control Oracle licenses and in some cases eliminates the need for costly licensed options. These include a broad choice of CPU core configurations, some with fewer cores and higher processing power per core, to maximize the customer’s Oracle workload performance while minimizing the license requirements. Costly add on options such as encryption and compression can be provided via vSAN and are handled by VxRail. Further, and the vSphere hypervisor features, like DRS, allow Oracle VMs to be contained to only licensed nodes.
You can speak to a Dell Technologies’ Oracle specialist for more details on how to control Oracle licensing costs for VMware environments.
Oracle Database 19c on VxRail offers customers performance, scalability, reliability, and security for all their operational and analytical workloads. The Oracle RAC on VxRail test environment was first created to highlight the architecture. It also had the added benefit of showcasing the great performance VxRail delivers. If you need more performance, it is simple to adjust the configuration by adding more VxRail nodes to the cluster. If you need more storage, add more drives to meet the scale required of the database. Dell Technologies has Oracle specialists to ensure the VxRail cluster will meet the scale and performance outcomes desired for Oracle environments.

The Dell Technologies Cloud Platform, VCF on VxRail, now supports the latest VxRail HCI System Software release featuring a new and improved first run experience, host geo-location tagging capabilities, hardware platform updates, and enhanced security features
Dell Technologies and VMware are happy to announce the general availability VCF 184.108.40.206 on VxRail 7.0.010.
This release brings support for the latest version of VxRail to the Dell Technologies Cloud Platform. Let’s review what these new features are all about.
Updated VxRail Software Bill of Materials
Please check out the VCF on VxRail release notes for a full listing of the supported software BOM associated with this release. You can find the link at the bottom of page.
VxRail Hardware Platform Updates
VxRail 7.0.010 brings about new support for ruggedized D-Series VxRail hardware platforms (D560/D560F). 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. To read more about the technical details of VxRail D-Series, check out the VxRail D-Series Spec Sheet.
Also, this release is reintroducing GPU support that was not in the initial VCF 4.0 on VxRail 7.0 release.
New and Improved VxRail First Run Experience
A new Day 1 VxRail cluster first run workflow and UI enhancements have been updated. The new day 1 VxRail first run deployment wizard is comprised of 13 steps or top level tasks. This day 1 workflow update was required to support new VxRail HCI System software enhancements.
The new UI provides for improved levels of configuration data entry flexibility during deployment. These options include things like allowing unique hostnames for each ESX host without forcing a name configuration, allowing for non-sequential IP addresses for hosts in the cluster, support for a geographical location ID tag, e.g. Rack Name or Rack Location are now supported. It provides a cleaner interface with a consistent look and feel for Information, Warnings, and Errors. There is improved validation, providing a higher level of feedback when errors are encountered of validation checks fail. And finally, options to manually enter all the configuration parameters or upload a pre-defined configuration via a YAML or JSON file are till available too! The figure below illustrates the new first run steps and UI.
New VxRail API to Automate Day 1 VxRail First Run Cluster Creation
This feature allows for fast and consistent VxRail cluster deployments using the programmatic extensibility of a REST API. It provides administrators with an additional option for creating VxRail clusters in addition to the VxRail Manager first run UI.
Day 1 Support to Initially Deploy Up to Six Nodes in a VxRail Cluster During VxRail First Run
The previous maximum node deployment supported in the VxRail first run was four. Administrators who needed larger VxRail cluster sizes over four nodes would have needed to create the cluster with four nodes and once that was in place, perform node expansions to get to the desired cluster size. This new feature helps reduce time needed to initially create larger VxRail clusters by allowing for a larger starting point of six VxRail nodes.
VxRail Host Geo-Location Tagging
This is probably one of the coolest and most underrated features in the release in my opinion. VxRail Manager now supports geographic location tags for VxRail hosts. This capability allows for important admin-defined host metadata that can assist many customers in gaining greater visibility of the physical location of the HCI infrastructure that makes up their cloud. This information is configured as “Host Settings” during VxRail first run as illustrated in the figure below.
As shown, the two values that make up the geo-location tags are Rack Name and Rack Position. These values are stored in the iDRAC of each VxRail host. You may be asking yourself, “Great! I have the ability to add additional metadata for my VxRail hosts but what can I do with it?”. Well, together, these values help a cloud administrator identify a VxRail host’s position within a given rack within the data center. Cloud administrators can then leverage this data to choose the VxRail host order they want to be displayed in the VxRail Manager vCenter plugin Physical View. The figure below illustrates what this would look like.
As datacenter environments grow, VxRail host expansion operations can be used to add additional infrastructure capacity. The VxRail “Add VxRail Hosts” automated expansion workflows have been updated to include a new Host Location step which allows for the ability add geo-location Rack Name and Rack Position metadata for the new hosts being added to an existing VxRail Cluster. The figure below shows what a host expansion operation would look like.
In this fast paced world of digital transformation, it is not uncommon for cloud datacenter infrastructure to be moved within a datacenter after it has already been installed. This could be due to physical rack expansion design changes or infrastructure repurposing. These situations were also considered with using VxRail geo-location tags. Thus, there is an option to dynamically edit an existing host’s geo-location information. When this is performed, VxRail Manager will automatically update the host’s iDRAC with the new values. The figure below shows what the host edit would look like.
All these geo-location management capabilities provide VCF on VxRail administrators with full stack physical to virtual infrastructure mapping that help further extend the Cloud Foundation management experience and simplify operations! And this capability is only available with the Dell Technologies Cloud Platform (VCF on VxRail)! How cool is that?!
VxRail Security Enhancements
Added Security Compliance With The Addition of FIPS 140-2 Level 1 Validated Cryptography For VxRail Manager
Cloud Foundation on VxRail offers intrinsic security built into every layer of the solution stack, from hardware silicon to storage to compute to networking to governance controls. This helps customers make security a built part of the platform for your traditional workloads as well as container based cloud native workloads rather than something that is bolted on after the fact.
Building on the intrinsic security capabilities of the platform are the following new features:
VxRail Manager is now FIPS 140-2 compliant, offering built-in intrinsic encryption, meeting the high levels of security standards required by the US Department of Defense.
From VxRail 7.0.010 onward, VxRail has ‘FIPS inside’! This would entail having built-in features such as:
- VxRail Manager Data-in-Transit (e.g., HTTPS interfaces, SSH)
- VxRail Manager's SLES12 FIPS usage
- VxRail Manager - encryption used for password caching
Disable VxRail LCM operations from vCenter
In order to limit administrator configuration error by allowing for the performing of VxRail LCM operations from within vCenter rather than through SDDC Manager, all VCF on VxRail deployments will natively lockdown the vSphere Web Client VxRail Manager Plugin Updates screen out of the box. This enforces administrators to use SDDC Manager for all LCM operations which will guarantee that the full stack of HW/SW used have all been qualified and validated for their environment. The figure below illustrates what this looks like.
Disable VxRail Host Rename/Re-IP operations in vCenter
Continuing with the idea of trying to limit administration configuration errors, this feature deals with trying to avoid configuration errors by not allowing administrators to perform VxRail Host Edit operations from within vCenter that are not supported in VCF. This helps maintain an operating experience in which all VCF on VxRail deployments will natively lockdown the vSphere Web Client VxRail Manager Plugin Hosts screen out of the box. The figure below illustrates what this looks like
Now those are some intrinsic security features!
Well that about covers all the new features! Thanks for taking the time to learn more about this latest release. As always, check out some of the links at the bottom of this page to access additional VCF on VxRail resources.

The latest Dell Technologies Cloud Platform release introduces new support for vSphere with Kubernetes for entry cloud deployments and more
Dell Technologies and VMware are happy to announce the general availability VCF 4.0.1 on VxRail 7.0.
This release offers several enhancements including vSphere with Kubernetes support for entry cloud deployments, enhanced bring up features for more extensibility and accelerated deployments, increased network configuration options, and more efficient LCM capabilities for NSX-T components. Below is the full listing of features that can be found in this release:
- Kubernetes in the management domain: vSphere with Kubernetes is now supported in the management domain. With VMware Cloud Foundation Workload Management, you can deploy vSphere with Kubernetes on the management domain default cluster starting with only four VxRail nodes. This means that DTCP entry cloud deployments can take advantage of running Kubernetes containerized workloads alongside general purpose VM workloads on a common infrastructure!
- Multi-/multi- during VCF bring-up: The Cloud Builder deployment parameter workbook now provides five vSphere Distributed Switch () profiles that allow you to perform bring-up of hosts with two, four, or six physical NICs () and to create up to two vSphere Distributed Switches for isolating system (Management, , ) traffic from overlay (Host, Edge, and Uplinks) traffic.
- Multi-/multi- API support: The VCF API now supports configuring a second vSphere Distributed Switch () using up to four physical NICs (), providing more flexibility to support high performance use cases and physical traffic separation.
- NSX-T cluster-level upgrade support: Users can upgrade specific host clusters within a workload domain so that the upgrade can fit into their maintenance windows bringing about more efficient upgrades.
- Cloud Builder API support for bring-up operations – VCF on VxRail deployment workflows have been enhanced to support using a new Cloud Builder API for bring-up operations. VCF software installation on VxRail during VCF bring-up can now be done using either an API or GUI providing even more platform extensibility capabilities.
- Automated externalization of the vCenter Server for the management domain: Externalizing the vCenter Server that gets created during the VxRail first run (the one used for the management domain) is now automated as part of the bring-up process. This enhanced integration between the VCF Cloud Builder bring-up automation workflow and VxRail API helps to further accelerate installation times for VCF on VxRail deployments.
- BOM Updates: Updated VCF software Bill of Materials with new product versions.
