RAID BIOS

The RAID (Redundant Array of Inexpensive Devices) option available for your system is N8103-
80F/81F/86F RAID controller boards which give your system the added security of fault tolerance.
If you want to change the RAID level or add additional hard disk drives to the array, use the RAID
configuration utility. The RAID configuration utility is included with a RAID controller.
If you are adding the RAID controller to an existing system, the RAID configuration utility allows
you to configure your disk array before reinstalling your network operating system. The RAID
controllers support various versions of RAID technology (referred to as RAID levels). To use any
RAID level, you must configure the RAID controller using the RAID configuration utility prior to
installing your Network Operating System. For an explanation of this utility, refer to the
documentation that comes with the RAID controller. It describes RAID technology and provides
tips on making your array perform well in your specific application. It also covers array hardware
preparation, configuration, and initialization. After completing the steps in the manual, you can
install your Network Operating System.
If you want to remotely configure the array (from a PC client); increase array capacity online; or
monitor statistics on disk and controller activity, you must install the array manager provided with
your RAID subsystem. Increasing array capacity is covered in the documentation shipped with the
option.
