The development of computer network technology has attracted people's attention to the basic application support platform. How to establish a standardized and applicable design concept for the computer room of the university network control center has also become a new topic. For the university campus information system, e-library, network teaching, network office, network examination, network teaching affairs, etc. are all based on the information network, and the network control center computer room has become the core hub of the entire school computer system equipment. Therefore, how to plan the construction of the network control center's computer room scientifically, standardizedly, and safely to ensure the safe, reliable, and stable operation of the integrated computer system has become a new topic. Network Control Center Computer Room Values In this regard, international analysis is carried out from three aspects: direct economic value, indirect economic value, and comprehensive significance. Here we also analyze the values ​​of the construction of the computer room from the above three aspects: 1. Direct economic value As a technological product, the network system equipment must have a certain service life, scope of application, and expensive purchase value. When the user fully meets the application environment of the purchased device, the theoretical purchase value to service life ratio is the application consumption value rate. Established, and when the user fails to use and maintain the operating environment requirements of the purchased equipment, the purchased value of the investment remains unchanged, the service life will be shortened, and the consumption value rate will increase. 2. Indirect economic value Due to the malfunction of the computer system, the direct loss cost in the United States was as high as 17 billion US dollars last year. It is difficult to express the indirect loss in economic figures. The application of computer systems in our country is in its infancy, but the state of system failure is not optimistic. 3. Comprehensive meaning The safe, stable and reliable computer system operation depends on the reasonable and economic network control center computer room project, which is also a comprehensive reflection of the modern information management level of colleges and universities. Three elements of design System standardization: The design and project implementation of the computer room of the university network control center must first carry out a comprehensive design in accordance with China's existing codes and standards; secondly, the design of the computer room should be considered from a multi-systemic perspective. The computer room of the university campus network control center is not just a place for simple computer network equipment, but a power supply and distribution system, integrated monitoring system, integrated wiring system, independent air conditioning system, gas fire extinguishing system, dedicated ground system, and structure. Decoration system, anti-surge protection system, security access control system, BA system and other comprehensive system projects, each system is not isolated from each other, but is closely related. For example: the power safety of the host depends on the high-quality output of the UPS, and the high-quality output of the UPS depends on the layers of "filtering" (steady current, voltage regulation, anti-wave, frequency filtering) and N, PE lines before the mains input The stability of the N and PE lines is based on the stability of the resistance of the independent ground system and the joint ground system. The good stability of the ground system depends on scientific, reasonable and standardized design and construction. Good construction requires experienced field engineers, carefully controlled material purchasers and excellent construction personnel. In order to ensure the stable, reliable, and safe operation of computer hosts, networks, and other equipment, it is necessary to comprehensively consider the systematicity of the operations between the systems in the computer room of the network control center. Economic applicability: The determination of the computer room area, area and performance index of the university network control center must be based on the current environment of the university's computer network system and the requirements for the integrated environment of each host device within the next five years, with appropriate advances. At the same time, the computer room system engineering of the university network control center should avoid excessively increasing the total investment of the project due to the excessively high equipment, facilities, scale and grades brought about by the setting of the computer room comprehensive environment and technical parameters. Generally speaking, the overall design plan is based on comprehensive consideration of the business development requirements of universities in the next few years, and the five-year planning and design is made under the premise of meeting the development of network communications. Beautiful and comfortable: The network control center computer room serves as a collection center for school information, business, and management. It is a window for electronic technology and network management operations. It serves as a collection point for comprehensive data. The workplace of development managers also needs to meet certain aesthetics. And comfort. Therefore, it is necessary to divide the existing use area of ​​the machine room to be built, from the applicable point of view to achieve the purpose of highlighting key areas, ensuring full use of functions, broadening the view of the overall machine room area, and facilitating observation and management; followed by reasonable configuration and use The special decoration materials for the machine room make the network control center machine room beautiful and comfortable after completion. Four basis for design Considering various factors comprehensively, the design requirements should be specifically reflected from the following aspects: The computer room project of the university campus network control center is designed according to the "National Standard" Class A standard. For the computer room environment of the university network control center after completion: from the aspects of temperature, humidity, dust cleanness, illumination, noise, anti-interference (shielding), anti-static capability, etc., according to internationally mature advanced technology, higher than the national standard The parameters require system design. For the monitoring of automation equipment, the UPS host, power supply and distribution management cabinet, precision air conditioning, water leakage detector, emergency lighting power supply and fire protection should be provided with operating status display and warning alarm design in the network control center computer room. On the premise of ensuring the special materials for the network control center computer room, a large part of advanced lightweight, antistatic, flame retardant, dust-free, easy to clean, non-polluting and environmentally friendly materials are selected to make the network control center computer room beautiful and elegant after completion. , Pleasing effect. Design three processes Starting from the data process, arrange the server room, network room, and management room in adjacent positions, and in the host area to minimize the distance between data reception and processing and then sending. Starting from the power flow and management, the main power cabinet of the UPS machine room is supplied to the main power cabinet of the building → UPS host → UPS power control cabinet → each host device, which lays the foundation for improving work efficiency. Designed from the action flow, the staff enters the buffer zone to change clothes, change shoes to the terminal computer room to work on the computer → small computer server computer room to work on the computer → network computer room debugging → UPS computer room power control → I / O computer room to work on the computer → air-conditioning Maintenance to work in the system analysis room → emergency entrances and exits form two work flow paths. The computer room of the network control center is the most important area of ​​the entire building. To ensure the safety of the flow of people in the entire machine room, hierarchical management should be carried out according to job functions, and the security of the flow of people should be resolved from time to time. In the power supply and distribution system, all the host equipment in the equipment room are equipped with special strong and weak current DS-4 copper jump sockets for the equipment room, which are installed on the anti-static floor, avoiding the installation of power supply and weak current interfaces in the equipment room under the anti-static floor The disadvantages of inconvenient use. The construction of the network center computer room directly affects the teaching quality of colleges and universities, the effect of capital investment and the future management security of the computer room. Construct an economically reasonable, safe and beautiful network control center computer room to meet the needs of the digital campus hardware platform. Source: Silicon Valley Power
