For Data Centers, energy efficiency is not just a “no-brainer,” it’s a requirement for survival. As of 2005, data centers around the world consumed almost 23 billion kWh (double the amount used in 2000).
With those kinds of energy requirements, even the smallest increase in efficiency can reap huge rewards. In an article posted on Earth2Tech this week entitled “Startups Go Wireless for Data Center Energy Management,” author Pedro Hernandez discusses a new report by Katherine Austin (“Green Data Center Design: Strategies and Players”) that delves into the “vital role of wireless energy monitoring and management systems, not only as a means of kicking off power-saving IT strategies, but also to sustain those efficiency over the long haul.”
Why is monitoring important? First, says Austin, because the data collected can “validate the effectiveness” of energy-saving strategies like a smart HVAC system. The sensors are also inexpensive and fairly easy to install. Finally, the data collected with these sensors can help a data center secure funding for even bigger energy efficiency projects. In northern California, for example, PG&E has set aside rebates totaling $50 million, designed to help data centers reduce their energy consumption.
Monitoring energy use in and of itself is not a new technique, but it’s the addition of wireless technology that’s adding the extra efficiency boost. Essentially, by wirelessly connecting sensors to a central control system, data centers can focus on “power-hungry zones,” and make more refined choices when deciding how to fine-tune operations for maximized efficiency. These wireless sensors can operate in a variety of ways—some monitor cooling data via “real-time visualization software,” while others use power strips embedded with microcomputer sensors.
