Correct. You get a block device that you can put any filesystem you like on. > Does the client need ZFS support? Nope. As I understand it, when you do an iSCSI export of a ZFS pool, you're getting a block device with the advantages of the ZFS storage mechanism without any particular filesystem on it. I could be wrong, of course. I haven't played with that part of ZFS yet. On a tangent, I don't really see NFS and iSCSI really being in the same realm. NFS is more of a NAS/fileserving technology, useful for shared storage amongst many clients. iSCSI is a SAN technology, useful for dedicated storage for clients in a central location, analogous to fibre channel or ATAoE. -- Chip Marshall <c...@2bithacker.net> http://weblog.2bithacker.net/ KB1QYW PGP key ID 43C4819E v4sw5PUhw4/5ln5pr5FOPck4ma4u6FLOw5Xm5l5Ui2e4t4/5ARWb7HKOen6a2Xs5IMr2g6CM
