In order to improve your data center’s energy usage, you’ll first need to know what it is. Industry research has shown that after IT equipment, a data center’s cooling system is the largest energy consumer. The irony of this is that many data center managers have no real visibility into their cooling system’s effectiveness or efficiency. This expert handbook explains how to set up a data center cooling monitoring system, looks at how increasing server inlet temperatures can optimize cooling efficiency and outlines methods for building hot-aisle/cold-aisle containment systems. The final segment details criteria for selecting and implementing economizers in your data center.
