2-20 Chapter 2: Hardware information
6. Ultra160 SCSI connector (SCSI-B, 2U-SCSI)
This motherboard has two 68-Pin Ultra320 SCSI connectors, one
internal and one external. The SCSI connectors can support a
maximum of 15 devices as specified by Ultra320 standards.
SCSI Connection Notes
The onboard SCSI chipset incorporates an advanced multimode I/O cell
that supports both single-ended (SE), Ultra2, and Ultra320 devices. With
Ultra320 devices, the SCSI bus platform performs at full Ultra320 speed
(up to 320MB/s) and extended cabling 12m (or 25m in a point-to-point
configuration). When an SE device is attached, the bus defaults to an SE
speed and 1.5m cable length.
The internal and external SCSI connectors are on the same channel.
You may use only one connector at a time.
