I'm getting a new server for our database, and I have a quick question
about RAID controllers with a battery backed cache.  I understand that the
cache will allow the cache to be written out if the power fails to the box,
which allows it to report a write as committed safely when it's not actually
        My question is, if the power goes off, and the drives stop, how does the
battery backed cache save things out to the dead drives?  Is there another
component that is implied that will provide power to the drives that I
should be looking into as well?
