Wireless network helps meet data center efficiency goals
Nov. 9, 2009
A wireless monitoring system provides
continually updated information on a data center's
electrical usage and thermal status.
A new monitoring system for data centers 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 data center 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. From the system dashboard, users can drill down to specific data centers and specific racks within a data center, and bring up side-by-side views of various factors, such as energy usage vis-à-vis indoor and/or outdoor temperature. Alerts can be generated when heat- and energy-use thresholds or user-defined financial thresholds are exceeded.
