1.3 SCSI Concepts
Before configuring the SurfRAID TRITON Mini, you must first understand
some basic SCSI concepts so that the SurfRAID TRITON Mini and SCSI
devices will function properly.
1.3.1 Multiple SCSI Format Support
The SurfRAID TRITON Mini support the SCSI interface standards listed be-
low. Note that the data bit and cable length restrictions must be followed.

1.3.2 Host SCSI ID Selection
A SCSI ID is an identifier assigned to SCSI devices which enables them to
communicate with a computer when they are attached to a host adapter via
the SCSI bus. Each SCSI device, and the host adapter itself, must have a
SCSI ID number (Ultra 320 Wide SCSI = 0 to 15). The ID defines each SCSI
device on the SCSI bus. If there is more than one SCSI adapter in the Sur-
fRAID TRITON Mini, each adapter forms a separate SCSI bus. SCSI IDs can
be reused as long as the ID is assigned to a device on a separate SCSI bus.
Refer to the documentation that came with your peripheral device to deter-
mine the ID and how to change it. The SurfRAID TRITON Mini must be
assigned a unique SCSI ID ranging from 0 to 15. The default value is ID 0.
