New system deals with the barriers to virtualised environments
1 min read
Demands for more network efficiency and lower operating costs are driving growth in virtualisation, but wannabe users are being warned of three barriers to adoption.
The alarm is being sounded by Diskeeper, which suggests that the problems have to do with the ability to share resources in virtual environments despite good virtualisation technologies.
It points to: I/O bottlenecks and performance degradation, created by accelerated fragmentation in virtual platforms; the problem that virtual disks that are set for dynamic growth don't shrink again, so waste the free space instead; and the inevitable competition between virtual machines for shared I/O resources.
Diskeeper claims that its new product, V-locity 2, is designed to optimise the virtual platform, using InvisiTasking technology that operates invisibly and without system resource conflicts.
It also harnesses IntelliWrite technology, so that the system prevents most fragmentation from ever occurring. And when it does happen, the system puts fragmented files back together so that they remain accessible and free space is consolidated.
That also minimises unnecessary I/Os passed from the operating system to the disk subsystem.
