10. Two 68-pin Ultra160/320 SCSI Connectors (SCSI1, SCSI2)
This motherboard has two 68-Pin Ultra160/320 SCSI connectors; one
for each of the two channels. Each channel can support a maximum of
15 devices as specified by Ultra160/320 standards.
SCSI Connection Notes
This motherboard has two 68-Pin Ultra160/320 SCSI connectors; one for
each of the two channels.
The onboard SCSI chipset incorporates an advanced multimode I/O cell
that supports both single-ended (SE), Ultra2, and Ultra160/320 devices.
With Ultra160/320 devices, the SCSI bus platform performs at full
Ultra160/320 speeds (up to 160MB/s or 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.
Connect SCSI devices as shown. Each channel should have only one
type of SCSI standard (e.g. Ultra320, Ultra160, Ultra2, Ultra-Wide).
Mixing SCSI devices on the same channel decreases performance of
the slower device.
