I have to place a lot of NSS Pools/Volumes on an iSCSI Target (NW65SP7) and I have a question about the best way to size the partition.

What is the better ?

1) Create a large iSCSI partition, and create all the necessary NSS partitions for my Pools on these unique iSCSI partition.
2) Create a lot of iSCSI partition of the size of my Pools ans have an organization like "an iSCSI partition for each NSS partition"

Help and /or comments appreciated.
