Micro PUE. The Key to Data Center Energy Savings. by Robert Hunter and Chet Sandberg Most in the data center world have heard of the metric Power Usage Effectiveness, or PUE. PUE was one of the first metrics developed to give data center managers an idea of the energy efficiency of their operations as compared to others. [...]
A White Paper By Robert Hunter and Chet Sandberg The purpose of this paper is to examine the need for smart metering of facilities at the branch circuit level and determine if such implementations would pay back their investment. To begin with, a definition of the term “smart metering” is in order. The phrase smart metering is [...]
By Robert Hunter and Chet Sandberg Power monitoring in data centers has moved from a luxury to a necessity as heat and power densities have risen rapidly. The principal of Management By Information (MBI) states that: You can only manage what you measure. The first tenant of MBI is: The accuracy of your measured data directly impacts the [...]
By Robert Hunter and Chet Sandberg Data center heat density has been increasing since the advent of the server. This has become particularly problematic during the past few years as data center managers have struggled to cope with heat and power intensity problems. These issues have resulted in enormous energy bills and a rising carbon impact. The purpose [...]
With the ratification of the Kyoto Protocol in 2005, a new sense of environmental awareness has swept the globe. It is now understood that electricity and the burning of fossil fuels to create that electricity are a leading cause of climate change and pose a huge challenge to long-term energy sustainability. Data centers are one of the world’s largest [...]
