It is more cost-effective than Fibre Channel. Today, SCSI is the technology of choice for the vast majority of server and high-performance PC environments. This is due to the important features of upgradability, scalability, manageability, inter-generational device compatibility, reliability and performance. As SCSI continues to increase in speed and add new features, it promises to remain a viable technology for storage and for desktop connectivity in the long-term. The market is demanding longer distance connectivity and greater peripheral connection capability as well as dynamic configuration features.
Low cost remains an important factor.
In addition, new expanders, new extenders and LUN bridges are on the horizon. Another widely demanded feature hot swap. SCSI specification development is currently underway to provide these features within a competitive price range. Important future SCSI developments will be the increased performance defined by Ultra320 and Ultra640, with additional generations to follow. Planned features for Ultra320 include double edge clocking, packetized protocol and domain validation with signal margining.
