3-Channel RAID Controller Installation

This chapter contains the information needed to install either the EISA or PCI 3-Channel RAID

Controller Board in a host computer.

The 3-channel RAID controller boards combine the functionality of a SCSI-

based RAID controller with the host computer’s internal EISA or PCI bus.

The EISA board has four connectors: two channel-0 connectors, a channel-1

connector, and a channel-2 connector. One of the Channel-0 connectors is on the

EISA board’s edge and the second is on an external connector. These connectors

are electrically identical and mutually exclusive, that is, only one of the connec-

tors can be used.

The PCI board has five connectors: two channel-0 connectors, two channel-1

connectors, and one channel-2 connector. Channel-0 and channel-1 each have a

connector on the PCI board’s edge and an external second connector. The con-

nectors for each channel are electrically identical and mutually exclusive - only

one of the connectors for each channel can be used. The edge connectors on the

PCI board are of the 68-pin high-density type. The bulkhead connectors are 0.8-

mm 68-pin connectors.
