New White Paper Urges Defrag for Virtual Environments

LONDON, September 28, 2010 - A new white paper, The Importance of Defragmentation in Virtual
Environments, co-authored by Osterman Research and Diskeeper Corporation,
demonstrates that virtual environments require defragmenting even more than
physical environments. This is due to the fact that virtual environments
support multiple operating systems and create a higher intensity of disk
activity.

"The need for defragmentation is even more acute in virtual
environments," the white paper states. "This is because physical hardware in
a virtualised storage environment must support more operating systems and so
can undergo even more disk access and more stress than in a non-virtualised
environment. Further, disk I/O in one virtual machine has a cascading effect
on disk I/O in other virtual machines, and so the problem of excessive disk
I/O in virtual machines is, in fact, even worse than what would be
experienced in a physical disk environment."

The white paper indicates that fragmentation, which reduces system
performance in a physical storage infrastructure, can even create more of a
performance loss in a virtual storage infrastructure. Virtual disks can
become fragmented over time just like the physical disk or disks on which
they reside. The result is a fragmented virtual disk on a fragmented physical
disk-or fragmentation within fragmentation.

This data is especially important in light of the rapid growth of virtual
environments. Organisations are particularly interested in virtualisation due
to its many benefits, which include reduced hardware costs, ease of adding
additional capacity to existing infrastructure, ease of administration and
maintenance, and simplified migration from one server to another.

Because of the complexity of I/O traffic in virtual environments, simple
defragmentation is not enough to fully address the fragmentation issue. For
that reason, Diskeeper Corporation has developed new technology for virtual
environments, found in their V-locity(TM) 2.0 virtual platform disk
optimiser. A recent product release for VMware and Hyper-V, V-locity 2.0 is
the first optimiser that truly eliminates the barriers to full virtual
efficiency. V-locity 2.0 employs IntelliWrite(TM) and InvisiTasking(R)
technologies to both prevent a majority of fragmentation in the first place
and to efficiently coordinate VM resources when defrag is running invisibly
in the background.
