4 . Ultra320 SCSI connectors (two 68-pin SCSIA1, SCSIB1)
This motherboard comes with the Adaptec® AIC-7902W SCSI U320 controller that support 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.
