What happens if one of the drives goes or if the software component (0) goes? -----Original Message----- From: Bill Lloyd [mailto:email@hidden] Sent: Fri 10/29/2004 3:33 PM To: Ken Carlile Cc: Mac OSX Server Subject: Re: Xserve RAID: RAID 5 set using more than seven drives? It is safe for data, because if a RAID controller goes bad, you won't lose data. Swap in a new RAID controller, it can read the RAID set info off the drives, and you're back up and running in no time. If you have a spare controller on hand (i.e. you purchased a spares kit), this swap takes 30-60 seconds. However, it does have "uptime" implications. If a controller goes, the entire volume (that is, both halves) goes offline for the duration. This effectively doubles your chances of losing availability. It's two "single points of failure" and some people won't tolerate ANY, so if that's your goal, it's not a recommended approach.
