I know the PERC H200 can be flashed with IT firmware, making it in effect a "dumb" HBA perfect for ZFS usage. Perhaps the H800 has the same? (If not, can you get the machine configured with a H200?) If that's not an option, I think Option 2 will work. My first ZFS server ran on a PERC 5/i, and I was forced to make 8 single-drive RAID 0s in the PERC Option ROM, but Solaris did not seem to mind that. --khd _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
