Microsoft Hyper-V® hypervisor virtualization brings
an entire evolution of new benefits to computing – including substantial hardware
resource savings, reductions in space and energy, and much more. There are several
issues which must be addressed, however, in order for virtual machines to deliver
the efficiency and service for which they are intended.
An enormous amount of I/O traffic is completely unnecessary—and the problem is exacerbated
in virtual environments. Facing performance bottlenecks, organizations respond by
investing in more hardware—trying to solve performance issues reactively, rather
than applying an efficient approach. By optimizing I/O at the source, before it
gets pushed through the server, network and storage, performance issues are eliminated
across the infrastructure at a fraction of the cost of hardware.
VM™ uniquely addresses the unnecessary I/O patterns of
reads and writes by aggregating data on writes to perform sequentially while caching
reads on available server memory without contention to the application. As a result,
V-locity boosts application performance by 50% or more by (1) maximizing the efficiency
of every single I/O from write requests that leave the server and (2) caching the
most active data from read requests using available server memory.

How Are Hyper-V Platforms Optimized?
V-locity’s IntelliWrite® technology automatically prevents the operating
system from breaking files into pieces and writing those pieces in a performance-penalized
manner. This proactive approach improves performance up to 50% while preventing
any impact to advanced storage features like snapshots replication, data deduplication
or thin provisioning growth.
Unnecessary I/Os are eliminated, resulting in faster I/O throughput, and the ability
to add VMs without a drop in performance. With IntelliMemory™ caching
technology, V-locity VM also uses RAM cache to greatly improve file reads performance,
while lowering the number of drive I/Os created. Combined, the additional benefits
of these technologies include increased VM density, increased platform reliability,
improved application performance, lower operating costs and increased
"We were experiencing longer and longer response times from servers in our Hyper-V
environment. After installing V-locity, we've noticed a performance increase in
the desktops and a large gain in our Hyper-V environment."
