The True Cost of Overcooling Data Centers

摘要

Hardly a day passes now without a new article discussing Green IT or the critical issues of Data Center power and cooling. In a nutshell, computing has become cheap, while electricity has become both expensive and more difficult to get. With USD200 oil around the corner, as well as the need to reduce carbon footprints, the pressure to improve Data Center efficiency grows. IT equipment consumes 50 percent of the energy in Data Center. Cooling is interrelated to IT load and consumes another 40 percent. Both the IT demand and cooling support need to be addressed to solve the problem. What steps can Data Center operators take, safely and with no risk, to improve energy efficiency?
