VMware over NFS maybe used in SMB (small medium businesses) enterprises use iscsi or SANs

when the NFS server crashes bad things happen and if you are building a redundant multi master NFS it’s a lot simpler to use iscsi and FC SAN

At my workplace we run VMware over NFS served by Netapp clusters. It's very stable, performs well, is easy to manage and has functioning HA. We used to have a SAN but Netapp worked well enough that it was decommissioned.

My favourite moment operating one cluster was when I intentionally caused a kernel panic and core dump on a live production system to gather debug info for an issue we were having. It had zero observable impact. :) Netapp is not cheap, but they seem to know what they're doing.
