Introduction
The HP Single Channel Ultra320 SCSI Host Bus Adapter (HBA) G2 contains one
independent low-voltage differential SCSI (LVDS) channel that interfaces directly between
the server PCI or PCI-X local bus and up to 15 SCSI devices. The adapter supports industry-
standard interfaces and protocols. The Single Channel Ultra320 SCSI HBA G2 can be used
with all SCSI devices, including Ultra320 SCSI, Ultra160 SCSI, Ultra2 SCSI, and Ultra
SCSI. For optimum performance and throughput, the SCSI HBA card must be installed in a
64-bit, 133-MHz, PCI-X slot with Ultra320 devices.
Features
Standard SCSI features of the Single Channel Ultra320 SCSI HBA G2 include:
•
Support of Ultra320 and legacy modes and devices, including single-ended (SE) or
multimode low-voltage differential (LVD) devices (high-voltage differential [HVD]
devices are not supported)
•
One bootable SCSI channel
•
SCSI data transfers up to 320 MB/s
•
Narrow or Wide SCSI data path
•
Single independent channel that allows LVD and SE devices to operate separately at peak
performance
•
Automatic detection and communication with Ultra320 SCSI, Ultra160 SCSI, Ultra2
SCSI, and Ultra SCSI
•
One 68-pin wide SCSI internal connector that supports Ultra320 SCSI, Ultra160 SCSI,
Ultra2 SCSI, and Ultra SCSI
•
One Very High-Density Cable Interconnect (VHDCI) external connectors that support
