PUE Reconsidered - AFCOM Regional Meeting

James Cerwinski
July 31, 2009

Data Center Efficiency Solutions Consultant - Henry Hsu - Presented an insightful take on the utility and the limitations of Power Usage Effectiveness (“PUE”) as a data center efficiency metric. His thought leadership presentation covers:

• Historical Basis for PUE – what is the problem?
• Strengths of PUE Metric – what does it measure?
• Weaknesses of PUE Metric – what does it omit?
• Bottom Line: How to be Strategic About Datacenter Efficiency

I suggest you view it to at least find out how HenryandhisCat.com achieved a prefect PUE of 1.0. Do you know the PUE of your lab or data center? if so what is it?
