Three core applications of Shenyang Metro by Lenovo Server

A few days ago, with Lenovo Wan Quan Server R520, R525, R630 as the core of the system platform, successfully deployed in Shenyang Subway information system, for the Shenyang Metro core database systems, ticketing and accounting systems, monitoring management system, including the three core applications, built high-performance, high reliability, easy to manage the IT infrastructure platform. Shenyang Subway construction project is one of the important projects in the development of urban rail transit system in recent years. Since the establishment of the project in 1998, the construction of Shenyang Subway project is the most investment and the largest key project in the history of Shenyang city construction, and it is also a popular project which attracts the attention of all circles of society.　　Through the construction of subway project, we can promote the economic development of Shenyang, promoting the prosperity of cities and social progress.　　Shenyang Subway panoramic planning 11 lines, horizontal longitudinal through most parts of Shenyang, the current subway line Line 1 has begun to open a trial run, Line 2 lines are under construction, the end of 2009 civil engineering completed more than 60%. With the continuous improvement of subway construction, as an important part of urban rail transit-information construction, the status is particularly prominent.　　In accordance with the requirements of planning, to realize the requirements of security, fast and efficient, the core equipment of carrying information system has put forward the strict requirements of reliability, usability, manageability, scalability and many other aspects.　　Shenyang Metro project, according to the application can be divided into: Core database system, ticketing and accounting system, monitoring and management system three categories, according to the structure can be divided into: Central system, Site system. According to the design requirements of Shenyang Metro, the core database system involves little data in the early stage, but it should have a strong ability to expand, with the development of the business, can continuously achieve the goal of expansion and upgrade. At the same time also have a strong remote management capabilities. Ticketing and accounting system data requirements are not high, but for equipment performance has higher requirements.　　Monitoring management system data security and equipment reliability have certain requirements, and have good heat dissipation space. According to the design requirements, in the accounting center Lenovo as the core database selected Lenovo R630g7 as a carrier, to complete the overall ticketing system database management analysis, and the largest support for the 4-way CPU expansion, 256G memory expansion, in the expansion of requirements to fully meet the needs of users, configured the eye advanced version To achieve the goal of remote management. Each branch site ticketing and accounting system using Lenovo R525, configure X5450 CPU to meet high-performance application needs. command center and Site monitoring using r350g6x,5u height to bring good heat dissipation space, even if users use more than a block of external card, will not cause failure due to heat dissipation; 3 SAS hard drives with 128M independent RAID card, both improve data processing performance and provide security Redundant power supply design is the full embodiment of reliability.　　All server products Support Ioat Network acceleration technology, so that data transmission performance has greatly improved. In energy saving, Lenovo server unique Lecot Energy optimization technology, through the detection of key components working conditions, real-time adjustment systemPower consumption, in the power consumption to achieve on-demand supply, saving unnecessary power consumption, so that can effectively reduce the cost of operation and maintenance of users.　　And the five-heavy hard disk protection technology, automatic boot fault diagnosis technology "been Inside" for the system's reliability and ease of maintenance provides a strong support. In the rigorous testing in the early stage, the fitting user design needs equipment selection, so that the Lenovo server in the application System compatibility test, special external equipment and card testing in the performance of outstanding characteristics. In the field application, Lenovo server products give full play to high-performance, high reliability, high scalability and high management of the characteristics of Shenyang subway information application has injected surging momentum of development.
