Don't do that!
Agreed. A further issue to consider is mean time to recover/restore. This has quite a lot to do with actual uptime. For example, if you decide to create two huge 22TB LUNs and mirror across them, if ZFS needs to resilver one of the LUNs it will take a *long* time. A good design will try to keep any storage area which needs to be resilvered small enough that it may be restored quickly and risk of secondary failure is minimized.
