Data center virtualization offers a more flexible and dynamic data center environment for providing maximum availability and high performance for both data and applications. With the increased use of virtual machines, data centers no longer consist solely of hardware. Benefits of virtualization include improved hardware utilization, more efficient energy use, and lower equipment costs. Configuring traditional servers is a lengthy process and deployment may take days. The live migration of virtual machines enables you to quickly setup and deploy servers to meet network requirements.
Before considering data center virtualization, it’s necessary to decide what type services will be virtualized. Categories for virtualization include server, application, storage, desktop, and hardware. A virtual data environment that is poorly planned can be less reliable and increase rather than reduce energy costs.
