One of the key considerations in developing a new technology is interoperability. As witnessed by the early issues with Fibre Channel solutions, market acceptance of a new technology, no matter what performance gains or cost reductions it provides, will be slowed by interoperability doubts.
As a result, interoperability has been a focal point throughout the development of the Serial Attached SCSI (SAS) technology standard and products. SCSI Trade Association and its members are committed to providing fully interoperable products, and in 2004, three plugfests at the University of New Hampshire InterOperability Laboratory tested for both SAS and Serial ATA (SATA) compatibility and multi-vendor interoperability. Components tested for interoperability included disk drives, controllers, test equipment, cables, connectors and systems. The fourth SAS plugfest, held April 25-29, 2005, continued this commitment.
This electrical level interoperability testing provides peace of mind that products can be connected to other products from multiple vendors and integrated into existing environments. However, creating SAS solutions, particularly early in the adoption process, requires more than hardware interoperability.
