Data Center performance monitoring
Google uses the Power Usage Effectiveness metric to monitor the performance of its data centers. When it assess variability in its efficiency, Google takes action to remedy the defect. …

… “As we review our real-time efficiency performance we might, for example, notice that one of our data centers is not performing consistently with others of similar size and locale. So we’ll take a closer look at optimizing that facility. Are we using fans to cool spaces that don’t need to be cooled? Is the thermostat at the right set-point? Can we reduce the time the chillers need to run while keeping the machines operational? ” …

SuperNAP will use APC efficient power supplies
SuperNAP data center will leverage APC’s Symmetra uninterruptible power systems to provide 84 MVA of power and efficient power distribution units will supply the server racks. …

… “SuperNAP is situated several miles from downtown Las Vegas, an ideal location given both the large power quantities available to the facility and the favorable environment that eliminates the potential for a natural disaster. Unlike most centers of its kind, SuperNAP does not rely on raised floors or liquid cooling systems to cool its equipment; the facility utilizes a patented, industry leading HVAC design that allows it to provide as much as 1,500 watts per square foot – more than three times the industry standard.

APC Applications Engineers, along with Dennis Strieter, LDP Associates, the APC Manufacturers’ Representative, assisted in the design and implementation of SuperNAP’s tri-redundant power distribution system, installing three grids each contains color-coded equipment. The color-coding system ensures everyone has visibility into the power dependence throughout the facility. The colors red, blue, and gray represent the three independent sources and everything from the service entrance to the receptacles that feed the individual racks are painted to match the respective feed. ” …
