Well, a 6140 with RAID 10 is not an option because we don't want to lose 50% disk capacity. So, we're left with RAID 5. Yes, we could layer ZFS on top of this. But what do you do if you want RAID 6? Easiest way to get it is ZFS RAIDZ2 on top of JBOD. The only reason I'd consider RAID is if the HW RAID performance was enough of a win over ZFS SW RAID. -- albert chin ([EMAIL PROTECTED]) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
