The predecessor of Lanzhou University of Technology was Lanzhou Polytechnic School which was founded in 1919. At present, Lanzhou University of Technology has developed into a comprehensive university of science and engineering with relatively strong engineering strength. The school library has more than 550,000 volumes of Chinese and foreign books and periodicals, all of which have realized automatic management and provide online information retrieval and document delivery services. A computer network system covering the entire campus has been built, and an information management platform and teaching platform have been established.
The Lanzhou University of Technology Library is an institution that takes science and technology literature as the main body of the collection and mainly provides information services for teaching and scientific research in the school. Since 1999, it has gradually planned to implement digital library projects in order to provide teachers and students with better quality information services. In 2002, "five platforms" for library digital infrastructure were proposed, namely: information delivery network platform, library automation management platform, digital resource platform, massive information storage and management platform, information resource processing and release platform, and gradually built and implemented.
Application needs analysis Lanzhou University of Technology completed the first phase of the "Mass Information Storage and Management Platform" project in 2004. Prior to this, it had already equipped a relatively complete Gigabit campus network, library automation management system, library website, etc. For some virtual electronic resources, due to the high penetration rate of Internet use in schools, the gradual improvement of school teaching and scientific research, and the advantages of network resources, the utilization rate of electronic resources in libraries has increased rapidly, and a large number of digital journals have been introduced Full text, e-books, etc. are very urgent, and many documents also need to be digitally processed in order to provide services.
Therefore, the library needs a mass storage system with large capacity, high security, strong applicability, and can be gradually upgraded and expanded. Through long-term inspections, the technical staff of the library choose from the application and budget of the library and the future development perspective. The all-fiber storage system based on SAN (5T capacity) is mainly connected to the SAN network through 4 servers.
Solution The Lenovo that undertakes this project uses the SF620R2 storage system. It uses the Intel Xscale architecture 600MHz RISC processor, complete hardware XOR check. Maximum support 2GB cache. Provide 4 host ports (1Gb / 2Gb adaptive), data transfer rate up to 800MB / s, I / O transaction processing can reach 100,000 IOPS. 14 disk racks, 18G / 36G / 72G / 146G Fibre Channel hard drives can be configured, and the storage capacity of a single array cabinet is 2TB. The system supports the cascading of up to 8 array cabinets, making the expanded storage capacity reach 16.4TB. The system adopts an all-fiber and fully-redundant system design. All components support hot swapping and independent operation of redundant dual-host channels. Its internal RAID subsystems are redundant with each other and support transparent fault recovery. The random software RDAC provides redundant data transmission paths. The system uses unique HotScale technology and DCE to ensure the system's online capacity expansion, Raid level change, and online firmware upgrade. The dynamic storage management software SANtricity based on the Java graphical interface can configure, monitor and online manage multiple sets of different Lenovo SureFibre storage systems in a single location via SAN or LAN. Among them, the SANshare partition function can divide a set of SF620 into 4 ~ 64 virtual storage systems, which can be used by multiple heterogeneous servers at the same time.
The solution provides four 2GbPS host interfaces, and the IOPS reaches 100K. The front end of the solution is mainly an IA architecture server running Win2K system. Each server is installed with 1 HBA card according to the situation, for a total of 4 HBA cards. At the same time, Lenovo carefully analyzed the existing application system of the library of Lanzhou University of Technology, and integrated the storage device solution with the application system, making the SAN storage system based on Lenovo SF620R2 organically integrated with the existing system of the library. Accelerate the speed of data services.
Implementation effect The system was installed and commissioned by Lenovo in May 2004, and was immediately put into use. It has installed Wanfang Digital Resource System, Chinese Periodical Full-text Database, Scholar's House e-books and other data. The total amount is 5TB. After the system is completed It operates 24 hours a day and has been operating normally. It has also experienced two sudden power outages. The construction of the library's storage system project has been well received by readers. School teachers and students have fully experienced the effect of local mirrored data use: downloading and browsing the library's electronic resource information is very fast.
The director of the museum, Xin Wanpeng, said: "The same storage capacity of 5TB, with little investment, fully meets the needs of the library. From the application situation of more than half a year, this project has been implemented very successfully."
