PUE: A Comprehensive Examination of the Metric
Via five earlier white papers from The Green Grid, countless public presentations, articles, and global harmonization efforts, Power Usage Effectiveness (PUE) has evolved from a simple fraction to a much more detailed description of how to instrument and analyze a data center's operations and infrastructure. The Green Grid recently released white paper #49, "PUE: A Comprehensive Examination of the Metric" as the single reference book for PUE. The Green Grid Vice President, Roger Tipley, was a content contributor to this "book" and he covered both the newly published PUE content, as well as refreshing everyone's memory about some of the older PUE material that may have been forgotten during the course of The Green Grid’s 6 years and 50+ white papers.
