Corporate average data center efficiency (CADE) is a performance metric used to evaluate and rate the overall energy efficiency of an organization’s set of data centers. CADE makes it possible to calculate and measure a data center’s energy consumption based performance and compare it to the performance of other data centers.
CADE was initially introduced by Up Time Institute and McKinsey Consulting in an effort to provide a single metric as a means of identifying data center power consumption and efficiency. CADE is calculated using the following equation:
CADE = IT Asset Efficiency (IT AE) x Facility Efficiency (FE)
IT AE= IT energy efficiency x IT utilization
FE= Facility Energy Efficiency x Facility Utilization
The higher the CADE value the more energy efficient a data center is.
Moreover, to improve the value of CADE, some measures are taken to improve both the IT asset efficiency and the facility efficiency. For example, removal of old/dead servers, sever virtualization and demand management improves IT asset efficiency, while load reduction, better cabling and efficient cooling management can improve facility efficiency.
