Hitachi and LSI Logic to accelerate delivery of Serial Attached SCSI

Milpitas and San Jose, Calif. - March 25, 2003 - LSI Logic's Storage Standard Products division and Hitachi Global Storage Technologies today announced plans to coordinate their respective product development efforts to speed delivery of next-generation Serial Attached SCSI (SAS) technology. The companies plan to share design implementations, performance testing results and debug information, as well as participate in other joint activities.

LSI Logic plans to use the LSI Logic Fusion-MPT™ (Message Passing Technology) architecture to simplify and speed development. Hitachi expects to integrate 3Gb/s Serial Attached SCSI-based HDD products into its enterprise storage product line as customer demand increases for the new technology.

Hitachi and LSI Logic were founding members of the Serial Attached SCSI Working Group before submitting the emerging standard to the SCSI Trade Association and the T10 Committee. Both companies continue to be active members of these two standards organizations. LSI Logic products are expected to demonstrate later this year with availability in 2004.

"Serial Attached SCSI will allow Hitachi to extend its rock-solid server hard disk drive product line to create solutions that offer an even greater degree of reliability, scalability and performance for data center and other enterprise applications," said Fumio Kugiya, general manager, Server Business Unit, Hitachi Global Storage Technologies. "Hitachi has dedicated, worldwide resources and engineering leadership to deliver Serial Attached SCSI products to our customers both efficiently and cost-effectively."

"Successfully engaging with Hitachi for SAS product development is an important milestone as this new interface technology gains traction," said David Steele, LSI Logic Storage Standard Products director for product planning and management. "Having hard disk drive plug compatibility for both SAS and SATA will allow enterprise users to confidently continue to leverage SCSI technology, its scalability and robust reliability."

The SAS physical layer is compatible with Serial ATA (SATA), giving future users the choice of populating their systems with either SAS or SATA hard disk drives. This evolution of SCSI technology is seen as a natural next step in maintaining the industry's most robust and proven interface, and will allow enterprise customers to continue to leverage their existing investment in SCSI while gaining a 3Gb/s data transfer rate.

The SAS standard defines a device-level enterprise storage interface incorporating SCSI backward compatibility, serial point-to-point interconnections, dual porting, increased addressability and the ability to scale to small form factors. The SCSI Trade Association (http://www.scsita.org) has announced a SCSI product roadmap that will extend the industry's most successful interface technology to a new generation of serial devices.
