ZFS includes support for RAID0 (stripe), RAID1 (mirroring), RAID5 and RAID6 (raidz1/raidz2), and (soon in OpenSolaris) RAID7 (raidz3). Why would you want to build a pool out of devices that are already RAID'd together? Just use the bare disks, or slices on disks, or partitions even. -- Freddie Cash fjwcash@gmail.com
