White Paper: Virtualizing For Top Efficiency Takes Strategy

Source: Diskeeper Corporation

Intense demands for network efficiency and lower operating costs are driving the phenomenal growth of virtualization. Yet, despite outstanding virtualization technologies, the ability to effectively share resources in virtual environments runs into three barriers:

  1. I/O bottlenecks and performance degradation created by accelerated fragmentation - the action of breaking up a file into pieces and writing it to scattered locations on the disk - in virtual platforms.
  2. Virtual disks that are set for dynamic growth don't shrink again when data is deleted. They waste the free space instead.
  3. Virtual machines compete for shared I/O resources and their use is not effectively prioritized across the platform.

A new product from Diskeeper Corporation, V-locity 2, optimizes the virtual platform using the new InvisiTasking technology that operates invisibly and without system resource conflicts. Then utilizing IntelliWrite technology, V-locity 2.0 also prevents most fragmentation from ever occurring. When fragmentation does happen, V-locity puts the fragmented files back together into one piece so that the files are more immediately accessible while also consolidating free space. In so doing, it minimizes unnecessary I/Os passed from the operating system to the disk subsystem, beating all previous standards for I/O performance and reliability.
