Founded in 1929, Chongqing University is a national key university directly under the Ministry of Education. It is the first high-level university under the national “211 Project†and “985 Projectâ€. It has four campuses, A, B, C and Huxi. The environment is elegant, showing a profound foundation, and enjoys the reputation of “Jialing and the Yangtze River meet each other and Chongqing, the humanities and sciences are mutually beneficialâ€. At present, Chongqing University has won more than 1,000 national, provincial and ministerial (technical) awards, nearly 50 national teaching achievement awards, and more than 190 provincial teaching achievement awards.
Chongqing University is committed to making full use of advanced information and communication technologies such as Internet of Things, cloud computing, big data, mobile internet, and deep integration of information space and physical space. Based on the results of the “digital campus†construction, it is an ideal "Smart Campus", which makes talent training more humane, school governance more scientific and intelligent, campus services more mobile and perceptual, use information construction to drive school education reform and rapid development, and comprehensively improve the quality of personnel training .
The overall goal of the "smart campus" construction of Chongqing University is to complete the educational informationization target task proposed by the "Education Informationization Decade Development Plan (2011-2020)" by 2020, and form a "construction with Chongqing University". The strategic development goal of the world's high-level research-oriented comprehensive university is to adapt to the four “deep integrationâ€, that is, the deep integration of information technology and talent cultivation, and the deep integration of information technology and academic research. The deep integration of information technology and school governance, as well as the deep integration of information technology and public services.
Based on the construction needs and goals of Chongqing University's “Smart Campusâ€, Huawei provided three solutions, namely, agile campus, data center dual-active and modular computer room solutions, which will add to the building of Chongqing University's smart campus infrastructure. .
In view of the current network status of Chongqing University, Huawei provides a high-bandwidth, high-reliability, easy-to-manage and easy-to-manage agile campus network solution. The program's innovative master 1+N backup guarantees the reliability of the campus network and the high-quality new ICT service experience. It also ensures the smooth development of online teaching, mobile education and high-definition video services in schools; Integration of user authentication and policy control.
As we all know, the reliability of the core layer is the top priority of the normal operation of the campus network. Huawei's agile switch S12700's unique CSS2 switching network hardware cluster technology, innovative master 1+N backup, as long as one main control board of any frame is running normally, multi-chassis services can run stably, and the reliability of the cluster system Get a higher level of protection; also provide the industry's lowest 4μs cross-frame delay to ensure smoother flow across frames.
In the construction of the dual-active data center, Huawei uses a virtualized gateway OceanStor VIS6600T to connect to the existing user storage devices to achieve heterogeneous takeover, and through the newly-launched OceanStor S5600T array and a set of virtualized gateways OceanStor with the Huxi campus The VIS6600T builds a 4-node mirror cluster to create a dual-active data center. It implements a new OceanStor S5600T array on the Huxi campus as the main storage system, and finally unified the centralized backup of the business data for the four campuses.
Faced with the difficulty of expanding the old equipment room, poor overall coordination, and mixing of hot and cold airflow, the project uses Huawei's FusionModule2000 integrated module solution, which integrates power distribution, cooling, cabinet and other systems into the module; components and monitoring cables. Prefabrication of the factory makes the installation on site very simple and greatly reduces the online time of the business. At the same time, when the business volume grows, it can be simply copied, deployed in phases, expanded on demand, and invested in phases to improve the utilization of funds.
In the face of the old machine room, the air supply air supply has a long air supply distance, and the lower air supply causes the utilization of the cooling capacity to be low, resulting in high operating electricity costs. The project uses inter-line air conditioning and closed channels to make the cooling capacity of the precision air conditioner. The utilization rate has been greatly improved, reducing the energy consumption of the operating room. Among them, the inter-line air-conditioning arrangement and the rack arrangement are installed side by side with the server cabinet, the cold air is supplied by the cold channel, and the horizontal air supply mode is returned by the hot channel, thereby avoiding the problem of mixing the cold and hot air flow in the traditional open cooling mode. The cooling capacity of the cold aisle is evenly distributed. The lower end of the cabinet is consistent with the cooling capacity at the upper end of the cabinet. This ensures uniform temperature of the server cabinet, solves the problem of local hotspots to the greatest extent, and improves the operational reliability of the core equipment in the equipment room.
In addition, the old machine room uses power frequency UPS. The UPS equipment is bulky and takes up a lot of room space. Under low load conditions, the UPS is inefficient and consumes a lot of power, which is not in line with the energy saving and emission reduction of the new generation data center. Claim. Therefore, Huawei's modular UPS high-reliability power supply solution is adopted in this project; high-efficiency UPS achieves the highest efficiency (95%-96%) at the most common load rate (20%-40%), which is more than 10% energy saving compared with the traditional UPS. . At the same time, the low footprint of the modular UPS can save valuable space for the equipment room. Compared with the traditional tower UPS, the modular UPS brings more possibilities for the flexible expansion of the data center.
Huawei's agile network solution is an agile campus network built by Chongqing University with high reliability, large bandwidth, easy management and easy maintenance, and no coverage. It effectively carries the teaching, research and management of the school, which increases the bandwidth of the teachers and students. Times, the wireless access bandwidth is up to 100 times higher, and the maintenance workload is reduced by more than 50%.
The dual-active data center constructed at the same time fully guarantees the reliable continuity of the business, realizes the “zero†loss of data, and the business is uninterrupted; the resources are optimally utilized, the two sites realize load balancing, and the two sets of data centers are fully and reasonably applied, and the original There are storage devices that can be used normally; centralized data backup in three places simplifies system operation and maintenance management, and management costs are reduced by 30%; equipment is old, and investment is protected from repeated waste. Moreover, Huawei's dual-active data center solution can be smoothly transitioned to a two-site, three-center solution.
The successful delivery of the modular data center will reduce the original PUE value of 2.0~2.2 to about 1.6, which greatly reduces the operating cost of the equipment room; and the overall beauty and the old machine room form a sharp contrast.
The three solutions provided by Huawei provide a solid foundation for the construction of education informationization in Chongqing University, further improving the educational informationization level of the university and laying a solid foundation for the construction of the smart campus of Chongqing University. The school gave a high evaluation of this. The relevant project leader Tang teacher said: "Huawei smart campus solution makes our school's talent training more informative and humanized, governance is more scientific and intelligent, and campus services are more mobile and Perceived, using information construction to promote the school's education reform and rapid development, and comprehensively improve the quality of personnel training."
