Green Evaluation Metrics and Software Tool for Data Center

摘要

United States of America has the largest number of data centers while China and European Union are catching up rapidly. Data centers today do not have a standard measure to evaluate their level of green compliance or "GREENNESS". The report Congress on Server and Data Center Energy Efficiency Public Law 109-431 made by the U.S. Environmental Protection Agency Energy Star Program on August 2, 2007 urged the collaboration between government and industry to develop software tools for Data Center Energy effciency. Green evaluation metrics and software tool for data center are studied, planned and designed. In this study, we explore variables based on the 3Rs principle: Reusing, Reducing and Recycling and propose a set of metrics that combines all aspects of 3R from tier-1 to tier-4 data centers. A new metric evaluation for data centers is necessary for data centers to self-evaluate their level of greenness based on 3R so that those who are "GREEN" can then be given subsidies and vice versa. This paper also illustrates the architecture and the framework of the green evaluation software tool for data center and it is also known as GreenEval. It is a software tool to aim for benchmarking data centers using United States Environmental Protection Agency (EPA)'s online tool concept and objective. It aims to justify the data center green evaluation from quantitative perspective and operating cost perspective. The green evaluation software tool is also focus on assessing the performance implication of Reusing, Recycling and Reducing during periodic evaluation process.
