Cures Pains from I/O Bottlenecks, Slow VMs, Slow Migration, Resource Conflicts,
Wasted Storage Space and Slow Backup Speeds
Diskeeper Corporation announced at VMworld the release of new V-locity® 3 virtual platform disk optimizer for VMware®.
V-locity 3 delivers invisible background optimization to give maximum I/O performance on virtual servers.
V-locity 3 now has full integration with VMware ESXi as well as existing support for other platforms such as ESX, and Microsoft Hyper-V™. Other developments include V-Aware™ technology which detects external resource usage from other virtual machines on the virtual platform and eliminates resource contention that would otherwise exist on the same Host Server. New CogniSAN™ technology detects external resource usage within a shared storage system, such as a SAN, and allows for transparent optimization by never competing for resources utilized by other VMs over the same storage infrastructure. CogniSAN does this without intruding in any way into SAN-layer operations. Lastly is the new automatic zeroing of free space which is a powerful engine that zeros out unused data blocks on virtual disks and makes virtual disk compaction easy.
