26 Setting Up and Using Your Computer
If a drive failure occurs, subsequent read and write operations are directed to the surviving drive. A
replacement drive can then be rebuilt using the data from the surviving drive. Also, because data is
duplicated on both drives, two 120-GB RAID level 1 drives collectively have a maximum of 120-GB
on which to store data.
Configuring Your Computer for RAID
You may want to configure your computer for RAID at some point, if you did not select a RAID
configuration when you purchased your computer. You must have at least two hard drives
installed in your computer to set up a RAID configuration. For instructions on how to install a
hard drive, see "Hard Drive" on page 79.
You can use one of two methods to configure RAID hard drive volumes. One method uses the
Intel RAID Option ROM utility and is performed before you install the operating system onto
the hard drive. The second method uses the Intel Matrix Storage Manager, or Intel Matrix
Storage Console, and this method is performed after you have installed the operating system
and the Intel Matrix Storage Console. Both methods require that you set your computer to
RAID-enabled mode before starting any of the RAID configuration procedures in this
document.
