Corporate average data center efficiency (CADE) is a metric used to estimate and rate the efficiency of an organization’s data center or centers. It was introduced by the McKinley consulting and Up Time institute as unit of measurement to check the energy consumption and the efficiency of an organization’s data center in comparison with other data centers. CADE measures total data center efficiency as a percentage. The higher the percentage, better is the proficiency of the data center. The calculation goes this way:
CADE= IT Asset Efficiency (ITAE) x Facility Efficiency(FE) where facility efficiency (FE) is equivalent to facility energy efficiency multiplied by facility utilization and asset efficiency (AE) is equivalent to IT energy efficiency multiplied by IT utilization.
CADE may also be used to monitor the performance of a data center, measure the performance of different data centers with each other and estimate the ROI (return on investment) in every green computing initiative.
