This has known to be negative impact on physical servers with direct-attached storage. With the use of resources in a virtual infrastructure, the problem is magnified even more. The additional unnecessary disk-I/O traffic affects not only the responsible operating system, but also on all other operating systems, which share the limited resources. This fragmentation is manifested as storage networks, which no longer provide the same performance as at the beginning, in applications with higher latency, users must always longer waiting until file upload, and challenges in terms of maximizing the density of virtual machine on a host platform. Removing fragmentation has been proven to improve the I/O performance (www.diskeeper.com/ business/v-locity /? apid = PPS0006651). David Chernicoff explains the problem in his presentation to maximize the performance of your Windows SAN infrastructure (downloads.diskeeper.com/pdf/Performance-Windows-SAN.pdf) “simple words: since the SAN file system at the hardware level is managed by the SAN and each client is connecting to the SAN, treated the SAN for local storage, managed the SAN file system regardless of the manner, such as the server operating system writes data.” This means that the source of fragmentation must be tackled the data must be written to the SAN in a manner which minimizes the scattered storage when writing the data and allows more disk I/o San to be passed. Eliminating the fragmentation reduced the number of required disk o of of i /, to meet your business needs. If possible the same work with less effort, means lower costs and better performance. Diskeeper Corporation, leading provider of performance software, has developed a new technology called IntelliWrite(R), significantly reduced the I/O bottlenecks, eliminating fragmentation from the outset. This must-have technology has been integrated in Diskeeper products and is for a full I/O Server performance of computer systems of critical importance.
