Green Grid unveils four PUE categories
The Green Grid has unveiled four categories of PUE ratings, ranging from category 0 to category 3, according to its white paper: "Recommendations for Measuring and Reporting Overall Data Centre Efficiency." Each level's measurements become more granular and precise. So, for example, an IT manager opting for category 0 will require the least effort and fewest resources. However, results from a category 0 won't be viewed as being as precise as a rival's category 3 PUE. The Green Grid is a group of IT companies and professionals from around the world looking to increase energy efficiency in data centres.
