Thread-topic: Xserve RAID: RAID 5 set using more than seven drives?
My question is, is RAID 50 safe (redundant)? My head gets confused when I try to think about raid systems greater than 5.

Piers,
You cannot span controllers with the xserve, so yes you are limited to 7
drives. One advantage of RAID 50 is performance.
Thanks,
