Adaptec First to Transmit Serial Attached SCSI Protocol Packet

3/20/2003 - Adaptec, Inc. (Nasdaq: ADPT), the global leader in data storage access solutions, extended its SCSI technology and market leadership by becoming the first host bus adapter provider to send a Serial Attached SCSI protocol packet over a serial wire. The protocol transmission puts Adaptec on track to bring the first Serial Attached SCSI chip and controller card to market to meet next-generation computing demands for performance, scalability, flexibility, data protection and component size.

"Adaptec's achievement of the first Serial Attached SCSI protocol packet transmission over serial cabling is a key milestone in the development of chips and controllers that will deliver the next generation of system performance, reliability, scalability and data protection," said Ahmet Houssein, vice president and general manager of Adaptec's Storage Solutions Group. "Our Serial Attached SCSI chips and controller cards will give our customers better price performance and the flexibility to choose either SATA or Serial Attached SCSI drive solutions to meet their specific application needs. This will maximize return on investment as they work to manage and store growing amounts of information."

Adaptec sent the Serial Attached SCSI protocol packets from a serial RAID card prototype to four hard disk drives over a serial line and back without error.

Serial Attached SCSI - One Interface, Many Solutions
Adaptec's Serial Attached SCSI interface will offer new levels of customer choice by supporting both enterprise-class Serial Attached SCSI drives and Serial ATA drives for cost-sensitive applications. OEMs and IT managers will have the flexibility to configure drive arrays with either drive technology, or both, enabling the use of both high-performance and low-cost storage in the same server or storage appliance. Customers will be able to more easily deploy storage assets to meet the needs of specific applications, such as file serving, application services, disk-based backup and archiving.

"Design flexibility and the potential to seamlessly scale cost and performance metrics on the same bus would certainly be attractive attributes of Serial Attached SCSI-based systems," said John Monroe, a Vice President at Gartner Dataquest. "Market acceptance of Serial Attached SCSI by major OEM accounts seems promising. If components can be delivered on time and qualifications go smoothly, Serial Attached SCSI will begin to gain significant ground in 2004 and could become a substantial part of the enterprise market in 2005 and 2006."

Adaptec's Serial Attached SCSI solutions will feature a roadmap to 12-gigabits (1,200 megabytes/second) to optimize system performance for bandwidth-intensive applications such as mainline storage, video editing, and streaming video and audio in direct-attached, networked-attached and networked storage environments.

The solutions will include a full line of interoperable Serial Attached SCSI initiators, expanders and bridges - all the chip-level components needed to build Serial Attached SCSI systems. Adaptec's Serial Attached SCSI solutions also will support dual-ported disk drives, currently available only with Fibre Channel products, to deliver a level of fault tolerance previously not available at a midmarket price point. All the solutions will include Adaptec RAID so IT managers can protect all their workstation and server data.

"Industry leaders like Adaptec and HP are helping to deliver on the promise of greater customer choice in the enterprise with Serial Attached SCSI," said Brad Anderson, vice president, Server Storage and Infrastructure, HP Industry Standard Servers. "Serial Attached SCSI has the promise to offer customers exceptional choice on their price-performance requirements, allowing server and storage customers to choose the technology that fits their specific needs - Serial Attached SCSI for performance and reliability or Serial ATA for the lowest acquisition cost."
