Take Advantage of SAS Today
Because of its trusted reliability and stable feature set, the SCSI protocol has been accepted by the market for a remarkable twenty years. SAS leverages this continuing evolution of SCSI with new levels of calability, flexibility, and cost-effectiveness for connectivity, data transport, and data storage. The first SAS prototypes were announced in 2003 and were a major step to achieving mass market availability. Those prototypes allowed development of the first generation of technologies and products that bring the benefits of SAS into the enterprise. These products have been developed and tested, and enable a wide variety of integrated solutions.
Interoperability testing was a key component of SAS, because it increases the architecture’s flexibility by supporting both SAS and SATA disk drives and components. Interoperability allows one vendor’s SAS products to be compatible with another’s, and it also ensures products developed today will work with all existing and next-generation SATA products. Adaptec Unified Serial™ Architecture
This interoperability between SAS and SATA is the foundation of Adaptec Unified Serial Architecture, which integrates Unified Serial SAS-based controllers, the most advanced data protection available today, and a single management interface that works across all the connected storage. Unified Serial Architecture allows you to start taking advantage of the benefits of SAS today, even in SATA environments, and create
solutions that can be updated simply by swapping out the disk drives
