An article published in the NYT by James Glanz carried information on the percentage of power consumption by data centers in the U.S. It said that these data centers work for long hours and to their full capacity. About 90% of the power that is consumed by these data centers is not used adequately. Several data centers including that of Amazon have been fined for illegal installations. These data centers also use diesel fuelled generators that cause air pollution. The opponents of High Frequency Trading are going to be concerned about the usage of power by the IT firms and their exchange collocation facilities. Such green issues could seriously affect the trading of data centers. Glanz reports that Viridity, which tests data center server utilization found “in one sample of 333 servers monitored in 2010, more than half were found to be comatose. All told, nearly three-quarters of the servers in the sample were using less than 10 percent of their computational brainpower, on average, to process data.” The solution to such problems is not new.

the percentage of utilization of all its servers. It was found that some of the servers were not being used. They were left to run as nobody was sure of the operations, resulting in huge power losses. Then the tools were utilized to turn off and consolidate the servers. Glanz also reports that “In a typical data center, the energy wasted is as much as 30 times the amount of electricity used to carry out the basic purpose of the data center.” Data Center Talk updates its resources everyday.
