Setting Up and Using Your Computer 27
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.
NOTE:
In a RAID level 1 configuration, the size of the configuration is equal to the size of the smallest drive in the
configuration.
Configuring Your Hard Drives for RAID
Your computer can be configured for RAID, even if you did not select a RAID configuration when the
computer was purchased. For an explanation of RAID levels and their requirements, see "About Your
RAID Configuration" on page 25. For information on how to install a hard drive, see "Installing a Hard
Drive" on page 101.
You can use one of two methods to configure RAID hard drive volumes. The first method uses the
NVIDIA MediaShield ROM utility and is performed before you install the operating system onto the
hard drive. The second method uses NVIDIA MediaShield and is performed after you have installed the
operating system and NVIDIA RAID drivers.
Both methods require that you set your computer to RAID-enabled mode before you begin.
