General vSAN Error

General vSAN Error

vSAN is a wonderful shared storage option in a vSphere cluster, but it requires an administrator with deep product knowledge and overall awareness to be able to manage it with an understanding of its quirks and gotchas.

Part 1 – PVRDMA and how to test it in home lab.

One of the members of the VMware User Community (VMTN) inspired me to build a configuration where two VMs use PVRDMA network adapters to communicate.
