SCSI Channel Configurations

SCSI Channel Configurations

The backplane SCSI channels 1 and 2 can support eight SCSI devices. You can configure the backplane as single-channel (combine) or dual-channel (split) controller.

In single-channel configuration, channel 1 supports the SCSI devices plugged into slots 1 through 8.

In a dual-channel configuration, channel 1 supports the devices in slots 1 through 4, and channel 2 supports the devices in slots 5 through 8.
