Data Center Infrastructure Efficiency (DCIE)
Data Center Infrastructure Efficiency (DCIE) is one of the popular performance improvement metrics used to calculate the energy or power efficiency of a datacenter. It is the percentage value obtained by dividing IT equipment power by total facility power.
Data Center Infrastructure Efficiency = IT Equipment Power / Total Facility Power X 100%
The higher the DCIE value the more efficient the datacenter.
The total facility power is the power measured at the utility meter. Whereas, the IT equipment power includes all the actual load of IT equipment like – servers, workstations, storage, switches, printers and other delivery equipment.
Given below is an example that will help you understand how to use DCIE metric in order to evaluate your datacenter’s electrical efficiency:
Suppose, Total Facility Power = 320 kW and IT Equipment Power = 160 kW
Using the formula DCIE = IT Equipment Power / Total Facility Power X 100%
DCIE = 160/320 X 100% = 50%
