I/O reduction software that guarantees to solve the toughest application performance challenges on I/O intensive systems like MS-SQL or your money back.
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. Not only can organizations expect an immediate boost and reclaim 30-40% of their storage IOPS, but many offload upwards of 50% of I/O traffic from storage for big performance gains in the 2X-10X range by simply allocating a little extra memory on key systems to better leverage V-locity for an even bigger benefit on MS-SQL workloads, Oracle, ERP, VDI, EHR (MEDITECH), Business Intelligence (BI) apps, CRM, Exchange, SharePoint, file servers, backup, and more.
Key Benefits
V-locity is a “set and forget” software utility that installs on Windows VMs (no reboot required) or physical servers and runs automatically in the background with near-zero overhead to the server. What little CPU cycles are needed runs at the 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 the 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.
Benefit Validation
The V-locity dashboard shows the value provided to any one VM or group of VMs by showing the percentage of read and write traffic offloaded from storage, total I/Os offloaded from storage, and how much “I/O time” is saved as a result. Admins can easily see the I/O capacity handed back to their storage subsystem from eliminating inefficiencies, see how much time that saves, and quickly identify key systems that would benefit greatly from V-locity’s caching engine by adding a little more memory.
