Connecting with Additional Disk Unit /
Sample Connection in Maximum Configuration
To connect an additional disk unit with the server, the disk array controller (N8103-81/90/126) is
required.
IMPORTANT:
To connect with additional disk unit, use the server of
rack-mount type, or use the additional disk unit of tower type (pedestal
type). In both cases, you need an optional conversion kit.
The additional disk unit N8141-36F can be connected to the server equipped with the disk array
controller board. (A single N8141-36F contains 14 hard disk drives. Up to two units can be
connected.)
The server can be connected with up to 121 hard disk drives (9 hard disk drives internally installed
and 6 units of additional disk unit (each unit can contain 14 hard disk drives).
Four SCSI disk array controller boards are required to connect the server with additional disk unit.
The server can be equipped up to four SCSI disk array controller board. Accordingly, in this
configuration, the eight hard disk drives installed in hard disk drive bay and HDD cage are
controlled by onboard RAID controller and used as RAID0 or RAID1 disk array, or a single SCSI
device.
