Increasing demand for electricity in global computer data centers

San Francisco: According to an independent report from 20.5 to 2010 on electricity consumption in computer data centers, the http://www.aliyun.com/zixun/aggregation/31873.html "> As the global economy slumps and new energy-saving technologies emerge, the rising demand for electricity in computer data centers has finally come to an end.

Research shows that the power consumption of computer data centers has not increased as expected in part due to the 2008 economic crisis.

Research shows that Google's data centers are more efficient than most computer data centers.

A report by Professor Jonathan G. Koomey, a consultant at Stanford University's School of Civil and Environmental engineering, points out that the 08 financial crisis was due to lower demand for electronic systems, while server virtualization technology enabled fewer servers to run more programs, The actual number of servers in the 2010 was significantly lower than expected.

In 2007, the Environmental Protection Agency predicted the explosion of the internet and the socialization of computers, which would multiply the power consumption of computer data centers in 05 to 10, but in fact the reverse.

At the invitation of the New York Times, Mr. Koomey a new study called "2005 to 2010 increase in electricity consumption in computer data centers"; The study points to a notable increase in power consumption in global computer data centers, but only a 56% increase in 2005-2010. In the United States, electricity consumption grew by only 36%.

"Mainly because of the recession, and because of improvements in the design and operation of these electronic devices, the server power consumption is not expected to grow fast, which is really a talk." "Koomey said.

Although Koomey cannot distinguish between recession and the effects of energy-saving technologies, the decline in power consumption is indeed surprising, as computer data centers, as hubs for storing data, are so important in modern life. It allows people to send and receive emails, web searches, online shopping, bank transactions, and corporate sales reports.

Moreover, during the period under study, many services based on computer data centers, such as cloud computing and streaming media music and streaming media films, were popular.

In August 2007, the EPA released an influential report, predicting that from 2005 to 2010, the country's computer servers and computer data centers increased energy consumption by one-fold, to about 100 Billion-kilowatt a year, costing 74 billion of dollars.

Industry advisers and CEOs agree to Koomey's new analysis, but they do not deny that the slow growth is temporary.

Jimmy Clidaras, Google's platform and infrastructure chief engineer, said: "The market is expanding, we are now working in the clouds, music is at home, and music is in the air." ”

"The data can explain some problems, but they don't mean that the problem is over," says Kenneth Brill, founder of Uptime Cato, a consultancy at Santa Fe, n.m. Of course, energy consumption is increasing, and everyone should pay attention to it. ”

The drop in power consumption is particularly important because it is in the middle of a large-scale building of the storage capabilities of computer data centers in the computer industry.

As demand for new Internet services and so-called cloud computing services is endless, stimulated by this, people are hot, the country's electricity more and more by the steady growth of computer data center consumption; cloud computing services are widely used in commercial computer data centers and large electronics companies such as Amazon, Apple, Google, Microsoft and Facebook.

But the latest report shows that electricity consumption in computer data centers around the world remained relatively low in 2010. According to reports, "the global electronic system consumes about the total power consumption of 1.1-1.5%, in the United States, accounting for 1.7-2.2%." ”

In an earlier paper, Mr. Koomey said that in 2005 the computer data center in the electronic system accounted for only about 0.5% of the world's electricity, including cooling and ancillary equipment, with a data of 1%. In the 2005, electricity consumption in electronic systems worldwide amounted to 171,000 MW of power plants.

As part of his research, Mr Koomey has a clearer picture of how Google can influence global power consumption, based on data previously published. Google has built a number of servers for its computer data centers, which are available for services such as Google search and YouTube, but Google has been tight-lipped about the number of servers.

In May, however, a Google executive reacted to Mr. Koomey, and the company's computer data center had an estimated 1% lower total electricity consumption than the Koomey report.

If the Google executive's estimate is correct, it will confirm the industry's general view that Google, despite its large computer data centers, is relatively more efficient than the industry's mainstream. The vast majority of data center designers choose to adopt standard industry equipment rather than some special equipment.
