Configuring RAID
RAID Configuration Utility
The RAID (Redundant Array of Inexpensive Devices) option available for your system
is either a RAID controller board, a RAID chipset on the motherboard, or both
(depending on your configuration) which gives 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 the 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, check this user’s guide for basic informations,
and refer to the documentation that comes with the RAID controller (the
manufacturer’s documentation is generally included on the ExpressBuilder disc). 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 Operating System.
