Folks, 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 committed. 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? Thanks, Peter Darley
