Optional SCSI Duplex Configuration

Compaq ProLiant 5500 servers that are optionally configured in the duplex
mode split the hard drive backplane board (duplex board) into two separate
independent SCSI channels. Each channel supports either 4 X 1" or 3 X 1.6"
drives.

Duplex SCSI Channels

In the Compaq ProLiant 5500 server, the duplex board has two SCSI input
channels, designated SCSI Input 0 and SCSI Input 1. These connectors are
shown in Figure 7-11.
