[rescue] Filesystem choice for fileserver?

i'm also planning to put a ZFS file server together (an E450 so i'll have
good disk bandwidth) and have read lots (but certainly not all) of the
Sun blogs and papers on ZFS.   there were several recommendations to use
JBOD because this ensures that the ZFS does its job and that when you use
other software or hardware RAID you don't get the full ZFS advantage for
bit-rot and other features that ensure data integrity.     so after a
failure, the other software or hardware RAID system makes sure that the
copies are consistent (in the case of full mirror, both copies will be
identical even if both have errors) and ZFS can't fix the error if i 
understand the point correctly.
