[PVE-User] Shared SAN <> ZFS concept

Not in the ZFS world but in the Proxmox world.

You can use the SAN storage as shared LVM storage on top of FC or iSCSI.
https://pve.proxmox.com/wiki/Storage#_storage_types <https://pve.proxmox.com/wiki/Storage#_storage_types>
I’ve been using such a setup for years (even with a mix of FC and iSCSI).

For a Proxmox HA cluster you’ll need a third node or quorum device though.

You won’t get that with the SAN but have a look at Proxmox Backup Server.
The live-restore feature lets you boot from a(ny) backup almost instantly.
