6. Ultra320 SCSI connectors (one 68-pin SCSIA1)
[P5MT-S model only]
This motherboard comes with the Adaptec AIC-7901 PCI-X SCSI U320
controller that supports one 68-Pin Ultra320 SCSI connector. The SCSI
channel can support a maximum of 15 SCSI devices as specified by Ultra320
standards.
SCSI connection notes
This motherboard has a 68-Pin Ultra320 SCSI connector.
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 specified. A SCSI channel should have only one type
of SCSI standard (e.g. Ultra320, Ultra160, Ultra2, Ultra-Wide). Mixing SCSI
devices on a single channel decreases performance of the slower device.
