Seagate Extends Serial Technology

Serial Attached SCSI and Serial ATA drives work together harmoniously in system in first public demonstration.

SCOTTS VALLEY, Calif. -- April 7, 2004 -- Seagate Technology today revealed its latest demonstration showing interoperability between multiple Serial Attached SCSI (SAS) and Serial ATA (SATA) disk drives all running within the same storage array. With the ability to freely mix SAS and SATA drives in a shared SAS-based system, IT managers will be able to use high-performance SAS drives for high-transaction and mission-critical data environments while simultaneously taking advantage of lower-cost-per-gigabyte SATA drives for the storage of non mission-critical reference data.

"By showing full interoperability between Serial Attached SCSI and Serial ATA drives in a single enclosure, Seagate is demonstrating the unprecedented flexibility IT managers will enjoy with deploying SAS in the enterprise," said Jeff Loebbaka, Seagate vice president of global marketing. "Consolidating drives using fewer, subsystems can save a substantial amount of both money and space, as well as reduce IT storage maintenance costs."

Serial Attached SCSI is the next step for the enterprise industry's storage I/O standard interface, according to Seagate. SAS technology extends SCSI interface solutions beyond Ultra320 to the next-generation Direct Attach Storage (DAS) server and workstation markets while retaining device-level backward compatibility. And because the SAS physical layer is compatible with SATA, users will have the choice of populating SAS systems with either SATA or SAS hard disk drives, or a combination of both. Boasting features that liberate SCSI from its parallel predecessor, Serial Attached SCSI delivers new levels of breakthrough speed and connectivity while retaining the functionality and reliability of SCSI.

With enterprise storage requirements escalating and becoming more complex, factors such as data center consolidation, reliability, security, scalability and accessibility are more critical than ever. Enterprise data centers must be online all the time, fulfill requests from numerous users simultaneously, allow for constant growth and expansion and be maintained while in operation. According to Seagate, Serial Attached SCSI meets all these demands while providing the highest performance at optimal capacity points.
