DISK ARRAY CONTROLLER BOARD
The disk array controller board is an optional PCI board provided to improve data reliability.
Installing the disk array controller board allows you to use hard disk drives in the device bays of the
server and those in the optional expansion disk cabinet in the disk array configuration.
IMPORTANT:
The disk array controller board is extremely sensitive to static
electricity. Make sure to touch the metal frame of the Server to
discharge static electricity from your body before handling the disk
array controller board. Do not touch the disk array controller board
terminals or on-board parts by a bare hand or place the disk array
controller board directly on the desk. For static notes, see the section
"Anti-static Measures" described earlier.
Making hard disk drives in the disk array configuration or changing
the RAID level initializes hard disk drives. If the hard disk drive to
be configured in the array has your valuable data stored, make sure
to make a backup copy of the data before installing the disk array
controller board and configuring the array.
The disk array configuration requires at least two hard disk drives.
Use hard disk drives of the same capacity and performance (e.g.,
revolution) for each pack to configure them in the array.
NOTES:
Before installing a disk array controller board, start the SETUP
utility, select [Advanced]
→
[PCI Configuration], and confirm that
[Enabled] is set for the parameter [PCI Slot xx ROM] (xx: PCI slot
number).
Your mother board includes the RAID controller. The onboard
RAID controller supports the RAID0 and RAID1.
A disk array configuration of RAID1 or RAID5 increases disk
reliability. However, the actually available capacity becomes smaller
than the total hard disk drive capacity in the disk array
configuration.
