* The numbers in brackets (x or x+y) specify the quantity of drive bays connected to each of the controllers.
** A combination of any two of the RAID 530-8i, RAID 730-8i, and RAID 930-8i controllers is supported
Configuration note: Models without any drive bays are based on the 16x 2.5" chassis (feature code AV0R),
and they support adding drive bays by using the 2.5" 8-drive backplane kit (7XH7A06254).
