But as the year progressed, Serial Attached SCSI (SAS), SCSI's serial replacement technology, evolved to become last year's principal storage trend as it joined forces with SATA to begin supplanting the aging parallel SCSI
The mature parallel SCSI
interface is ideal for Small to Medium Businesses (SMBs) deploying direct attached storage for business critical applications.
For those who prefer parallel SCSI
, the SuperServer 6035B-8R+ features the SC836S2-R800 chassis to support 16 hot-swap, dual-channel U320 SCSI drives and 16 memory slots for up to 64GB FBD DDR2.
SAS is a next-generation serial interface designed to extend the capabilities of today's parallel SCSI
drives and provide users with improved performance, system design flexibility and product reliability.
For example, there are new devices available such as the Ultra SPI-3 (SCSI-3 Parallel Interface) and SPI-4, and Ultra160 or Ultra320 parallel SCSI
Compared with preceding parallel SCSI
channels, basic FC-AL provides: Higher data throughput with up to 5x more bandwidth over SCSI; Greater scalability, addressing up to 7x more disk drives per channel; Greater distances between servers and storage pools with cabling lengths increased more than 20x (multi-mode) or 400x (single-mode); and Expanded connectivity options based on fibre channel hubs and switches.
The 3ware 9690SA-4I, with its attractive price point, makes 3ware SAS available to a greater audience as it helps to more cost effectively replace the aging parallel SCSI
Overcoming many of the limitations of traditional parallel SCSI
implementations, SAS solutions that offer connectivity choices and support both SAS and Serial ATA (SATA) drive technology enable enterprises to easily create tiered storage environments.
Offering enhanced performance, reliability and scalability, SAS overcomes many of the current limitations associated with the traditional parallel SCSI
5- to 10-fold increase in effective data bandwidth over the traditional parallel SCSI
The server market has successfully transitioned from parallel SCSI
, which dominated the market for over 20 years, to 3Gb/s SAS," stated Harry Mason, Director, Industry Marketing, LSI, and President of STA.
SAS maintains proven parallel SCSI
command set support and management capabilities while enabling a seamless transition from SCSI systems, offering increased performance, scalability, reliability and flexibility.
