10 Global Session Goal Desired Outcomes: Effective energy efficiency metrics that: 1. Measure the actual IT work output of the data center compared to actual energy consumption. It is of note that in the process to define IT work output, the following interim measurements are being defined and / or validated: a. IT - Measure the potential IT work output compared to expected energy consumption; and measure operational utilization of IT equipment b. Data center facility and infrastructure - Measure the data center infrastructure efficiency (PUE) 2. Measure renewable energy technologies and re-use of energy to reduce carbon 19 Global Consensus Achieved The United States of America, European Union and Japan Reach Agreement on Guiding Principles for Data Center Energy Efficiency Metrics: Harmonizing Global Metrics for Data Center Efficiency Goal: Share global lessons and practices with an objective of arriving at a set of metrics, indices, and measurement protocols which can be formally endorsed or adopted by each participant organization to improve data center energy efficiency globally. This includes the following specific goals: 1. Identify an initial set of metrics 2. Define each metric 3. Define the process for measurement of each metric 4. Establish on-going dialog for development of additional metrics 20 10

11 Global Consensus Achieved Guiding Principles The collective groups are in agreement on the following guiding principles, p as an interim step toward the desired outcomes (1. b.). It is recommended that data centers begin to measure PUE according to these principles: Power Usage Effectiveness (PUE) using source energy is the preferred energy efficiency metric. PUE is a measurement of the total energy of the data center divided by the IT energy consumption The industry should improve the IT measurement capabilities to ultimately enable taking the measurement directly at the IT load (e.g. servers). At a minimum IT energy measurements should be measured at the output of the UPS For a dedicated d d data center, total energy measurement should include all energy sources at the point of utility handoff. For data centers in larger buildings, total energy should include all cooling, lighting, and support infrastructure, in addition to IT load In addition to PUE, the bodies recognize the necessity of other metrics expressed in the desired outcomes (1.a. and 2.) 21 Next Global Task Force Step? IT Productivity Metrics There is significant interest and work among the bodies represented to proceed with globally accepted metrics and measurement protocols, from minimum i allowable to aspirational on the topic of data center efficiency. A taskforce has been formed with representatives from each participating body. The entire group of participants will reconvene once the task force feels the time is appropriate based on progress.
