I say on the contrary. iSCSI and ZFS is a match in heaven;-) Regarding wiki for ZFS over iSCSI: There simply is not more to it - follow the advice and you are up and running. As Steffen mentions: A two or three node setup using a Solaris (Omnios in my case) based ZFS shared storage and the performance is unbeaten. Steffen uses 10 Gb ethernet while I use Infiniband DDR with this setup and a proper RAID 10 ZFS should give you: Random read I/0: ca. 4000 iops Random write I/O: ca. 1200-1500 iops Add to this: Life migration, life snapshots, linked clones. -- Hilsen/Regards Michael Rasmussen Get my public GnuPG keys: michael <at> rasmussen <dot> cc http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xD3C9A00E mir <at> datanom <dot> net http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE501F51C mir <at> miras <dot> org http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE3E80917 -------------------------------------------------------------- /usr/games/fortune -es says: The time spent on any item of the agenda [of a finance committee] will be in inverse proportion to the sum involved. -- C.
