A major concern with virtual guest operating systems in a virtualized environment is the possible resource contention introduced as each virtual guest operates independent of the others.
With respect to storage, Diskeeper Corporation’s V-locity 3.0 virtual platform disk optimizer mitigates over-utilization in two ways:
First, each V-locity Guest installation coordinates resource scheduling with a centrally installed V-locity Host Agent. These guests automatically discover the V-locity Host Agent following installation. Once connected together in this fashion, V-locity Guests cooperate to complete each of their defragmentation tasks in a manner most efficient to the virtual server's resources as a whole.
Second, the automatic zeroing of free space feature ensures that unused space on virtual drives is zeroed out and compacted in such a way that when a virtual guest is migrated to a different virtual server via VMotion, only the allocated data is transferred. This speeds up the VMotion process and decreases the load on the shared storage subsystem.
RainWorx specializes in Online Auction Software. Our hosted web sites are mostly our Auction Software customers. As such, every auction listing (for each customer, on each server) has one or more images associated, so we have a very high volume of images being uploaded which could potentially create a lot of fragmentation.
