SCSI Celebrates 25th Anniversary of Benefits to the Storage Industry.SAN FRANCISCO -- The SCSI Trade Association The SCSI Trade Association, or SCSITA, is an industry trade group which exists to promote the use SCSI technology. It was formed in 1996 [1]. As of 2006, major members include Adaptec, HP, Intel, LSI Logic, Seagate, and IBM [1]. (STA), a member-run industry association established to support and promote SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. technology, announced today that the Small Computer System Interface (SCSI) is celebrating 25 years of excellence in providing the leading storage I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output 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 See SAS. (SAS (1) (SAS Institute Inc., Cary, NC, www.sas.com) A software company that specializes in data warehousing and decision support software based on the SAS System. Founded in 1976, SAS is one of the world's largest privately held software companies. See SAS System. ), 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 Corporation, Dayton, OH, www.ncr.com) A technology company specializing in financial terminal transactions, retail systems and data warehousing. Until the late 1990s, NCR was heavily invested in the hardware side of the industry, known worldwide as a major manufacturer of computers (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 (Shugart Associates Systems Interface) A peripheral interface developed by Shugart in 1981 that evolved into the ANSI SCSI standard in 1986. It was renamed SCSI because ANSI does not allow corporate names in its standards. See SCSI. (an early I/O technology that Shugart was developing), as a draft document for a prospective ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. (American National Standards Institute See ANSI. (body, standard) American National Standards Institute - (ANSI) The private, non-profit organisation (501(c)3) responsible for approving US standards in many areas, including computers and communications. ANSI is a member of ISO. ) 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. About STA The SCSI Trade Association was established in 1995 to provide a focal point for members to communicate the benefits of SCSI to the industry. STA promotes the understanding and use of SCSI technology and influences the evolution of SCSI standards to meet future industry needs. The Association has a nine-member Board of Directors that oversees the Marketing Communications and Technology Committees and all STA activities.
