I’m not using LUNs, I’m using NFS, which unfortunately is not very well covered in that document.

See the above TR for best practices with VMWare ESX.  Lun alignment is crucial to performance with an environment that has many VMDK's.

Subject: Is there a limit to the number of VM's per NFS export?

For the folks using NFS to hold their VMDK files, have you run into a limit to how many VM’s a  single share can support? Either a hard limit or just a point where performance degrades? I’m trying to figure out how many volumes I’ll need to create to hold ~300 VMs on my 3070 cluster.
