Each RKXS 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 WMS100 can be configured with 1 RKXS and up to 6 RKAJAT units for a total of 105 GB
disk drives at a maximum of 38.5 Tbytes RAID5(14D+1P) (using the 393.4 G 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.)
Note 2: When FC interface board is not added, one port configures one Mini-HUB, and extends to two host connectors. When
FC interface board is added, control unit implements two ports and two host connectors. One port configures FC interface
independent of another port, and implements one host connector.
Note 3: When the FC interface board is added, the interface type supports 4 Gbps Fibre Channel Optical (Non-OFC).
Note 4: When the FC interface board is added, a maximum data transfer rate is 400
M bytes/s (Fibre Channel) depending on the host I/O condition.
Note 5: For additional information about the global rack-mount model, refer to the Acer | HDS Global 19-Inch Rack Reference
Guide.
