TAILIEUCHUNG - Creating the Green Data Center

The continued thirst for energy is a recurring story in news headlines every day. Global warming forecasts rising temperatures, melting ice, and population dislocations due to accumulation of greenhouse gases in our atmosphere from use of carbon-based energy. There are strong arguments for and against the dire predictions of global warming, yet one fact is undeniable—over the past 10 to 20 years, the inhabitants of Earth are collectively consuming more energy at a faster rate than ever before. | Creating the Green Data Center Simple Measures to Reduce Energy Consumption Introduction Energy Awareness Driving Decisions in the DataCenter The continued thirst for energy is a recurring story in news headlines every day. Global warming forecasts rising temperatures melting ice and population dislocations due to accumulation of greenhouse gases in our atmosphere from use of carbon-based energy. There are strong arguments for and against the dire predictions of global warming yet one fact is undeniable over the past 10 to 20 years the inhabitants of Earth are collectively consuming more energy at a faster rate than ever before. No where is this more apparent than in the data center where power consumption has doubled in the past five years and is expected to rise at a steeper rate of 76 from 2005 to 2010. One culprit is steadily increasing power requirements for servers. For example according to IDC 2006 the average small to medium size server required 150 W of power in 1996. These small to medium servers will require over 450 W by 2010. Of course increased power requirements means increased heat to dissipate driving another culprit for increased energy use in the data center cooling. One survey of IT executives shows that 45 of data center energy consumption goes to chiller cooling towers and computer room air conditioners CRACs . According to IDC 2006 in the year 2000 for every 1 spent on new servers 21 cents was spent on power and cooling. By 2010 IDC predicts that every 1 spent on new servers will require 71 cents on power and cooling. This massive increase has led to the formation of industry consortiums such as The Green GridSM that are specifically focusing efforts on lowering power consumption in the data center. For some businesses increased energy costs are merely considered a cost of doing business. Yet there is a point at which these costs dampen profits and limit investment needed to grow and modernize a business. Worse are shortages of electricity .
