4.6.2 Floor Model
Each floor model contains physical disk drives, including the disk array groups and the
dynamic spare disk drives. Additionally, each floor model has dual power plugs, which should
be attached to two different power sources or power panels.
Floor (RKS+H1J) Model can be configured with 15 disk drives at a maximum of 4.0 Tbytes
RAID5 (using the 287.6 Gbyte disk drive).
Floor (RKS+RKAJ+H2J) Model can be configured with 30 disk drives at a maximum of 8.0
Tbytes RAID5 (using the 287.6 Gbyte disk drive).

Note 1: This value of storage capacity is calculated as 1 Gbyte = 1,000,000,000 bytes. (This
definition is different from 1 Kbyte = 1,024 bytes.)
