Is this the data center metric for the 2030s?
When the PUE metric was first proposed and adopted at a Green Grid meeting in California in 2008, few could have forecast how important this simple ratio — despite its limitations — would become.
Few would have expected, too, that the industry would make so little progress on another metric proposed at those same early Green Grid meetings. While PUE highlighted the energy efficiency of the non-IT portion of a data center's energy use, a separate “useful work” metric was intended to identify how much IT work was being done relative to the total facility and IT energy consumed. A list of proposals was put forward, votes were taken, but none of the ideas came near to being adopted.
