Overheard: Are data Center efficiency metrics purposely obtuse?

I have come to the realization that this industry does a wonderful job in telling its members WHAT to do, but lacks to follow-up with the HOW. Michael Manos, Struggling with CADE, McKinsey / Uptime Metric

Lots of buzz about the Uptime Institute’s symposium on IT Energy Efficiency and the study McKinsey released called Revolutionizing Data Center Efficiency . It’s interesting that Michael Manos estimates that only 10% of data center managers measure the efficiency of their facilities. Could it be because it’s almost impossible for the average Joe to get the data they need to plug in the formulas? Or could it be that they’re waiting for a clear winner in the proposed metrics? Try this one out for size: CADE.

CADE is the new metric-of-the-week.

CADE (Corporate Average Data center Efficiency) = (Facility Efficiency) x (Asset Efficiency)

Facility Efficiency is defined as (Facility Energy Efficiency) * (Facility Utilization)
Asset Efficiency is defined as (IT Energy Efficiency) * (IT utilization)
