Airsys proposes the PCE metric in an OCP paper

Airsys Cooling Technologies proposes a new metric, PCE (Power Compute Effectiveness), in a paper for the Open Compute Project, used to measure the proportion of provisioned power in a data center that is actually available for computing, rather than the portion consumed by supporting systems such as cooling and power distribution. The paper gives an example: if 70 MW of a 100 MW facility can be used for computing, the PCE is 0.70; by retrofitting to reduce the supporting load to 20 MW, the PCE can be raised to 0.80 without increasing total power. The two examples given in the paper are 0.705 for a 20 MW colocation site and 0.79 for a 100 MW hyperscale campus, and it notes that there is currently no industry average.
