Disk Array Configuration of Additional Disk Unit
The N8141-36F additional disk unit is exclusively used for installation of hard disk drives. The
cabinet can contain up to 14 hard disk drives. The server equipped with disk array controller boards
(N8103-80/81) can be connected with up to four additional disk units. (See Chapter 10 or the
documentation coming with the additional disk unit for details of the additional disk units.)
IMPORTANT:
The additional disk unit does not contain hard disk drives. Purchase
the drives additionally.
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.
To connect the server with the N8141-36F additional disk unit, any of the following optional cables
are required:
K410-93(01) additional disk unit connecting SCSI cable
K410-93(03) additional disk unit connecting SCSI cable
K410-93(06) additional disk unit connecting SCSI cable
After the connection of the additional disk unit to the server, provide the disk array configuration for
the additional disk unit by using the Disk Array Configuration Utility. See the manual that comes
with the disk array controller for details of the procedure.
In the disk array configuration of the additional disk unit, the auto rebuild function which the disk
array controller board has can recover the data if any one of hard disk drives installed in the
additional disk unit is defected to destroy data. (Replace the defected hard disk drive with a new one
with the power being on (hot-swap)).
