Overview: The market transition from parallel to serial interface technologies is irrefutable. SAS is the newest serial interconnect and successor to iSCSI. SAS has leveraged SCSI technology and improved upon it to offer an improved host interface, as well as drive technology, to meet these increasingly rigorous performance and scalability requirements. With a solid roadmap and industry acceptance behind it, SAS technology is proving to be the next evolution of SCSI. The most recent of these is with the introduction of the Sun StorageTek 2500 series of arrays based on SAS technology.
