An A7173A Ultra320 SCSI adapter, used in an HP entry-level or mid-range PA-RISC server, is an excellent industry-leading solution for critical SCSI storage applications. This paper provides I/O performance and CPU utilization information for the HP A7173A PCI-X Dual-Channel Ultra320 SCSI Host Bus Adapter (A7173A U320 Adapter), and highlights its significant performance increase over the HP A6829A PCI Dual Channel Ultra160 SCSI Host Bus Adapter (A6829A U160 Adapter) on HP's PA-RISC based servers.
