Haven't got a clue.  I don't keep up with the hardware anymore, so I have to
rely on the people who run it to explain these things.  One suggestion from a
disinterested third party was that, as shipped normally, all RAID disks run
off of a single disk controller.  If the controller fails _all_ of them are
toast.  It was further explained that you had to special-order a RAID
configuration that ran each set on its own controller.  But, this is just
hearsay...

I'm not familiar enough with it to know for sure, but I think it is _not_ to
back up.  I _do_ know that we have had to apply an awful lot of PTF's for it
on all of our systems...
