10 Ways Energy Efficiency Is Driving Changes in Data Center Management

Cloud Adoption Is Moving Faster Than Expected

The use of virtualized environments and private clouds to maximize resource utilization is happening faster than most industry experts had expected. These infrastructures are becoming very pervasive in data centers today.


Managing reliability and power usage in old and new data centers is becoming an art form of sorts. Data center efficiency and energy management is continually morphing as new products and services become available, but it is seeing substantive changes in 2013. Coherently managing independent characteristics—including IT equipment availability, physical plant capability, software application performance, employee skills and capabilities, and external events such as adverse weather conditions and natural disasters, is not a task for the faint of heart. Plus, there are new standards with which data centers have to comply. Two new metrics, instituted by the Green Grid industry group, have recently become industry standards. The first is power usage effectiveness (PUE), which is the ratio of total facility power divided by IT equipment power. Ideally, it should be less than 2-to-1, and the closer to 1-to-1, the better. Then there is data center infrastructure efficiency (DCIE), which is calculated by multiplying total IT equipment power by 100, and then dividing the result by total facility power. A data center's DCIE should never be more than 1. Sources for this eWEEK slideshow are Power Assure CTO Clemens Pfeiffer, in addition to the Green Grid and AFCOM data center industry associations
