ESXi-Arm V2 Easter Egg

by // 5 Comments

A new version of the ESXi-Arm Fling (V2) was recently released and the major update to the ESXi-Arm V2 Fling is that it is now based on the latest ESXi 8.x codebase, which is currently 8.0 Update 3b. In my blog post, I had hinted there was a small easter egg 🐣 the Engineering team had included in the ESXi-Arm Fling update, which I did not know about until they had mentioned it!

Since no one has officially found the easter egg, I figured it might be time to break the silence and share as I think it can actually benefit some users based on their usage of ESXi, especially from a testing and/or learning perspective such as playing with the vSphere API as just one example.

How to upgrade VMware Cloud Foundation (VCF) with PVSCSI controller incompatibility?

by // Leave a Comment

If you are running VMware Cloud Foundation (VCF) in a lab using Nested ESXi and you attempt an upgrade workflow, you may find the following upgrade pre-check fail with the following message: VSAN SCSI controller is not VMware certified


You might think you are out of luck, but it is actually pretty straight forward to bypass the checks and still allow the upgrade to proceed, something I recently went through myself when upgrading my VCF 5.1.1 environment to the latest 5.2 release.

Note: To use vSAN ESA in VCF, you should configure your Nested ESXi VM to use an NVMe Controller instead of PVSCSI Controller, so its possible that by changing the controller type, you may not run into this error simliar to findings here. You can also override the vSAN HCL JSON with your own custom HCL JSON which includes the PVSCSI controller by following the blog post here and that would also allow you to proceed, but steps below are the easiest as you do not have to do anything special.

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

by // 88 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! 🤯
