Like any good techie, I can get a little obsessed with gadgets that improve my quality of life. Take, for example, my recent discovery of wearable technology that eases the symptoms of motion sickness. For most of my life, I’ve had to take over-the-counter or prescription medicine when boating, flying, and going on road trips. Then, I stumbled across a device that I could wear around my wrist that promised to solve the problem without the side effects. Hesitantly, I bought the device and asked a friend to drive like a maniac around town while I sat in the back seat. It actually worked – no headache, no nausea, and no grogginess from meds! Needless to say, I never leave home without my trusty gizmo to keep motion sickness at bay.
Throughout my career in managing IT infrastructure, stress has affected my quality of life almost as much as motion sickness. There is one responsibility that has always caused more angst than anything else: lifecycle management (LCM). To narrow that down a bit, I’m specifically talking about patching and updating IT systems under my control. I have sometimes been derelict in my duties because of annoying manual steps that distract me from working on the fun, highly visible projects. It’s these manual steps that can cause the dreaded DU/DL (data unavailable or data loss) to rear its ugly head. Can you say insomnia?
Innovative technology to the rescue once again! While creating a demo video last year for our Dell EMC OpenManage Integration with Microsoft Windows Admin Center (OMIMSWAC), I was blown away by how easy we made the BIOS, firmware, and driver updates on clusters. The video did a pretty good job of showing the power of the Cluster-Aware Updating (CAU) feature, but it didn’t go far enough. I needed to quantify its full potential to change an IT profressional’s life by pitting an OMIMSWAC’s automated, CAU approach against a manual, node-based approach. I captured the results of the bake off in Dell EMC HCI Solutions for Microsoft Windows Server: Lifecycle Management Approach Comparison.
Automation Triumphs!
For this white paper to really stand the test of time, I knew I needed to be very clever to compare apples-to-apples. First, I referred to HCI Operations Guide—Managing and Monitoring the Solution Infrastructure Life Cycle, which detailed the hardware updating procedures for both the CAU and node-based approaches. Then, I built a 4-node Dell EMC HCI Solutions for Windows Server 2019 cluster, performed both update scenarios, and recorded the task durations. We all know that automation is king, but I didn’t expect the final tally to be quite this good:
- The automated approach reduced the number of steps in the process by 82%.
- The automated approach required 90% less of my focused attention. In other words, I was able to attend to other duties while the updates were installing.
- If I was in a production environment, the maintenance window approved by the change control board would have been cut in half.
- The automated process left almost no opportunity for human error.
As you can see from the following charts taken from the paper, these numbers only improved as I extrapolated them out to the maximum Windows Server HCI cluster size of 16 nodes.
I thought these results were too good to be true, so I checked my steps about 10 times. In fact, I even debated with my Marketing and Product Management counterparts about sharing these claims with the public! I could hear our customers saying, “Oh, yeah, right! These are just marketecture hero numbers.” But in this case, I collected the hard data myself. I am still confident that these results will stand up to any scrutiny. This is reality – not dreamland!
Just when I thought it couldn’t get any better
So why am I blogging about a project I did last year? Just when I thought the testing results in the white paper couldn’t possibly get any better, Dell EMC Integrated System for Microsoft Azure Stack HCI came along. Azure Stack HCI is Microsoft’s purpose-built operating system delivered as an Azure service. The current release when writing this blog was Azure Stack HCI, version 20H2. Our Solution Brief provides a great overview of our all-in-one validated HCI system, which delivers efficient operations, flexible consumption models, and end-to-end enterprise support and services. But what I’m most excited about are two lifecycle management enhancements – 1-click full stack LCM and Kernel Soft Reboot – that will put an end to the old adage, “If it looks too good to be true, it probably is.”
Let’s invite OS updates to the party
OMIMSWAC was at version 1.1 when I did my testing last year. In that version, the CAU feature focused on the hardware – BIOS, firmware, and drivers. In OMIMSWAC v2.0, we developed an exclusive snap-in to Microsoft’s Failover Cluster Tool Extension to create 1-click full stack LCM. Only available for clusters running Azure Stack HCI, a simple workflow in Windows Admin Center automates not only the hardware updates – but also the operating system updates. How do I see this feature lowering my blood pressure?
- Applying the OS and hardware updates can typically require multiple server reboots. With 1-click full stack LCM, reboots are delayed until all updates are installed. A single reboot per node in the cluster results in greater time savings and shorter maintenance windows.
- I won’t have to use multiple tools to patch different aspects of my infrastructure. The more I can consolidate the number of management tools in my environment, the better.
- A simple, guided workflow that tightly integrates the Microsoft extension and OMIMSWAC snap-in ensures that I won’t miss any steps and provides one view to monitor update progress.
- The OMIMSWAC snap-in provides necessary node validation at the beginning of the hardware updates phase of the workflow. These checks verify that my cluster is running validated AX nodes from Dell Technologies and that all the nodes are homogeneous. This gives me peace of mind knowing that my updates will be applied successfully. I can also rest assured that there will be no interruption to the workloads running in my VMs and containers since this feature leverages CAU.
- The hardware updates leverage the Microsoft HCI solution catalog from Dell Technologies. Each BIOS, firmware, and driver in this catalog is validated by our engineering team to optimize the Azure Stack HCI experience.
The following screen shots were taken from the full stack CAU workflow. The first step indicates which OS updates are available for the cluster nodes.
Node validation is performed first before moving forward with hardware updates.
If the Windows Admin Center host is connected to the Internet, the online update source approach obtains all the systems management utilities and the engineering validated solution catalog automatically. If operating in an edge or disconnected environment, the solution catalog can be created with Dell EMC Repository Manager and placed on a file server share accessible from the cluster nodes.
The following image shows a generated compliance report. All non-compliant components are selected by default for updating. After this point, all the OS and non-compliant hardware components will be updated together with only a single reboot per node in the cluster and with no impact to running workloads.
Life is too short to wait for server reboots
Speaking of reboots, Kernel Soft Reboot (KSR) is a new feature coming in Azure Stack HCI, version 21H2 that also has the potential to make my white paper claims even more jaw dropping. KSR will give me the ability to perform a “software-only restart” on my servers – sparing me from watching the paint dry during those long physical server reboots. Initially, the types of updates in scope will be OS quality and security hotfixes since these don’t require BIOS/firmware initialization. Dell Technologies is also working on leveraging KSR for the infrastructure updates in a future release of OMIMSWAC.
KSR will be especially beneficial when using Microsoft’s CAU extension in Windows Admin Center. The overall time savings using KSR multiplies for clusters because faster restarts means less resyncing of data after CAU resumes each cluster node. Each node should reboot with Mach Speed if there are only Azure Stack HCI OS hotfixes and Dell EMC Integrated System infrastructure updates that do not require the full reboot. I will definitely be hounding my Product Managers and Engineering team to deliver KSR for infrastructure updates in our OMIMSWAC extension ASAP.
Bake off rematch
I decided to hold off on doing a new bakeoff until Azure Stack HCI, version 21H2 is released with KSR. I also want to wait until we bring the benefits of KSR to OMIMSWAC for infrastructure updates. The combination of OMIMSWAC 1-click full stack CAU and KSR will continue to make OMIMSWAC unbeatable for seamless lifecycle management. This means better outcomes for our organizations, improved blood pressure and quality of life for IT pros, and more motion-sickness-free adventure vacations. I’m also looking forward to spending more time learning exciting new technologies and less time with routine administrative tasks.

Windows Admin Center extensions and integrations
You can install Microsoft Cluster Aware Updating extension within WAC by selecting the “Gear” icon on the top right corner, then under “Gateway”, navigate to “Extensions”. Under “Available extensions”, find the desired extension and select “Install”. For details, see the install guide. Please refer to the extensions product documentation for the latest updates.
Microsoft Cluster Aware Updating extension
To get to Microsoft WAC Azure Stack HCI Cluster Aware Updating extension, login to WAC and follow these steps:
- Click on the cluster you want to connect to. This takes us to the cluster Dashboard.
- On the left pane, under “Tools”, select “Update”.
- In the “Updates” window, click on “Check for updates”, which will pop up the “Install updates” window.
- Here we are presented with a three-step process where we select, in order:
- Operating system updates
- Hardware updates
- Proceed with the installation
It is important to note that you can select either to run only one operation at a time by skipping the other or run both in one single process and reboot.
You may select, if available, any Operating system update and click “Next: Hardware updates”. 
This takes us to the second step of the sequence - Hardware updates - a key phase for the automated end-to-end cluster aware update process.
This is where the Dell Technologies snap-in integrates with Microsoft’s original workflow, allowing us to seamlessly provide automated BIOS, firmware, and driver updates (and OS updates if also selected) to all the nodes in the cluster with a single reboot. Let’s look at this process in detail in the next section.
Dell EMC Integrated Full Stack Cluster Aware Updating
Once you click “Next: Hardware updates” on the original Microsoft’s Azure Stack HCI Cluster Aware Updating workflow, you are taken to Dell EMC Cluster Aware Updating integration.
If the integration is not installed, there is an option to install it from inside the workflow.
Click “Get updates”.
Our snap-in for Cluster Aware Updating (CAU) takes us through the following sequence of five steps.
1. Prerequisites (screenshot above)
A validation process occurs, checking that all AX nodes are:
- Supported in the HCL
- Same model
- OpenManage Premium License for MSFT HCI Solutions compliant (included in AX node base solution)
- Compatible with cluster creation
Click “Next: Update source”.
2. Update source
Here we can select the source for our BIOS, firmware, and driver repository, whether online [Update Catalog for Microsoft HCI Solutions] or offline (edge or disconnected) [Dell EMC Repository Manager Catalog]. Dell Technologies has created and keeps these solution catalogs updated.
Click “Next: Compliance report”.
3. Compliance report
Now we can check how compliant our nodes are and select for BIOS, firmware, and/or driver remediation. All the recommended components are selected by default.
The compliance operation runs in parallel for all nodes, and the report is shown consolidated across nodes.
Click “Next: Summary”.
4. Summary
All selections from all nodes are shown in Summary for review before we click “Next: Download updates”.
5. Download updates
This window provides the statistics regarding the download process (start time, download status).
When all downloads are completed, we can click “Next: Install”, which takes us back again to Step 3 of the main workflow (“Install”), to begin the installation process of OS and hardware updates (if both were selected) on the target nodes.
If any of the updates requires a restart, servers will be rebooted one at a time, moving cluster roles such as VMs between servers to prevent downtime and guaranteeing business continuity.
Once the process is finished for all the nodes, we can go back to “Updates” to check for the latest update status and/or Update history for previous updates.
It is important to note that the Cluster Aware Updating extension is supported only for Dell EMC Integrated System for Microsoft Azure Stack HCI.
OMIMSWAC v2.0 Standalone extension
The standalone extension applies to Windows Server HCI and Azure Stack HCI, and continues to provide monitoring, inventory, troubleshooting, and hardware updates with CAU.
New to OMIMSWAC 2.0 is the option to schedule updates during a programmed maintenance window for greater flexibility and control during the update process.
It is important to note that OMIMSWAC Standalone version provides the Cluster Aware Updating feature for the hardware (BIOS, firmware, drivers) in a single reboot, although this process is not integrated with operating system updates. It provides full lifecycle management just for the hardware, not the OS layer.
Another key takeaway is that OMIMSWAC Standalone version fully supports Dell EMC HCI Solutions from Microsoft Windows Server and even certain qualified previous solutions (Dell EMC Storage Spaces Direct Ready Nodes).
Conclusion
Dell Technologies has developed OMIMSWAC to make integrated systems’ lifecycle management a seamless and easy process. It can fully guarantee controlled end-to-end cluster hardware and software update processes during the lifespan of the service.
The Dell EMC OMIMSWAC automated and programmatic approach provides obvious benefits, like mitigating risk caused by human intervention, significantly fewer steps to update clusters, and significantly less focused attention time for IT administrators. In small 4-node cluster deployments, this can mean up to 80% fewer steps and up to 90% less focused attention from an IT operator.
Full details on the benefits of performing these operations automatically through OMIMSWAC versus doing it manually are explained in this white paper.

Break through performance barriers
If your organization is on the road to infrastructure modernization, chances are good that your underlying legacy virtualization clusters are being stretched to their limits. This could mean suboptimal performance and resiliency, which can make it difficult to scale clusters and meet service-level agreements (SLAs).
In addition, with overtaxed and aging clusters, you can’t virtualize applications that you would like to because of performance requirements, which can mean a larger data center footprint and higher corresponding power and cooling costs.
If you’re thinking about refreshing and modernizing your legacy virtualization environments, you might want to consider a Dell EMC Integrated System for Microsoft Azure Stack HCI.
Solution overview
This all-in-one validated hyperconverged infrastructure (HCI) solution includes full-stack lifecycle management, native integration into Microsoft Azure, flexible consumption models and solution-level enterprise support and services expertise. Dell EMC Integrated System for Azure Stack HCI is available in a broad range of configurations, and it include engineering-validated AX nodes and networking topologies with Dell EMC PowerSwitch network switches. This design and validation can help ensure that every component—including firmware and driver versions—is optimized for demanding workloads.
Dell Technologies performed synthetic workload testing on one of these systems to see how it performed with highly demanding real-world application profiles. The cluster included four AX-7525 nodes, each populated with two 64-core AMD EPYC™ 7742 processors, 24 NVM Express (NVMe) drives (PCIe Gen4) and 100 gigabit Ethernet (GbE) remote direct memory access (RDMA) networking. Dell Technologies tested workloads under these conditions:
- Healthy cluster running 64 virtual machines (VMs) per node
- Healthy cluster running 32 VMs per node
- Degraded cluster with one node failed
- Degraded cluster with two nodes failed
The configuration delivered outstanding results in all tested scenarios, even when the cluster was in a degraded condition. This means that end users will not notice reduced response times, even if it takes IT longer to return the cluster to its fully operational state. You’ll find all the testing details and results in this white paper.
Reasons to believe
When you modernize your virtualization clusters by deploying Dell EMC Integrated System for Azure Stack HCI, you can:
- Virtualize demanding applications that historically needed to remain on physical servers because of their performance requirements.
