Ultra 160 SCSI ports
The server has an integrated dual-channel Ultra 160 small computer system
interface (SCSI) controller. This controller supports two independent Ultra 160 SCSI
channels: one internal and one external. Each of these channels supports up to 15
SCSI devices. In addition, this controller uses:
v Double-transition clocking to achieve high transfer rates
v Domain name validation to negotiate compatible data transfer speeds with each
v Cyclic-redundancy checking (CRC), instead of the usual parity checking, to
v An active terminator on the system board for SCSI bus termination
