so some kind of raid/pool setup with ssd/memory caches
or something like that?

iSCSI will result in 'block' transfers (similar goes for
AOE) so that requires a filesystem on the client with all
the filesystem overhead, but it might provide better
performance for 'certain' workloads

than having the entire guest on NFS?

also, the 'zfs hybrid box' is a different machine than
the one running the guests?

please clarify the setup, otherwise it's mostly hand
waving and probably useless for your setup
