3-20 Configuring Your System
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.
Ensure a jumper is installed on JP10 of the Mylex
AcceleRAID 250 Controller board. Refer to the Mylex
AcceleRAID Installation Guide for the location of jumper
JP10.
