Determining PUE in an imperfect world

Figuring out PUE is simple in principle, but surprisingly painful in practice. If you have experienced any one of the following scenarios, then you need to read Dr. Jay's technical tip now!
  • Can't measure data center heat load, but have good electrical sub-metering...
  • Water temperature is easy, but can't install a flow meter...

OpenData, a leading Data Center Information Management (DCIM) tool, collects, normalizes, monitors and analyzes performance data from all of the power, cooling and mechanical equipment in critical facilities. The operational intelligence it provides helps IT and facility managers improve decision making, cut costs, and identify ways to improve infrastructure throughput and capacity.
