RAID Configuration

One of the options available for your system is the single channel DAC960PDU (Redundant Array of Inexpensive Devices (RAID) 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-cabled at the factory (see Figure A-3).

If you are adding the DAC960PDU controller to an existing system, you must install, cable, and configure the controller. The following subsections describe these procedures.
