Using the Optional RAID Controller

The following paragraphs provide an overview of the optional Build-to-Order RAID controllers. Included is information on the factory installed controllers and RAID configurations.

Factory Installed Controller

One of the options available for your system is the dual channel Mylex AcceleRAID 250 Controller board, which gives your system the added security of fault tolerance.

If you order a system with the RAID controller, the system is pre-configured at the factory. Refer to the “RAID Configurations” table below to determine how the RAID controller was configured at the factory. If you want to reconfigure disk arrays and logical drives, you must run the AcceleRAID 250 BIOS Configuration Utility. If you want to change the RAID level, you must run the Mylex Disk Array Controller Utilities (DACCF) software. Refer to the AcceleRAID 250 documentation included with your system for information on running the AcceleRAID 250 BIOS Configuration Utility and the DACCF Utility.

Add-on Controller

If you are adding the RAID controller to an existing system, the AcceleRAID 250 BIOS Configuration Utility allows you to configure disk arrays and logical drives in your system. Since the utility resides in the AcceleRAID 250 BIOS on the RAID controller, its operation is independent of the operating system in your server. Refer to Chapter 4 in this User’s Guide for information on installing an add-in option board. Refer to Chapter 4 of the AcceleRAID 250 Installation Guide for information on running the AcceleRAID 250 BIOS Configuration Utility.

Note: Next Boot Status for the first Symbios SYM53C896 controller must be turned OFF if you install the optional Mylex AcceleRAID™ 250 Controller board in your system. Refer to “Symbios Configuration Utility” found earlier in this chapter.
