Adaptec, HP and Seagate Technology Team to Debut Compatibility of Serial Attached SCSI and Serial ATA at CeBit America

Industry Leaders Collaborate to Drive Serial Attached SCSI and Serial ATA Interoperability, Deliver Unprecedented Storage Flexibility for System Builders and End Users

Adaptec, Inc. (NASDAQ:ADPT), HP (NYSE:HPQ) and Seagate Technology (NYSE:STX) will team to debut the Serial Attached SCSI interface working with both Serial Attached SCSI and Serial ATA disk drives June 18-20 at CeBIT America in New York City.

Serial Attached SCSI and Serial ATA compatibility will give organizations a new level of flexibility in configuring disk storage for cost and performance in direct-attached and networked storage deployments. The joint demonstration in the SAN Exchange Pavilion, booth 2419, at the Jacob K. Javits Center will highlight the Serial Attached SCSI interface's support for both Serial Attached SCSI drives and Serial ATA drives. Serial Attached SCSI also enables the design of smaller form factor disk drives for high-density computing environments.

"Serial Attached SCSI and small form factor enterprise-class drives will provide scalable speed, decreased power consumption and increased integration flexibility for diverse data needs in a variety of storage system architectures," said John Monroe, a research vice president at Gartner Dataquest.

Serial Attached SCSI - Supporting Transactional and Reference Data

By supporting both Serial Attached SCSI and Serial ATA disk drives, the Serial Attached SCSI interconnect will let organizations easily deploy and manage disk storage in servers, external storage appliances and networked storage solutions based on the performance and capacity requirements of each data type, such as:

  • Reference data, consisting of infrequently accessed or archived information including electronic documents, presentations and graphics used in word processing, email, graphics, CAD/CAM, medical diagnostic and other applications; and
  • Transactional data, typically high-demand information frequently and concurrently accessed by multiple users. This includes data from e-commerce, credit card and bank transactions, customer relationship management (CRM), supply chain management (SRM), multimedia and other bandwidth-intensive enterprise applications.

New Flexibility For Deploying and Managing Storage

Serial Attached SCSI and Serial ATA disk drive compatibility will offer a number of key benefits to system builders, integrators and end users:

  • End users will enjoy a new level of price/performance flexibility. Serial ATA drives will provide cost-effective capacity for reference data, while Serial Attached SCSI drives will deliver the highest performance, reliability and software management compatibility for transactional data. The ability to upgrade from Serial ATA to Serial Attached SCSI drives without having to buy a new system will simplify the purchasing decision, future-proof system server investments and reduce total cost of ownership.
  • System builders will be able to leverage the universal Serial Attached SCSI interconnect to deploy common backplanes, connectors and cabling. Upgrading from Serial ATA to Serial Attached SCSI will be as simple as replacing the disk drives. Other cost-saving benefits of compatibility include simpler new-product validation and inventory management.
  • VARs and system integrators will be able to standardize on a single interface, allowing them to easily configure custom systems by simply installing the appropriate disk drive type.

Serial Attached SCSI Technical Capabilities

Serial Attached SCSI solutions also will feature:

  • Data transfer rates of 3 gigabits/second with a roadmap to 12 gigabits/second (1,200 megabytes/second) to deliver the highest levels of 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.
  • Dual porting for improved redundancy to enable the design of high-availability systems.
  • Expander hardware to enable highly flexible and scalable storage configurations of more than 16,000 mixed Serial Attached SCSI and Serial ATA disk drives.
  • Thinner cables and smaller connectors than traditional parallel technologies, enabling better chassis airflow and cooling, simpler cable routing and design of smaller form factor hard drives for high-density computing.

Industry Leaders Team to Showcase Serial Attached SCSI at CeBIT

"Adaptec, HP and Seagate are working to give customers greater disk drive flexibility in the enterprise," said Jeff Jenkins, acting vice president, Server Storage and Infrastructure, HP Industry Standard Servers. "Serial Attached SCSI offers 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 cost-effective bulk storage capacity."

"Serial Attached SCSI will combine logical SCSI compatibility with new levels of performance, scalability and data availability to meet organizations' growing storage needs and help future-proof their storage investments," said Gary Gentry, Seagate Technology vice president, Business Development and Planning. "Adaptec, HP and Seagate Technology are pleased to be highlighting Serial Attached SCSI interconnect as the ideal choice for both Serial ATA and Serial Attached SCSI disk storage deployments in the enterprise."

"Adaptec is pleased to be extending its longstanding product development and engineering relationships with HP and Seagate to develop Serial Attached SCSI solutions and drive early adoption," said Ahmet Houssein, vice president and general manager of Adaptec's Storage Solutions Group. "Our joint demonstration of Serial Attached SCSI/Serial ATA compatibility at CeBIT is a significant milestone in these efforts. The ability to plug both Serial Attached SCSI and Serial ATA disk drives into the same system will give IT managers, system integrators and original equipment manufacturers unprecedented disk storage flexibility."
