Saving with Server Virtualization

Number of servers in an enterprise increase with the growth of the
organization. With slowdown effecting everyone, the first thing for an
enterprise to use is their existing infrastructure as much as possible, before
they plan to buy any new hardware. Since servers are rarely utilized to their
maximum levels, this is where server virtualization can help. Server
virtualization itself now doesn't need any introduction. Virtualization has
grown so much over the past couple of years that, whenever deploying a new
server, first thought is to deploy it as a VM.

Sever virtualization offers many benefits, as you are using your existing
server, you can easily save on the costs which you would have spent on new
server. With existing server being utilized optimally, you also save on power,
deploying a new server will consume more power, than using existing ones at
optimum levels.

Another benefit of server virtualization is flexible resource allocation. In
case you find that one of the servers in the virtual environment doesn't need so
many resources, you can take them away and reallocate to another server that
really needs them.

This could be RAM, storage space, network interface or a number of other
things. All this can happen dynamically without bringing down the physical
server.

Server virtualization is also considered a green technology. As you won't be
deploying new server, you will be reducing carbon emission to atmosphere.
Consider these stats given by Microsoft on its website “a server setup of
Standalone IIS x 10 results in 34,084 Kg of CO2 and after server virtualization,
a setup of One Hyper-V server with 10 IIS7 VMs results in only 3,491 kg of CO2.
That's a saving of 30,593 kg of CO2 emission into the atmosphere. Just in case
you are curious about reductions you can achieve in terms of power, CO2 and
money, go to http://www.hyper-green.com/.
