Sas Disc Views
The SAS Disk Cleanup Handler Utility is new. The SAS Disk Cleanup Handler will search for and clean any temporary files or directories that were generated by SAS. The SAS Disc Cleanup Handler Utility cleans directories such as SAS Work and SAS_util directories as well. SAS Disk Cleanup Handler is a COM hook into the Microsoft Disk Cleanup Handler (cleanmgr.exe).
Some IT experts expect there to be more data created and stored in the next 5 years than at any time in the history of the world. Requirements like these for large volume data storage, compounded by fast query requirements are stretching the processing capability of parallel SCSI technology. The only answer is to change the protocol for accessing data from disc drives-enter Serial Attached SCSI, or SAS. By transitioning from parallel to serial, the disc drives are able to transmit data from point to point, instead of sharing bandwidth across a single common data bus. Therefore, SAS virtually eliminates the bottleneck that parallel SCSI processing could never overcome.
John Monroe at Gartner indicates, SAS is now being qualified by the major OEMs. By 2008 to 2010 (estimates vary) all SCSI drives will be SAS drives . Some IT OEM's have an even more aggressive rollout schedule. Referring to SAS disc drives, Craig Butler at IBM states, The drives will become standard on servers by 2006 . Although serial processing technology is new to enterprise servers, it is not new to the IT industry. Serial connections are commonly used on USB connections, on Fire Wire, and for almost all new printer connections. Enterprise servers are actually late in adopting the serial technology that can reduce bottlenecks and increase data processing speeds.
Naturally, rebuild times are also much quicker with small disk drives. The small drives allow data to be spread over more spindles, which allow for fast re-build. Flexibility is also improved for customers who will be able to mix and match different drives in the same back plane. A unique feature of the SAS technology allows both the high end Serial Attached SCSI and the entry level Serial ATA drives to be mixed and matched in the same serial drive cage. Customers might choose to have one JBOD with 5 SAS SFF drives on one RAID set running mission critical applications, while 5 SFF SATA drives are in the same JBOD storing reference data. Customers now have unprecedented flexibility and opportunity to lower their total cost of IT ownership by selecting the right hard disc drive for the proper application.
