Running close to full you will eventually run into fragmentation
you can grow the size of a pool while it's hot, get some more LUNs
just do a zpool add. Highly recommend it until there's a patch to add
defrag for ZFS pools. You're the first person I've read using iSCSI
that add a bunch of latency? And 7200 RPM SATA to boot.
