Data Center Power Usage Efficiency (PUE)
ITS established a baseline power usage efficiency metric to manage its power consumption and underlining energy costs. This approach was established by the Green Grid as an industry standard in which the total facility power is divided by the IT load. The data center becomes more efficient as the number moves closer to 0. ITS Manning is considered between “average” and “efficient.” Because the design and purposes of each facility are different, the PUE between ITS Manning and ITS Franklin should not be compared with each other.
