Begins the transition to SAS shestigigabitny

In mid-November, Fujitsu officially announced the development of a 2.5- inch hard. SAS- disks. Enterprise -class. They will be used for the first time recently received the status of the second version of industry standard interface Serial Attached SCSI (SAS), which provides data transfer rates of 6 Gb / s. The new series will include MBD2 RC model with a speed of 10 thousand. rev / min and up to 300 GB, which will be released in the I quarter of next year, and model MBE2 RC at 15 thousand. rev / min and a maximum capacity of 147 GB, planned for the II quarter. According to Fujitsu, through the use of the second version of SAS data transfer rate of these drives will increase by up to 60 % compared with 2.5- inch hard drives based on the SAS trehgigabitnogo.

While SAS drives were used only in servers and storage systems, entry-level, but in October, the company introduced the HDS midrange array AMS2000, constructed on the basis trehgigabitnogo SAS ( though they are equipped with 3.5- inch disks ). Some market analysts believe that soon the SAS, which has virtually replaced Parallel SCSI, may become the standard for arrays of middle and junior class, and Fibre Channel drives will remain only in the storage sector, high-end.

Go to shestigigabitny SAS will further increase the advantage of this technology over Fibre Channel. Although this year appeared on the market for storage products based on vosmigabitnogo Fibre Channel, none of the manufacturers of hard drives does not plan to use this interface, so for today 's fastest drives are based on the Fibre Channel 4 Gb / s. And the appearance of the following year swap SAS 6 Gb / s company Fujitsu ( which probably will soon join, and the largest hard drive manufacturer Seagate, have already demonstrated prototypes of such devices ) will mean that it is this technology can provide the best performance I / O. According to IDC, the wide introduction of the second version of SAS will begin in the second half of 2009. and by the time you have started mass production of components of servers and storage systems that support this interface.
