High-speed development of green energy-saving trend in data center

In recent years, with the deepening of the information process, the global volume of data produced every year is also more alarming, according to IDC, an international data company, released in 2011, Digital Universe Study, global information volume will increase by one times every two years, which has greatly driven the construction and development of the global Data center. But the global climate is warming, energy is getting more tense, people are becoming more and more vocal about energy saving and emission reduction, how to build a green data center to save more energy, become the problem that the enterprise pays more and more attention.

In order to promote energy conservation and emission reduction in the data center, the Ministry of Industry's "industrial energy Saving" Twelve-Five "plan" clearly pointed out that 2015 data center Pue Value (power Usage effectiveness, is the evaluation of data Center energy efficiency indicators) need to drop 8%; National development and Reform Commission and other organizations such as " Cloud computing Demonstration Project "also requires the demonstration project construction data Center Pue reaches 1.5 below; February 1, 2013, the first local mandatory implementation of data center energy Management Standards-" Data center room Unit energy consumption limit "formally promulgated the implementation.

According to IDC's latest study, the total number of data centers in China has reached 510,530 in 2012, with a combined growth rate of 2012 to 2017 (CAGR) of 9.8%. At present, many data centers in the country cost more than tens of millions of dollars per year, and the trend of rapid rise. The rapid expansion of the data center scale will inevitably lead to a continuous increase in energy consumption in the data center, and if China maintains its current energy efficiency levels, by 2015, only the country's data centers would consume 1 of years of power generation in the Three Gorges plant.

Therefore, it is necessary and urgent to optimize the infrastructure of data center, realize real green energy saving in data center, further reduce energy consumption and improve operation efficiency of data center.

It is understood that the data center's green development involves many factors, including site selection, design, building materials, refrigeration, power supply, IT equipment, application systems and other all-round problems. For the internal data center, the data center mainly by IT equipment, refrigeration system, power distribution system, lighting and other related ancillary equipment, they are the main energy consumption elements of the data center. This is the energy consumption of IT equipment accounted for a large part of the entire data center, therefore, to achieve the best energy saving, reduce the server and other IT equipment power consumption, is the most effective way. The new cloud storage integrated machine A8000 in Nanjing is the world's first 64-bit ultra-low-power high density storage server, with its 3 times times Energy saving, 5 times times capacity, 10 times times cost-effective to win the traditional storage products, can effectively solve energy problems, reduce data center operating costs, realize the concept of green data center.

Nowadays, green energy conservation has become an important development direction of data center, not only meet the interest demand of enterprise development, but also meet the needs of national energy saving and emission reduction work. Experts predict that by 2016, the Global Green data Center market will grow by three times times to $45.5 billion trillion. How to build more efficient and greener data centers is both a new challenge and an opportunity.
