SCSI Celebrates 25th Anniversary of Benefits to the Storage Industry.

SAN FRANCISCO -- The SCSI Trade Association (STA), a member-run industry association established to support and promote SCSI technology, announced today that the Small Computer System Interface (SCSI) is celebrating 25 years of excellence in providing the leading storage I/O technology to enterprise systems worldwide. At its zenith, SCSI held more than 80% of the market in storage I/O. The successor to SCSI, Serial Attached SCSI (SAS), is rapidly replacing legacy SCSI as the leadership storage technology.

At its beginning in 1981, the future SCSI was a cooperative venture between NCR (NCR's effort was spearheaded by John Lohmeyer, now with LSI Logic, and the head of the T10 Technical Committee) and Shugart Associates. The two companies joined forces to propose SASI (an early I/O technology that Shugart was developing), as a draft document for a prospective ANSI (American National Standards Institute) standard at the ANSI X3T9.3 Committee meeting in October 1981. With acceptance by ANSI and the addition of other storage companies to develop the new technology, SASI was renamed SCSI and became the legendary storage I/O.

Harry Mason, Director, Industry Marketing, LSI Logic and President of STA, stated, "SCSI has been a fundamental component of multi-user storage architecture since its inception. While its legacy has had a profound impact on the server market and the creation of other logical SCSI compatible standards, its most exciting era lies ahead. The market transformation to Serial Attached SCSI is now in full swing and virtually guarantees that SCSI will remain at the forefront of enterprise storage for the foreseeable future."

John Lohmeyer, Principal Engineer, LSI Logic, and Chair of the T10 Technical Committee, commented, "Between 1982 and 1984, numerous additional enhancements and functionality were added to SCSI and in 1986, the first SCSI standard was published by ANSI. Looking back, I marvel at how quickly we were able to complete the first SCSI specification. Our effort provided the standard SCSI storage I/O that stimulated the storage industry to grow very rapidly."

Carrying on the SCSI legacy, SAS technology development is based on the roadmap going out to 2012 with 12 Gb/s performance. T10 technical committee meetings are held six times per year to advance the technology. Currently, many SAS-based products, including complete storage systems, are available on the market.
