Power Usage Effectiveness (PUE) and its reciprocal Data Center infrastructure Efficiency (DCiE) are widely accepted benchmarking standards proposed by the Green Grid to help IT Professionals determine how energy efficient data centers are, and to monitor the impact of their efficiency efforts. The Uptime Institute also has a comprehensive benchmark it recommends named Corporate Average Data center Efficiency (CADE). At their February 2009 Technical Forum, the Green Grid introduced new benchmarks named Data Center Productivity (DCP) and Data Center energy Productivity (DCeP) which probe into the useful work produced by your data center. All benchmarks have their value, and when used correctly, they can be a useful and essential tool for improving your data center energy efficiency. What is DCiE?
PUE / DCiE are efficiency benchmarks comparing your data center’s infrastructure to your existing IT load. The initial benchmarking of PUE / DCiE yields an efficiency score and sets a testing framework for the facility to repeat. Comparing initial and subsequent scores, data center managers can gauge the impact of what should be ongoing efficiency efforts. At any given time, they are comparing the power currently used for the IT equipment a company needs with the power used by the infrastructure which keeps that IT equipment cooled, powered, backed-up, and protected. PUE Example: Having a facility that uses 100,000 kW of total power of which 80,000 kW is used to power your IT equipment, would generate a PUE of 1.25. The 100,000 kW of total facility power divided by the 80,000 kW of IT power. DCiE Example: Having that same facility that uses 100,000 kW of total power of which 80,000 kW is used to power your IT equipment, would generate a DCiE of.8.
The 80,000 kW of IT power divided by the 100,000 kW of total facility power. Generating PUE / DCiE is only a start on your path to efficiency. For this benchmark to be meaningful it should be generated on a regular basis and preferably also on different days of the week and at different times of the day. The goal being to take actionable efficiency actions based on your actual data. By comparing your starting benchmark with benchmarks taken after implementing changes, you should be able to see noticeable improvements in your PUE/DCiE. Reduce your operation costs by utilizing measurement, benchmarking, modeling, and analysis to improve your Data Center’s energy efficiency.
PUE = Total Facility Power / IT Equipment Power DCiE = IT Equipment Power / Total Facility Power PUE DCiE Level of Efficiency 3.0 33% Very Inefficient 2.5 40% Inefficient 2.0 50% Average 1.5 67% Efficient 1.2 83% Very Efficient. DCiE and PUE Wars and Green Washing what PUE isn’t! You may have heard the terms “PUE Wars” or “PUE Marketing.” The Green Grid, the author of both PUE and DCiE, didn’t intend for either metric to compare one facility to another.
