The heat of cloud computing is driving more and more attention to data centers. And to build a good data center, good planning and design is the foundation. Deng, director of the IDC Engineering Design Research center of Guangdong Telecom Planning Institute, said that with the advent of cloud computing, data center planning and design concepts needed to be updated.





It planning first




The overall planning of the
data Center covers all aspects, including venues, utilities, it workloads, operational dimensions, and so on. Generally speaking, can be divided into two major levels, the first is the data center load capacity, the second is the infrastructure.





for load capacity planning, if the overall planning of it in the early stage of the project is not clear, it load planning is too large, may lead to late power air-conditioning and other infrastructure supporting serious deficiencies. Conversely, if the IT load planning is too small, although the short-term cost reduction, avoid redundancy, but will cause data center expansion difficulties, once the volume of business increase, due to lack of early predictability, will lead to the data center of the reconstruction, resulting in waste.





of course, absolutely just right is impossible, in fact, the data center load capacity planning, in the "Now" and "future" between as much as possible balance. So the first step in achieving a Green data center is to get a clear picture of the needs and costs of the budget.





Deng said that in the early days of the data center, first of all, need to do a feasibility consultation, clear the size of the data center and end customer target, whether it is an Internet enterprise, or financial enterprises, or enterprise enterprises. In the consultation planning stage, not only the communication experts involved, but also have the IT background of engineers, to ensure that the development trend of various industries, cloud computing, cloud storage, servers and other equipment is very well known. In the later stage, in addition to building decoration, fire tunnels, such as the decision by the architect, the core design should be decided by air-conditioning or power experts, from air-conditioning decision building planning.





to protect the power of the Mission





Power is the basic guarantee of data center operation, at the same time, with the requirement of energy saving and emission reduction, the price of electricity is directly related to the operation cost of data center. Deng points out that in the data center location phase, power supply should be one of the first tasks of data center planning, and must be signed with the local power supply department to ensure the safety of power supply. "We have a project on this issue, the power supply Bureau originally agreed, but then changed the leadership, the previous concessions to other enterprises." "In particular, there are now hundreds of acres or even thousands of acres of large data center park, Deng said, in the early stage of design needs to fully consider the power supply."





, manager of Shanghai Unicom's IDC and cloud Computing Operations Center, Tana Tari also raised the same issue. As an area of lack of electricity, power supply guarantee is very important to the operation of data center in Shanghai. With the search for electricity price concessions in Inner Mongolia and other data centers, "Shanghai has no concessions on electricity prices, the power company said, to ensure that the computer room has never been due to lack of electricity is the biggest discount." Tana Tari said that Shanghai Unicom will regularly visit IDC power supply to solve the problem of power supply in the process of IDC operation.





In addition to mains, how does ups balance reliability and energy efficiency? China Telecom operation and maintenance Department of senior Business Supervision Yang Shizhong proposed triangular 2N power supply mode, can increase the load rate of UPS more than 30%, easy to transform, maintenance is not complex, It can be used in a large IDC room with multiple AC UPS power supply systems or 240V DC power supply system.





communication industry at present, the general mode of UPS power supply is independent dual-bus mode, in the work of two independent systems to power equipment, when a device, a system problems, the other system to bear the load required by the full load. This is the so-called 2N power supply mode. In this mode, each system normally work with a low load rate, the maximum can reach 40%.





in triangular 2N power supply mode, the power supply is composed of a network equivalent to a triangle, each corner is built by UPS. The advantage of this triangular power supply method is that the band load rate can be increased from 40% to the limit of 60%, can be used three equivalent capacity equipment or systems with the original two conventional independent power supply system docking, can effectively reduce the cost of power equipment construction One-fourth.





determine the data center level in advance





Zhong Jinghua, Deputy chief engineer of China Electronic Engineering Design Institute, according to China's national standards, data center divided into a, B, C three grades. Species Hua points out that any data center must be graded before design, and the level is determined by the owner's own measurement of the importance of the data center. "If the network interruption will cause significant economic losses, according to the high level of construction, if it does not cause great losses, there is no need to build a high grade, so according to the business to determine the level." "Zhong Jinghua said.





Deng says there is a lot of uncertainty about the data center level, and that A and B requirements change anytime, anywhere. She pointed out that in the main equipment, A and B-class actual is similar, and in the end and space, in planning to take into account from B-level to a-level requirements.





in the construction of norms, due to customer-oriented, data center construction to meet the standard requirements are also different. At present our country data center must comply with three national standard first, namely gb50174-2008, gb50462-2008, d9dx009. At the same time, the United States Communications Industry Association Standard TIA-942 is also the practice of many operators reference.





Deng pointed out that the construction of data center in addition to comply with the building professional norms, but also the implementation of power system specifications and other local norms, as well as in accordance with the Internet, finance and other industries of different industries and special norms. In addition, after the Wenchuan earthquake, the data center structure of the professional norms have been more and more attention, the structure of the earthquake-resistant and load-bearing problems also need attention.





Number 2011 Service Operation Dimension





room Air-conditioning: The domestic market size of about 2.9 billion yuan, an increase of 11.9%, of which more than 30KW room air-conditioning overall proportion of nearly 70%.





UPS: The domestic market size of more than 3.5 billion yuan, the market concentration continues to increase, the top five enterprises total market share of more than 25%.





HVDC System: As of the end of November, China Telecom full network 240V DC power supply system up to 251, the total power supply capacity of more than 100,000 amperes.





Emerson Network Energy in China's computer room air-conditioning market still occupies an absolute advantage, its force bot, Haillos, Atlas three major brands add up the market share of nearly 45%. The Touze and the best attempt were divided into 二、三位, and the sales accounted for 12.2% and 10.9% respectively.





Eaton Power, Schneider Electric, Emerson Network Energy is still in the first echelon of UPS, Kehua, Crestec, easy to follow the principal, Huawei, ZTE and other communications giants may timing into the future.





high-voltage DC power supply system market is still in the initial stage, Emerson Network Energy, branch Huaheng, Tatsu electricity, Zhong Heng Electric, etc. is currently in the lead, Schneider Electric, Eaton power supply, etc. are still on the sidelines.
