I don't have any direct experience with iSCSI, but I think it's likely
it would be "correct" since it's a lower level protocol than NFS, i.e.
from the computer's standpoint it thinks it's talking to a local SCSI
drive (maybe)?

But performance wise I'm not sure if it'd be better or worse ... if it
must cross the same network connection as your NFS connection it seems
likely it'd also have performance issues?
