SAS (Serial Attached SCSI) enables a common backplane to handle deployment of both 15K SAS drives for online storage and 7200 RPM SATA drives for near-line storage, all in a single enclosure. Since SAS and SATA drives share a common backplane, a single SAS-based subsystem can handle a broad range of enterprise storage duties, from high-availability online storage to data migration, disk-to-disk backup and storage of regulatory compliance or other reference data.
Using tiered storage, enterprise customers can maintain true system flexibility and investment protection. Critical enterprise applications that require the highest-performance and reliability can use SAS drives, while less critical applications and data can be stored on SATA drives.
"A tiered storage approach is the best choice for users interested in ensuring they can meet their I/O transaction and bulk storage needs while maintaining the lowest total cost of ownership (TCO) at a system level," said Jeff Loebbaka, Seagate vice president of global marketing. "Seagate continues to work with the world's largest system makers to help them develop these systems. We understand that their customers are always interested in solutions that provide greater benefits."
Based on a SAS backplane, the system demonstrated at IDF uses components from LSI Logic and Adaptec. At IDF, Seagate is also demonstrating the benefits of high-density storage that highlights the tremendous I/O and space-saving benefits of Savvio, the world's first 2.5-inch enterprise class disc drive.
About Serial Attached SCSI
Serial Attached SCSI is the logical evolution SCSI. 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 that has made SCSI the only enterprise storage I/O standard with more than two decades of use.
With enterprise storage requirements escalating and becoming more complex, factors such as larger capacity, greater density, 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 must be maintained while in operation. Serial Attached SCSI meets all these demands while providing the highest performance. Seagate expects to deliver Serial Attached SCSI products this fall.
