AEC-67160 Ultra160 SCSI Adapter
Chapter 1 Introduction
1.1 Introduction
ACARD technology corp. dedicate to make SCSI interface to be a standard
interface in PC and server field with stable function, high transfer rate and very low
cost. The ACARD SCSI adapter AEC-67160 is specificity designed to speed up
the high perform hard disk drive for server, Internet and RAID system or 3D image,
medical imaging, CAD/CAM designer. The AEC-67160 is a high performance PCI
Bus to a single channel Ultra160 SCSI, Low Voltage Differential (LVD) adapter.
The AEC-67160 is a high performance PCI-to-Ultra160 SCSI adapter. With full
features of the PCI 32-bit bus master transfer capability and PCI enhanced data
transfer commands (133MB/s). It offers real PCI Plug and Play, and Scatter/Gather
function to improve performance for multi-tasking OS.
The AEC-67160 supports peripheral devices which conform with SCSI-1, SCSI-2
and SCSI-3. For the bootable SCSI adapter AEC-67160, the biggest advantage the
adapter is a new generation of SCSI technology that expands SCSI performance
from 40 MB/sec to 160 MB/sec. In addition to providing much greater performance,
Ultra160 SCSI increases the maximum allowable cable length from 3 meters to 12
meters for improved connectivity and flexibility.
The key SCSI chip from ACARD is ATP880 32-bit RISC engine which highly
integrated with arbitration, disconnect, reconnect, parity generation and checking
on both data ports, synchronous data transfers with PCI PnP specification. Also,
the SCSI chip allows the ACARD SCSI adapter AEC-67160 to be backwards
compatible with previous generations of SCSI products, while allowing newer
Ultra160 SCSI devices to operate at the higher 160 MB/sec rate and increased
cable length.
