Using Internal Disks In Disk Array Configuration - NEC Express5800 120Li User Manual

9-42 Upgrading Your Server
Several RAID (Redundant Arrays of Inexpensive [Independent] Disks) levels can be set
for the disk array configuration in the server in which disk array controller board is
installed. Refer to the online document stored in "NEC EXPRESSBUILDER" CD-ROM
coming with the server or the documentation coming with the disk array controller for
details of the available RAIDs, data transfer rate, and array configuration.
The available capacity of the hard disk drives in the disk array configuration is lower than
the total capacity of the hard disk drives configuring the disk array while the disk
reliability is improved.
Set "PCI Slot n Option ROM (n: slot number)," a parameter of the slot in which a hard
disk drive is installed, to "Enable" in "PCI Configuration" on the Advanced menu of the
BIOS SETUP utility.
Replacement of disk array controller board
Restore the disk array configuration information in the disk array controller boards. Use
the configuration utility for the restoration. Refer to the online document stored in "NEC
EXPRESSBUILDER" CD-ROM coming with the server or the documentation coming
with the disk array controller for details. If a disk array controller is replaced, create the
configuration information by using the proper utility.
When two or more disk array controller boards are installed in the server, install the disk
array controller board to which the system disk to be booted is connected in the PCI slot
having the highest priority. For example, if two disk array controller boards are installed
in PCI slots #3 and #4, the system disk should be connected to the board installed in PCI
slot #3.

Using Internal Disks in Disk Array Configuration

For the installation of the RAID controller board, see "PCI Board" and the manual that comes with
the RAID controller board.
Use the interface cable coming with the RAID controller board. Disconnect the cable from the
server and keep it for future use. After the installation, provide the setting such as RAID level for
the RAID controller board by using the disk array BIOS utility of the board.
Refer to the manual that comes with the RAID controller board for details.
