Disk and package manufacturer are serial to 6Gb/s join SCSI (SAS) feel special excitement, but memory user still needs proper time to observe them after all some more excited what.

"The " of below one phase of the natural evolution that 6G SAS is SAS, the company product sale of rare nimble carries out chief inspector Henry Fabian to say, "The rate of 6G SAS rose double " .

Next generation memory interface that regard Ultra320 as collateral SCSI, SAS is for at first interior and external connect form continuously (DAS) environment and of the design. But the supportive SAS as a result of it and SATA (serial ATA) the ability of driver, in exterior memory, it obtained fast adoption as driver interface, produced brand-new memory layer from this- - the SAS of high rate and tall usability, and high capacity and the SATA that store greatly.

"Although run paralell SCSI environment of DAS of be confined to, but SAS brought new function, can be in be similar to SAN (memory local area network) SAS is used in deploy, you can say a kind to this is but the patulous, DAS" that can share, the David So of manager of sale of product of ministry of memory component career of LSI Corp says, "This kind of framework had gotten adoption " in the system of a few razor blade nowadays.

LSI and other SAS firms had rolled out a few SAS to arrive the exterior RAID of SAS (independent disk is redundant array) subsystem, and SAS switching equipment. Current 3Gb/sSAS also created 2.5 inches of small-sized measure (SFF) the market of company level driver. In 6Gb/sSAS drive, face towards the trend of 2.5 inches of driver predicts to still will continue. Besides clear appearance advantage, SAS still has feebleminded bad news and low calorific advantage.

"The function of 6Gb/sSAS promotes further, make it has appeal " more as the lead plane interface of exterior memory, so says, "These promotion included the divisional framework of a standardization, and the limitative " that goes going up besides setting of a few SAS.

Novel point

6Gb/sSAS is SCSI (interface of all of small-sized computer science department) guild (STA) the sale term that removes to be based on the occupation standard place of SAS-2 standard. Next generation SAS agreements defined a series of functions, those who include the data rate of 6Gb/s and ego setting is patulous implement. This kind of function makes patulous implement can oneself discover develop attacks the change of layout, is not to rely on lead plane controller, promoted equipment so but expansibility, and improved systematic performance- - because expand implement carry out discovery OK and collaterally function.

In the standard other upgrade the new divisional arrangement that includes to ensure each other operates a gender between the manufacturer, wire cable length from the 6 methods that control to 10 meters to 8 meters of promotion, and the signal that use a program to carry out high-end network and needs and data integrality function.
