11. Two 68-pin Ultra320 SCSI Connectors (SCSI-A, SCSI-B)
This motherboard has two 68-Pin Ultra320 SCSI connectors; one for
each of the two channels. Each channel can support a maximum of 15
devices as specified by Ultra320 standards.
SCSI Connection Notes
This motherboard has two 68-Pin Ultra320 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, Ultra160, and Ultra320
devices. With Ultra320 devices, the SCSI bus platform performs at full
Ultra320 speeds (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.
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.
