At the University Computation Center, they have 16 RA drives: 12
RA81s and 4 RA82s.  Other than being incredibly pleased with
the performance speedup, the ability to shadow-set large volumes,
and having another couple of gigs of storage, they have had no
problems.  Tonight, the drives are evenly spread across two HSC50s
(8 and 8).
