I'd create a mirror for rpool and the rest in another pool using raidz2.
Another note, have you bought disks already? You may want to take a look at 2.5" SAS disks from Seagate as they are enterprise grade with different firmware for better error recovery. I know the SAS backplane is picky sometimes. You may see disks disconnected with consumer level disks. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
