V-locity eliminates the two big I/O inefficiencies in a virtual environment that generates a minimum of 30-40% I/O traffic that is nothing but mere noise dampening performance and unnecessarily chewing up precious storage IOPS.
V-locity is a “set and forget” software utility that installs on Windows VMs (no reboot required) and runs automatically in the background with near-zero overhead to the server. What little CPU cycles are needed run at lowest priority so as not to interfere with server operations in the event that CPU cycles are needed by other applications.
V-locity’s patented write optimization eliminates the severe inefficiencies in the hand-off of data between the Windows OS and underlying storage that generate excessively small, fractured, random writes and reads that dampen performance. By providing Windows with the intelligence to write large, clean contiguous files in real-time, maximum payload is carried with every I/O operation to boost storage performance.
V-locity further reduces I/O to storage with its second patented engine - a DRAM read caching engine that serves hot reads from idle, available DRAM. Nothing has to be allocated for cache since V-locity dynamically adjusts moment-by-moment to only what is otherwise unused, so there is never an issue of memory contention. Many systems serve 50% of read traffic from DRAM if there is just 4GB of available memory that can be leveraged for cache. If a system is memory constrained, V-locity's caching engine backs off entirely.
