Do the workloads need to share their state simultaneously? If not then you probably want SAN (exported block devices) instead of NAS (exported file systems).
Most of mine don’t, but I do have a couple that require it. For those I use SMB and squash all users to a “smb_users” users that I created in the NAS for this purpose
While I was writing the comment, I had in the back of my mind, “do I actually want iSCSI?” but it’s a whole can of worms I haven’t yet opened beyond reading the docs for csi-provisioner (which has direct support for provisioning per-workload zvols on my NAS)
