Page 39: About Raid Configurations
Although there are several RAID configurations available in the computer industry for different types of uses, Dell offers RAID level 0, RAID level 1, or, with an optional PCI Express RAID controller, RAID level 5 or RAID level 10 on your Dell Precision computer.
Page 40: Raid Level 0
NOTE: RAID levels do not represent a hierarchy. A RAID level 5 configuration is not inherently better or worse than a RAID level 0 configuration. The RAID controller on your computer can only create a RAID level 0 configuration using two to four physical drives. A RAID level 5 or 10 array (only available with the optional PCI Express RAID controller) must be made up of three or four drives.
Page 41: Raid Level 1
NOTICE: Because RAID level 0 provides no data redundancy, if one drive fails, then the data on the other drive is also inaccessible. Therefore, ensure that you perform regular backups when you use a RAID level 0 configuration. RAID Level 1 RAID level 1 uses a data-redundancy storage technique known as "mirroring."...
Page 42 RAID level 5 uses a data-staging storage technique known as "parity checking." When a block of data is written to the RAID configuration, it is striped across all of the drives in the RAID array except for one drive, to which is written parity data.
Page 43: Raid Level 10
RAID Level 10 NOTE: RAID levels 5 and 10 are only available via an optional PCI Express RAID controller card. RAID level 10 uses a combination of striping and mirroring methods. It requires four drives. The drives are broken up into mirroring pairs and then the data that is written to the RAID configuration is striped across all four drives.

Exit Screen It is important to exit the RAID Configuration Utility properly, because some changes take effect only when you exit. From the Adapter List, press <Esc> to exit. In addition, a similar exit screen appears when you exit most other screens, and it can be used to save settings.
Page 46: Creating A Raid Level 1 Configuration
NOTICE: All data will be lost upon creation of the RAID volume. Dell recommends backing up your data before performing these steps. When creating an IS (striped) RAID volume: • All drives must be either Dell compliant SAS or SATA hard drives.
Page 47: Creating A Second Raid Volume
• Drives must have 512 byte blocks and must not have removable media. • There can only be 2 hard drives per RAID volume. 5 Press <C> and then select Save changes when the RAID volume has been fully configured. 6 Exit this menu to save the changes.
Page 48: Synchronizing A Raid Volume (Virtual Disk)
Synchronizing a RAID Volume (Virtual Disk) When a RAID volume is synchronized, the firmware synchronizes the data on the secondary hard drive(s) with the data on the primary hard drive of the RAID level 1 volume. Follow these steps to start synchronization for a RAID level 1 volume: 1 Select Synchronize Virtual Disk.
Page 49: Replacing And Rebuilding A Degraded Raid Volume
Replacing and Rebuilding a Degraded RAID Volume In the event of a hard drive failure in a RAID level 1 volume, you will need to replace the hard drive and resynchronize the RAID volume. 1 Replace the failed drive with a new drive of the same type and capacity (or larger capacity).
