So why isn't auric running now? It's down on a "RAID failure" or
something like that, right?
If a cpu/mem board goes bad, is "just remove it" necessary for the
machine to keep working? What worries me is not the high-reliability
enterprise hardware doing it's job, but your "day or two" delay in
getting things back. The point of the N+1 rule, as I understand it,
is to give a different kind of redundancy, so that we don't have to
wait a day or two.
