35ENERGY EFFICIENCY ASSESSMENT OF DATA CENTERS USING MEASUREMENT AND MANAGEMENT TECHNOLOGY
Hendrik Hamann, Fernando Marianno, and Levente Klein
IBM TJ Watson Research Center, Yorktown Heights, New York, United States of America
35.1 INTRODUCTION
The energy efficiency of a data center (DC) is determined by implementation of best practices. Professional organizations like The American Society of Heating, Refrigerating, and Air‐Conditioning Engineers (ASHRAE) [1], Uptime Institute [2], and Green Grid [3] are providing recommendations to improve energy efficiency of existing facilities or to integrate energy efficiency in newly designed DCs. One of the major costs to operate data centers is cooling power to maintain safe operating environment for servers and IT equipment (ITE). There are currently few methodologies available for quantitative evaluation of the degree of best practice application to enable data center owners and operators to improve energy efficiency. A comprehensive method to quantify energy efficiency opportunities is presented; the method provides an understandable set of best practice metrics, as well as simple guidance to the data center operators and owners. The methods described can easily empower operators to rapidly translate general advice into actual cost‐effective customized solutions.
Specifically, we describe here a new monitoring solution based on spatial and temporal benchmarking of data center using the measurement and management technology (MMT) ...
