VSAN Homelab HCL

As this is a storage platform where you might end up migrating your homelab production data, keep in mind that by using components not certified by VMware, you can end up in VSAN nightmare. But YMMV.


The official VSAN HCL file is available here. This is a JSON formatted file which is the source of knowledge behind the VSAN Health Check Plugin. This is a good start to finding VSAN compatible hardware, which can be also found on the VMware's official HCL.
