In the past, virtualization projects were implemented to reduce capital and operating costs through server consolidation. Now that virtualization is entering a more mature period of adoption, senior IT management is starting to question the efficiency of these virtualized datacenters. There is no doubt that a virtualized datacenter is more efficient than its physical predecessor; the question now, however, is whether the virtualized datacenter is operating at peak efficiency, minimum efficiency or somewhere in between. This issue receives significant focus when infrastructure directors request additional capital funding to expand their virtual datacenters.
This white paper explains why commonly used measures of efficiency are not actually helpful, and identifies the three critical measures of efficiency that should be used instead. The paper then outlines a methodology to assess and improve efficiency in your virtualized environment.
