"Green energy saving" has become the main demand of data center

2012 China's cloud computing in the rapid development period, the nationwide Cloud Computing center landing work is in full swing. According to IDC's latest data on China's data center, the total number of data centers in China has reached 504,155 in 2010, with a total market size of $9.2 billion trillion. IDC also predicts that the market will continue to grow at double-digit rates from 2010 to 2015, reaching about $15.7 billion by 2015. Behind the data center of building construction, it maps out a series of problems, such as high energy consumption cost, difficult upgrade and maintenance, disaster tolerance and so on.

At present, many of the domestic data centres cost more than tens of millions of dollars per year, and the trend of rapid increase. The total power consumption of China's IT products in 2007 is about 30 billion ~500 million kwh, almost equivalent to the Three Gorges power generation total of one year. According to a new 2008 study by McKinsey, the global data center's energy costs amounted to $8.6 billion trillion in 2007, and the total energy cost in 2010 is expected to reach $11.5 billion trillion. "Green energy saving" has become the main demand of data center.

A few days ago in the first China cloud Computing conference published by the Nanjing Cloud Storage Technology Co., Ltd., Intel, China Electronics Technology Group 32nd Research Institute jointly developed the first largest capacity PB-class cloud storage System----based on the IA architecture of the cloud storage machine, with its 3 times times Energy saving, 5 times times capacity, 10 times times cost-effective, breakthrough the density cloud storage products limit, is the world's first 64-bit ultra-low-power high-density storage server, many advantages to win over traditional storage products. The large-scale deployment of PB-level cloud storage system will effectively solve the energy consumption problem, reduce the operation cost of data center and realize the idea of green data center.

Enterprise requirements focus on saving the overall cost, improve it efficiency, but also on the data center reliability and availability of higher requirements. If the core data center of the system failure, power outages, paralysis and other unexpected conditions, will cause the organization's business standstill, to the enterprise operation brings huge economic benefits of loss, and large-scale data center system upgrades and equipment maintenance and other aspects of the urgent lack of reliable solutions. At present, only telecommunications, banking and other industries to do better backup, the vast majority of enterprises in the face of major disasters for the rapid implementation of disaster recovery and business continuity, such as the lack of specific measures and countermeasures. PB-level cloud storage using a highly reliable redundant backup mechanism, each hard drive, motherboard, power supply, switch, master server redundancy between each other, any single node failure, will not affect the entire system operation. The system uses the high cost-performance storage service node, realizes the unified management and the fault tolerance through the Cstor system software, provides the high efficiency, the stable service. Compared with the use of dedicated servers, the system can save more than 5-10 times the cost of construction, and the larger the scale, the more obvious advantages.

With the rapid development of informatization, the construction of data center is urgent. It is urgent to come up with a set of more feasible solutions for the consideration of the enterprise's operational efficiency and resource utilization. As the server to the large-scale, high-performance, low-power, high-density performance of continuous innovation and optimization, the construction of data center is constantly exploring the best operation plan, in the "China's Year of cloud computing," in the comprehensive and perfect construction goal.
