In recent years, data centers have been deploying server and storage virtualization technologies to more efficiently use underutilized computing assets and to create more flexible infrastructures. In decoupling the logical function from the physical hardware, virtualization allows hardware to be pooled and shared, thus improving utilization. Once in place, virtualization makes new server or storage deployments much quicker and easier, while making it easier to effect changes to the existing infrastructure.
