Arch Rock Energy Optimizer-Data Center Edition (AREO-DC) is the first solution to measure both power and cooling system efficiency in the data center using non-disruptive Internet Protocol (IP)-based wireless sensor networks. It lets data center managers:
"baseline" the data center against American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) benchmarks for temperature/humidity/air quality, as well as for actual dollars spent on energy and its carbon equivalent;
identify the factors that cause energy waste (e.g., short-cycling, missing blanking panels, sub-floor obstructions) or "hot spots" and other harmful conditions, and correct these problems to reduce existing power consumption or allow the facility to support more equipment;
optimize available capacity for new servers based on the actual electrical/cooling consumption of equipment, rather than the overstated "nameplate" ratings.
How Energy Optimizer Works in the Data Center
AREO-DC works by deploying wireless sensors to measure electrical, thermal, flow and pressure conditions on power circuits, server racks, computer-room air conditioners (CRACs) or air handlers (CRAHs), chillers and underneath the raised computer-room floor. The sensed data is then transmitted via wireless sensor networks to a graphical, multi-window dashboard that shows the electricity load (and associated utility rate-adjusted spend rate) of various equipment, electricity usage by physical or functional area over user-selected time intervals; temperature and humidity data from CRACs, CRAHs, server racks and chillers over time; chiller water-flow rates; "heat maps" superimposed on a floor plan; and key performance indicators such as the Green Grid organization's Power Usage Effectiveness (PUE) Level 3 standard.
