Seagate heeft vandaag een demo gegeven van de Ultra320 SCSI technologie. Ultra320 verhoogt de doorvoer snelheid naar 320MB/s (duh) en is tegelijkertijd volledig backwards compatible met Ultra160 SCSI. Bestaande Ultra160 flatcables kunnen daardoor gewoon in gebruik blijven, wat erg prettig is gezien de nogal heftige prijs van deze kabeltjes. Tevens is het mogelijk om je nieuwe Ultra320 schijf op je oude Ultra160 controller te prikken.
Ultra320 komt nu dus eindelijk van de grond. Eerder kondigden Adaptec en LSI Logic als Ultra320 controllers aan. De Quantum Atlas 10K III is reeds Ultra320 compatible, evenals de voor Q1'01 aangekondigde IBM Ultrastar 73LZX:
Seagate Technology today announced that it has demonstrated Ultra320 SCSI disc drive technology that supports the industry proposals for the SPI-4 (Ultra320 SCSI) standard. The demonstration, conducted with a fully-integrated 320 Mbytes/sec SCSI initiator and target controller designed by Seagate, delivered data transfers at 320 Mbytes/sec and was accomplished with the same backplane and cabling used with the existing Ultra160 SCSI standard. Seagate tested numerous industry-leading Ultra160 systems to ensure interoperability between Ultra320 SCSI and Ultra160 SCSI. Ultra320 SCSI technology will enable businesses to move critical data with greater speed and reliability – a must for today’s booming Internet economy.
"This demonstration’s significance is not only in the fact that Seagate has furthered its technology leadership position, but that Seagate was able to show that Ultra320 SCSI can be implemented using existing infrastructures, including backplanes, cables, and terminators," said Tom Porter, executive vice president and chief technical officer, at Seagate Technology. "System integrators will appreciate this easy and cost-saving transition to Ultra320 SCSI, and we expect industry adoption to be rapid as a result."
Seagate Technology’s demonstration included the testing and implementation of the features found within the proposed ANSI standard. These include free-running clock, pre-compensation, training sequences, and cable deskewing. These features will help ensure that Ultra320 SCSI maintains interoperability and signal integrity in addition to increasing performance.
Seagate Technology has been a leader in the development of SPI-4 proposals, standards, and technical discussions for over a year, showing the first 320 Mbytes/sec technology on servers as early as last year’s COMDEX show. In September, Seagate offered an "Open Invitation to the Seagate Signaling Lab" to confirm existing cable and backplane properties and performance compliance with 320 Mbytes/sec transfers. Seagate has since shared the technical data with the SCSI cable and modeling working groups as well as the SPI-4 working group to enable common industry specifications.
