New VMware Community HCL

by // 10 Comments

If you are not using or can not use the official VMware Hardware Compatibility List (HCL) to identify hardware systems and components that are officially supported with a given version of vSphere ESXi, then the experience in finding hardware can be quite daunting for both new and even existing users. Typically, users might start off by searching online or posting in the VMTN Community Forums and although I have attempted to help in this space with my VMware Community Homelab project, which attempts to crowd source working configuration and build-of-materials (BOM) that can assist, it certainly is a big challenge.

Even if you are successful in the initial assessment, there are no guarantees that your hardware configuration will be compatible with future vSphere ESXi releases and the investigative process will likely have to start all over again or simply with trial and error, which can also be frustrating for new users. I have always wanted and I know many of you in the community have also expressed similiar options in having a VMware Community HCL that can be used and maintain by the community.

Today, I am excited to share that we now have a platform that can enable an "unofficial" VMware Community HCL!

Updating the VSAN HCL & Release Catalog DB using VSAN API

by // 2 Comments

Both the VSAN Hardware Compatibility List (HCL) and the VSAN Release Catalog database which provides VSAN build recommendations should be updated periodically to ensure that you have the latest VSAN recommendations from VMware. In addition to using the vSphere UI to perform these update, customers can also automate either of these tasks using the VSAN Management API which can be consumed using any of the supported VSAN Management SDKs including PowerCLI.


I recently had a question about which VSAN API to use to update VSAN Release Catalog.

How to check when the VSAN Hardware Compatibility List (HCL) is updated?

by // 1 Comment

While catching up on emails from being out on paternity leave, I came across a VSAN HCL feature request that I had filed in early December of last year. I was pleasantly surprise to see that it had been marked resolved. The VSAN Hardware Compatibility List is continuously being updated to include new hardware platforms and components that have been certified by our hardware vendors.

This of course is great news for our customers, but one challenge that I have heard on several occasion is how to keep up with the changes, especially the addition of new components? The VSAN HCL allows you to subscribe and get notification on individual components which is useful to get the latest recommendation. However, in the case of new components being add or even removed, there is no easy solution and most folks resort to manually checking the VSAN HCL by hand.

VSAN itself does include an HCL healthcheck, which you can have it directly pull the latest VSAN HCL JSON from VMware's website, although this may not always be possible for customers without direct or proxy access to the internet. This means for customers who may have dark sites, they must periodically download the latest VSAN HCL JSON and distribute that throughout their vCenter Server, where as a more ideal solution is to only push the update when a new JSON has been provided by VMware.

My feature request was quite simple, it asks for a method in which customers can easily subscribe and get notified of when the VSAN HCL database has been updated. This has been delivered as a tiny RSS feed service.
