4.6.1 AMS200 Rack-Mount Model
Each RKS unit contains the physical disk drives, including the disk array groups and the
dynamic spare disk drives. Each rack frame has dual power plugs, which should be attached
to two different power sources or power panels.
The AMS200 can be configured with 1 RK and up to 6 RKAJ units for a total of 105 GB disk
drives at a maximum of 28.1 Tbytes RAID5(14D+1P) (using the 287.6 G disk drive). The
AMS200 can also be configured with 1 RKS and up to 6 RKAJAT units for a total of 105 disk
drives at a maximum of 37.0 Tbytes RAID5(14D+1P) (using the 393.9 G disk drive).
