I wish RHEL would support XFS/ZFS, but for now, I'm stuck with ext3.

there is ext4 (or ext4dev) - it's an ext3 modified to support 1024 PB size
(1048576 TB). You could check if it's feasible. Personally I'd always
stick with ext2/ext3/ext4 since it is most widely used and thus has
the best recovery tools.

Something else to keep in mind...XFS fs repair tools require large amounts of memory. If you were to create one or a few really huge fs's on this array, you might end up with fs's which can't be repaired because you don't have or even can't get a machine with enough RAM for the job...not to mention the amount of time it would take.
