As the current infrastructure metrics promoted by The Green Grid (PUE and DCiE) have become more widely adopted, questions have arisen as to how to interpret individual results, compare different results for the same data center, or compare results across different data centers. Additionally, as there are various ways to calculate results, stakeholders in the industry have expressed concerns around the consistency and repeatability of publicly reported measurements. The Green Grid is publishing a set of rules and guidelines and a required process that organizations should follow when making public claims as to PUE or DCiE measurements for their data centers. This includes the definition of standard nomenclature that will enable an individual claimant to communicate key information about their measurements. With proper and transparent public reporting guidelines and availability of key information about reported results, both the credibility and usefulness of these metrics will be enhanced.
