That, or your guests uses disk I/O lightly :) You didn't mention what your domU uses are. If it's for I/O intensive database, remote storage (NFS or whatever) is probably a no-no. You might even want to stick with local storage due to its performance. However, if you use it for light-wight web servers, or DNS/DHCP servers, then NFS is probably fine. PS: since you're looking for a NAS anyway, I suggest you try looking at Solaris 10 or opensolaris, which has zfs volumes (exportable via iscsi). This should make your job a lot easier as it supports snapshot and clones from storage server, compression, and checksum for data integrity.
