For details, see the online documentation in the ExpressBuilder DVD provided with the
server. (The utility varies depending on the RAID Controller.) For details on the data
transfer rate, RAID, and RAID System configuration, refer as well to the manual
provided with the RAID Controller.
Caution
When an Optional RAID Controller is installed, do not let the
system enter hibernation or standby mode.
Disk Expansion Unit
A disk expansion unit is an exclusive device in which up to 14 hard disk drives can be
installed. (The number of hard disk drives depends on the model.)
A server containing a RAID Controller can be connected to one or two of these
devices. For more information, see the manuals provided with the RAID Controller and
disk expansion unit.
Caution
A disk expansion unit is provided without hard disk drives. The
hard disk drives must be purchased separately.
An optional cable may be required to connect with a disk expansion unit. Refer to the
manual provided with the disk expansion unit for details.
Connect the disk expansion unit, and use the RAID System configuration utility of the
onboard controller to set the disk expansion unit in a RAID System (RAID0, RAID1,
or RAID5). (The utility varies depending on the RAID Controller.) For more
information on the settings and the methods to use, refer to the online document in the
ExpressBuilder DVD provided with the server or to the manual provided with the
board.
When a disk expansion unit is set in a RAID System, you can use the "Auto Rebuild"
feature of the RAID Controller to restore data if one of the hard disk drives installed in
the disk expansion unit fails. (Hot-swap the failing hard disk drive).
Caution
When an Optional RAID Controller is installed, do not let the
system enter hibernation or standby mode.
