NOTE: To change your computer’s orientation from either tower to desktop or desktop to tower, you must use an optional kit available from Dell. See "Product Information" on page 291 for more details on ordering from Dell. With the purchase of an optional kit from Dell, you can change the configuration of your Dell Precision computer between desktop and tower modes.

Page 49: About Raid Configurations
While there are many RAID configurations available in the computer industry for different types of uses, Dell offers RAID level 0, RAID level 1, or RAID level 5 on your Dell Precision computer.
Page 50: Raid Level 0
Intel RAID configuration program. If you have three drives and two are in a RAID level 1 configuration, the third drive can be used as a spare drive for the RAID configuration (see "Creating a Spare Hard Drive" on page 60). A RAID level 5 array must be made up of three drives.
Page 51: Raid Level 1
RAID Level 1 RAID level 1 uses a data-redundancy storage technique known as "mirroring." When data is written to the primary drive, the data is then duplicated—or mirrored—on the other drive. A RAID level 1 configuration sacrifices high-data access rates for its data redundancy advantages. segment 1 segment 2 segment 3...
Page 52 Since parity data is fairly small when compared to the size of the actual stored data, the equivalent of one hard drive can serve as a parity drive for any number of data-storing hard drives. However, not all of the parity data is put on the same drive.
Page 53: Configuring Your Computer For Raid
Configuring Your Computer for RAID At some point you may want to configure your computer for RAID 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.
