All computers suffer from file fragmentation, but virtual systems suffer twice as much, fragmenting at the host and guest levels. Compounding this, by consolidating four or five servers into one, a single storage device is forced to work overtime by four or five times the increase in I/O traffic.
This results in heavy processing bottlenecks. Now, it seems, there’s a fix: Diskeeper Corporation’s V-locity virtual platform disk optimiser eliminates the problem by “invisibly defragmenting files and consolidating free space” on every Windows system on which it is installed, according to the makers. And that’s just for starters . . .
Since multiple virtual machines share mutual system resources, that “sharing” turns into competition (i.e., a performance hit). V-locity addresses this issue by fully synchronising the activity between host and multiple guest operating systems. In other words, in addition to defragmenting, it optimises peak server performance and reliability to the entire virtual platform, says Diskeeper.
When virtual hard disks (VHDs) are set to dynamically grow, they do not later shrink when users or applications remove data. This bloat wastes space that could otherwise be allocated to other virtual systems. Diskeeper says V-locity makes it easy to eliminate VHD bloat by providing an intuitive UI showing how much each virtual disk can be compacted, and the tools to easily do it. This allows system administrators to efficiently allocate storage resources on Windows Server 2008 Hyper-V deployments.
