Started unpacking the G5 Xserves today and their Xraids. There is documentation that implies the raid controllers fail over but it appears they do not. So, we have more controllers than necessary as the raids are only half loaded.... Also I'm not sure what Apple was thinking with the "key" on the front of these boxes. If you haven't seen it the "key" is a small hex bolt. I guess it is for securing against people who lack tool bags. Better setup a Swiss Army checkpoint at the door to the server room.
