Green IT refers to an attempt to reduce the impact of IT
operations on the environment.
Green IT starts with manufacturers producing
environmentally friendly products and encouraging IT departments to consider
more friendly options like virtualization, power management and proper
recycling habits. Green IT projects may have other benefits also however they are
generally geared towards showing considerable enhancement in energy efficiency.
Virtualization can be a wonderful ally in our efforts to
implement Green IT. Servers use energy and give off heat irrespective whether
100 % or 15% utilized. Virtualization is a technology designed to enable
multiple application work-loads each having an independent computing
environment to run on a single machine. This eliminates the approach of
dedicating a single workload to a single server a practice that yields low
utilization rates and allows virtualized servers to function near maximum capacity.
With virtualization, you can consolidate the workloads
currently running on a multiple underutilized servers onto fewer, more
efficient servers and begin to realize possible savings and efficiencies that
have been difficult to achieve previously. When virtualization is coupled with
the green design of new server and storage hardware, offers an effective
solution for keeping operational costs and energy demands in check.
