Upgrading Your System 7-37

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 disks 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 disks in the disk array configuration or changing the RAID level initializes hard disks. If the hard disk to be configured in the array has your valuable data stored, make sure to make a backup copy of the data in another hard disk before installing the disk array controller board and configuring the array.

!The disk array configuration requires at least two hard disks.

!Use hard disks of the same capacity and performance (e.g., revolution) for each pack to configure them in the array.

!When connecting a disk array controller, start the BIOS SETUP utility, select [Boot] → [Hard Disk Drives], and set the 8th priority or earlier for the controller. If the 9th priority or later is set, the system is unable to start the disk array controller configuration menu.

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).

!A disk array configuration of RAID1, RAID5, or RAID0+1 increases disk reliability. However, the actually available capacity becomes smaller than the total hard disk capacity in the disk array configuration.
