NVMe Tiering in vSphere 8.0 Update 3 is a Homelab game changer!

by // 90 Comments

As someone who is always on the lookout for interesting and clever ways to make the most out of your vSphere homelab investment, I was surprised there has not been more noise about the new NVMe Tiering capability in vSphere 8.0 Update 3!?

NVMe Tiering is currently in Tech Preview and it enables ESXi to use an NVMe device as a secondary tier of memory for your workloads, which IMHO makes it one of the killer features in vSphere 8.0 Update 3, especially with some interesting implications for Homelabs!

As the old saying goes, a picture is worth a thousand words ...


Picture on the left shows a system with 64GB of memory (DRAM) that is available before enabling NVMe Tiering and on the right, the amount of memory that is available after enabling the NVMe Tiering which is whopping 480GB! ?

Note: As of VCF 9.1, there is a more streamline method for enabling NVMe Tiering, please see this blog post for more details as the previously method no longer works.

Automated VMware Cloud Foundation (VCF) 5.2 Import Lab Deployment Script

by // 10 Comments

VMware Cloud Foundation (VCF) 5.2 had just GA'ed last week and it is a packed release with a ton of new capabilities! Creating a brand new VCF environment (greenfield) is generally much easier than converting an existing vSphere-based environment (brownfield) into a compliant VCF environment, which can be quite challenging and our users have been asking for a better solution.

With VCF 5.2, we now have the ability to import or convert an existing vSphere and vSAN environment into either a VCF Management Domain or Workload Domain using a new VCF Import Tool without needing to rebuild your existing environment!

As with anything I do, I typically want my infrastructure setup be fully automated, so that I can actually spend time exploring the actual capability and not waste time deploying or installing the required prerequisites. After spending a few minutes reading through the VCF Import Tool Scenarios and Considerations, I could adapt my Automated vSphere Lab Deployment scripts (here and here) to automatically deploy the required environment, so that I could quickly try out the new VCF Import Tool.

Auditing vGPU Profile Reconfigurations in vSphere

by // Leave a Comment

vCenter Server Events are extremely powerful and contains a ton of useful information, especially for auditing and compliance purposes. As of vSphere 8.0 Update 3, there are over 2.1K+ out of the box events with many more through 2nd and 3rd party integrations.

One of my favorite vCenter Server Event is the VmReconfiguredEvent as it provides complete visibility into every VM reconfiguration change as shared in this blog post back in 2015.

I recently saw an interesting inquiry about being able to audit and track vGPU profile reconfigurations for a VM and of course, vCenter Server Events to the rescue!
