Chapter 1 5
Features
The A6828A adapter and its driver conform to the ANSI T10 SCSI
Parallel Interace-3 (SPI-3) standard.
The A6828A adapter has the following features:
• PCI interface
— Full 64-bit (66 MHz) Direct Memory Access (DMA) bus master.
— Zero wait-state bus master data bursts.
— PCI Universal 3.3 V/5 V bus support.
— Compliance with PCI Local Bus Specification, Revision 2.2.
• SCSI interface
— One SCSI channel.
— 16-bit (Wide) Single Ended (SE)/Low Voltage Differential (LVD).
— Enabling/disabling of on-board termination, with hardware
override (using a jumper).
— 68-pin Very High Density Cable Interconnect (VHDCI)
connector on the external channel.
— 68-pin High Density connector on the internal channel (not
supported on HP-UX systems).
— Maximum data transfer rate of 160 MBytes/s per channel, with a
maximum cable length of 12 meters (with multiple SCSI devices)
and a maximum 15 SCSI devices on the single channel (not
including the A6828A adapter).
— Fast, Ultra, Ultra2, and Ultra160 data transfer capability.
— SCSI termination power (TERMPWR) source with auto-resetting
circuit breaker.
— Flash EEPROM configured with HP part number (allows easy
identification through the ioscan command).
• HBA characteristics
— PCI4X adapter (66MHz, 64-bit data transfers).
