It depends on your load, system setup and wishes of administration ;-)
Having more than one partition helps in distributing the load in the
system slightly better, also the load in network, if you do have more
than one NIC and one harddrive for the iSCSI storage.
Having more than one partition raises administration overhead (on which
partition is my volume now, wehre is the RO copy,..), so it is not for fr=

If you have more than one HD to save data on, I would suggest more than
one partition on suifficient load. If you have only 2 volumes and 3
users, it really does not care much^^
