9-42 Upgrading Your Server Several RAID (Redundant Arrays of Inexpensive [Independent] Disks) levels can be setfor the disk array configuration in the server in which disk array controller board isinstalled. Refer to the online document stored in "NEC EXPRESSBUILDER" CD-ROMcoming with the server or the documentation coming with the disk array controller fordetails 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 thanthe total capacity of the hard disk drives configuring the disk array while the diskreliability is improved. Set "PCI Slot n Option ROM (n: slot number)," a parameter of the slot in which a harddisk drive is installed, to "Enable" in "PCI Configuration" on the Advanced menu of theBIOS SETUP utility. Replacement of disk array controller boardRestore the disk array configuration information in the disk array controller boards. Usethe configuration utility for the restoration. Refer to the online document stored in "NECEXPRESSBUILDER" CD-ROM coming with the server or the documentation comingwith the disk array controller for details. If a disk array controller is replaced, create theconfiguration information by using the proper utility. When two or more disk array controller boards are installed in the server, install the diskarray controller board to which the system disk to be booted is connected in the PCI slothaving the highest priority. For example, if two disk array controller boards are installedin PCI slots #3 and #4, the system disk should be connected to the board installed in PCIslot #3.Slot No. Boot priority#5 3#4 4#3 1#2 5#1 2Using Internal Disks in Disk Array ConfigurationFor the installation of the RAID controller board, see "PCI Board" and the manual that comes withthe RAID controller board.Use the interface cable coming with the RAID controller board. Disconnect the cable from theserver and keep it for future use. After the installation, provide the setting such as RAID level forthe 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.
