Adaptec Rolls Out Serial Attached SCSI with 3 Gigabit/Second Speed

11/11/2003 - Adaptec, Inc. (NASDAQ:ADPT), a global leader in storage solutions, became the first company to achieve full first-generation Serial Attached SCSI speeds of 3 gigabits/second in tests of an ASIC that reached peak throughput of 5 gigabits/second. The signal transmission keeps Adaptec on track to deliver first-to-market 3-gigabit-second Serial Attached SCSI solutions that provide new levels of workstation and server performance for database, streaming video and audio, mainline storage, video editing and other bandwidth-intensive enterprise applications.

The Adaptec Serial Attached SCSI ASIC also is architected to run at second-generation Serial Attached SCSI speeds of 6 gigabits/second. Early delivery of the dual-architecture ASIC will enable system builders to speed time-to-market of first-generation Serial Attached SCSI solutions and reduce costs of second-generation solutions.

The ASIC will incorporate Adaptec's HostRAID data protection technology and is part of Adaptec's suite of interoperable end-to-end solutions that allows businesses to seamlessly scale data protection, performance and capacity to their growing storage needs. Businesses deploying systems powered by Adaptec's Serial Attached SCSI ASICs will be able to easily migrate to Adaptec's add-in cards and direct- and network-attached external storage solutions.

Adaptec Drives Transition to Serial Attached SCSI
In today's achievement, a prototype Adaptec ASIC generated the Serial Attached SCSI data and Adaptec link technology converted the data commands into electrical signals transmitted over a serial cable at 3 gigabits/second - the two key capabilities required to build Serial Attached SCSI chips.

"Adaptec is powering the transition to new levels of computing throughput, scalability and reliability with the development of Serial Attached SCSI solutions," said Ahmet Houssein, vice president and general manager of Adaptec's Storage Solutions Group. "Our early validation of the capabilities needed to build Serial Attached SCSI systems will enable system builders to speed time-to-market of Serial Attached SCSI solutions and drive early adoption."

Adaptec's transmission of the first 3-gigabit/second Serial Attached SCSI data comes five months after Adaptec staged the first demonstration of the interface supporting both enterprise-class Serial Attached SCSI drives and Serial ATA drives for cost-sensitive applications. Adaptec also demonstrated the industry's first prototype Serial Attached SCSI ASIC architected to run at both 3- and 6-gigabits/second.

"Market interest in Serial Attached SCSI continues to build as product development efforts keep the industry on track to introduce Serial Attached SCSI systems by mid 2004," said John Monroe, a research vice president at Gartner Dataquest. "The interface's support for storage of both high-demand transactional data and archived reference information, combined with its ability to deliver greater system throughput and scalability, could make it a significant part of the enterprise market starting in 2005."

Serial Attached SCSI controllers and disk drives will deliver first-generation data transfer rates of 3 gigabits/second with a roadmap to 12 gigabits/second (1,200 megabytes/second), providing the highest levels of performance for bandwidth-intensive enterprise applications.
