高校数字图书馆海量信息存储系统架构研究

高校数字图书馆改变了传统图书馆的存在和服务方式，结合校园网络平台，实现用户对图书馆文献检索和数据共享网络化和图书馆办公自动化。本文结合主流的海量信息存储技术DAS （直接附加存储）、NAS （网络附加存储）、SAN （存储区域网络）和云存储，设计数据资源分级分布存储的高校数字图书馆网络信息存储系统架构。满足了数字图书馆存储系统的高容量、易扩容和数据资源安全可靠性等方面需求。

Research on Mass Information Storage System Architecture of University Digital Library

The existence and service mode of traditional library has been changed in the university digital library,combin-ing with the campus network platform, retrieval and sharing of library literatures for users＇ network, and simplification is realized;and the library office automation is realized. In this paper,combining with the mainstream mass information storage technology that includes DAS （direct attached storage）, NAS （network attached storage）, SAN （storage area network） and cloud storage, the university digital library network information storage system architecture is designed, that the data resources are hierarchical distributed storage. This architecture meets the digital library storage system＇s re-quirements of high capacity,easy expansion and data resources safety.
