RAID Configuration
One of the options available for your system is the
single channel DAC960PDU (Redundant Arr ay 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 controlle r to an
existing system, you must install, cable, and configure
the controller. The following subsections describe these
procedures.
