Diskeeper Corporation reveals that RAID devices must be kept defragmented to ensure maximum system performance and reliability. About this matter, Microsoft stated: "Just as with a single disk, files stored on RAID arrays can become fragmented, resulting in longer seek times during I/O operations."
As automatic as the sun rising, Diskeeper makes your systems run faster. With new InvisiTasking technology, Diskeeper eliminates potential problems IN REAL TIME without affecting system resources or intruding on system demands — a quantum leap in performance and reliability technology. Simply install the software — Diskeeper takes care of the rest. Although some vendors claim that RAID arrays do not get fragmented, they refer to the metadata used for file layout within the storage system, while the fragmentation at the disk file level, i.e. NTFS, is not taken into consideration.
Fragmentation affects the performance of a RAID environment because of the unnecessary generation of I/O issued by the file system. The RAID controller, unaware that the multiple I/Os all map to the same file, treats each I/O as a separate entity. A file object split into multiple I/Os is more likely to be interspersed with other disk I/O in a RAID stripe, than if the file I/O delivered to the controller was single. Defragmenting files at the file system level and consolidating data into a single I/O can better fill the entire chunk size with that I/O; now taking full advantage of the RAID.
Diskeeper Corporation claims: "...if an application has to issue multiple "unnecessary" I/O requests, as in the case of fragmentation, not only is the processor kept busier than needed, but once the I/O request has been issued, the RAID hardware/software must process it and determine to which physical member to direct the I/O request."
Fragmented hard drives drain critical system resources and compromise almost every aspect of daily system use, leading to longer load times, persistent lags and costly crashes. Diskeeper 2008 elevates server performance, debugging fragmentation-based problems as they occur, without ever compromising vital system resources - even during times of heaviest demand. Diskeeper 2008 with InvisiTasking represents the perfect tool to defragment RAID as it does it on the background as fragmentation occurs, thus letting them perform at their peak constantly.
InvisiTasking provides true transparent, background processing technology allowing for Diskeeper 2008 to defragment your servers in real-time, eliminating the need for cumbersome maintenance operations. Free up gridlocked resources and let your servers run at peak performance while you work. Diskeeper 2008 with InvisiTasking Server edition enhances the reliability and performance of your servers-automatically. Diskeeper's I-FAAST 2.0 (Intelligent File Access Acceleration Sequencing Technology) accelerates file access times to meet the heavy workloads of file-intensive applications. Utilising a specially formulated technology, I-FAAST closely monitors file usage and organises the most commonly accessed files for the fastest possible access, boosting file access and creation to speeds above and beyond the capabilities of your server when it was new – up to 80% faster.
