What is DCiE (Data Center infrastructure Efficiency) and how does it relate to PUE?
-
A
DCiE is the inverse of PUE expressed as a percentage, showing what fraction of power reaches IT equipment
-
B
DCiE measures the efficiency of individual servers rather than the overall facility infrastructure
-
C
DCiE replaces PUE as the primary efficiency metric specifically for Tier IV certified data centers
-
D
DCiE measures the ratio of cooling power consumption to total IT equipment power consumption
