On a SAN machine, I personally use TGT[1] as a target. It's a totally 
separate machine to other Proxmox VE instances; it is just a SAN, there 
are no guests running on it etc.


I make each virtual machine use a different target.

This is because it lets you add/remove/modify targets without affecting 
other (running) targets.
With on giant target with many luns, the above is just not possible.

Also, this approach lets you find out (on the initiator) which target 
uses which block device - just look into symlinks created by udev in 
/dev/disk/by-path/.
