Maximising Your Virtualisation ROI
LONDON, September 15, 2011/PRNewswire/ --
- By Naveen Louis, Tech Support Specialist
Today, virtualisation is being utilised by many top enterprises to
maximise system resource ROI. It's certainly no surprise; CIOs are always
looking to strengthen that bottom line, and when multiple "computers" can be
run from a single hardware platform, that bottom line can certainly be
strengthened.
However, virtualisation comes with some major challenges of its own. For
example, capacity planning, when dealing with complexity in mixed
environments, becomes increasingly difficult. Resource tracking and
utilisation becomes a multi-headed hydra. Historical analysis becomes almost
moot when prime resources are constantly shifting and being reallocated.
Device failures, since they are utilised by multiple virtual machines,
trigger multiple alerts and tracking down the actual failure becomes an
interesting exercise.
A virtual infrastructure is dynamic and responds to the storage and
resource needs of the moment - but it must be kept healthy. Virtualization
is designed to make the most efficient use of the IT network investment, but
succeeds only when resources are shared efficiently without competing with
other guests sharing the same hardware. Here then, are three primary
barriers:
1. I/O bottlenecks occur from the continuous generation of unnecessary
split I/Os. As a result, the more a virtual platform is driven to produce,
the slower it responds.
2. Resource conflicts. Virtual machines compete for shared I/O resources
and have limited knowledge of actual hardware resource usage. Overloaded
disk I/O traffic from one VM will not only run slower, it will slow the I/O
speed of another VM.
3. Wasted disk space. Virtual disks set to grow dynamically will never
shrink when users or applications remove data. As a result, that physical
disk space cannot be allocated to other virtual systems. It also needlessly
increases time and resources necessary to perform backups for data
continuity and live migration to maintain optimal service levels.
To add to the above mentioned problems, new technologies like CDP, CSV,
Snap-shots and de-duplication are becoming common with SANs - you are more
likely to use a SAN as your backend storage in a large virtual environment.
Not to mention special Linked clones/differencing disks would be used when
you virtualise your desktop estate. In these situations you would need a
proactive approach to address this. A complete optimisation tool which would
write files contiguously in the first place would be ideal.
With Diskeeper Corporation's new V-locity 3(R) virtual platform disk
optimizer for VMware(R) and Hyper-V(TM), you have a fully integrated
software solution that gives the complete package for a fully optimised
virtual network. V-locity is compatible with new SAN technologies, requires
no scheduling and has no impact on system resources. Fully automated, IT
staff no longer need to spend unnecessary time attending to these inherent
problems, and can therefore spend time on other pressing issues. Best of
all, such a solution operates "on-the-fly" using only idle system resources,
which means you can get maximum ROI from your network.
