There are some Disk Arrays that only support Mirroring or Raid5. Raid5 stores the parity on a different disk, where StripeZ would store parity in the standard record size block. ie as long as you can read the block, it has a chance of recovering it. The Array H/W is responsible for ensure the Data is not lost, the StripeZ has the ability to recover from chksum faults. It would use more disk than standard Stripe, but would give much better performance than RaidZ on top of H/W Raid.
Pro's/Con's of doing such a thing? Cheers -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
