Use Smart Grid for Data Collection Across the Environment

Sensors collect power and cooling data from systems and facilities and establish consistent energy benchmarks. This allows IT managers to aggregate information to provide meaningful data on power and cooling efficiency in real time, which can help dynamically manage data center energy usage.
Quantifying the power efficiencies of a data center may appear to be something pretty esoteric, but rest assured, it is all very scientific. There are two metrics, instituted by the Green Grid industry group, which are now beginning the lengthy process of becoming international industry standards: a) Power Usage Effectiveness (PUE): This is a ratio of total facility power divided by IT equipment power. Ideally it should be less than 2-to-1; the closer to 1-to-1, the better; and b) Data center infrastructure efficiency (DCiE):??í DCiE is a percentage: IT equipment power x 100, divided by total facility power. The bigger the number the percent, the better. A data center's DCiE should never be more than 1. To get these numbers in line, there are a number of things that data center managers can do over time. Here is a list of best practices to consider.
