Agreed.  You could even potentially move the mirroring down to the
storage nodes (mirrored nbd/etc. devices) and HA the iSCSI target
service itself to reduce dom0's work, although that would depend on you
being comfortable with iSCSI moving around during a storage node
failure, which may be a risk factor.
