Green communication: HVDC, cloud computing from pilot to scale application

Operators as an important support for social informatization, "Twelve-Five" period will vigorously develop broadband and mobile internet services, and continuously expand the scale and capacity of the network, which will bring about the rise in total energy consumption, energy-saving emission reduction work is still a huge pressure. As a result, operators are planning to increase energy-saving inputs for 2012, and some of the energy-saving technologies and programs that have been fruitful in 2011 will be deployed in 2012. According to the development trend of energy-saving technology next year, several experts said that from the whole network to see the various aspects of energy-saving technology is very much, but cloud computing, High-voltage DC Power (HVDC), modular data center and other technical programs will be the mainstream of development in the 2012.

High Voltage DC power technology will be widely used

High-voltage DC Power Technology is the use of High-voltage direct current (240V DC voltage level) directly to the data center IT equipment power. The advantages include that the system's parallel rectifier module and battery group all constitute redundancy relationship, which can greatly improve the security and reliability of the system, and the load rate of rectifier module is kept at a high level, so that the conversion efficiency of the system is maintained at a high level. The input power factor of the switching rectifier module can be increased to more than 0.99, and the carrying capacity is greatly improved, and the cost of construction investment and operation dimension are reduced effectively.

A few years ago, when operators were pushing the High-voltage DC power supply Technology, the industry chain parties did not agree. 2011 The technology in a number of successful pilot scale, so that the three major operators and power supply, IT equipment manufacturers from the initial wait and see into the current strong support.

According to the senior steering Yang Shizhong of China Telecom Network Transportation Department, by the end of November 2011, the 240V DC power system has reached 251, the whole network uses 240V DC power supply IT equipment has more than 46,000 units, the application range is distributed in 19 provinces, 73 regions. Cannan, deputy general manager of China Unicom IDC Operations Center, said that the High-voltage DC power supply has a huge advantage over the traditional UPS power supply, with the elimination of some constraints, High-voltage DC power supply technology will be in the next generation of large-scale commercial data center. The

Cloud computing implementation of "End-to-end Green"

Cloud computing technology can achieve resource sharing, reduce the efficiency, improve resource utilization, to a large extent, the operator's own network energy consumption. At the same time, operators to set up cloud data Center for enterprises to provide computing and storage services, but also to help enterprises greatly reduce the server, room space, energy costs of investment.

At present, the three major domestic operators have seen the advantages of cloud computing technology applications, in 2011 to open cloud computing strategy or a larger scope of the pilot. such as China Telecom in 2011 issued "Sky Wing Cloud Strategy", one of the purposes is to achieve energy saving and consumption.

2012 will be a key year for operators to deploy cloud computing. "According to a person in China Telecom, China Telecom will be the unified construction and deployment of the national, industry-leading cloud computing data center," Twelve-Five "will have the ability to provide millions of high-performance virtual host, by this, China Telecom will further optimize the telecommunications network, enhance network capabilities, effectively reduce their own and social energy consumption.
