高校数字图书馆存储网络建设研究与实践

Study and Practice on the Construction of Storage Network in Digital Library

就当前高校数字图书馆海量数据存储的现状及需求而言,构建一个安全、高效的存储后台已成为数字图书馆建设中的重要任务。网络存储模式主要有DAS、NAS、SAN3种,且各具特色,但由于SAN架构具有集中管理和高性能存储的优点,在现代存储模式中脱颖而出,成为当前数字图书馆普遍采用的网络存储方式。本文通过对不同存储架构的对比分析,提出一种切实可行的基于IP-SAN架构的网络存储方案。

Aiming at the current situation and the demand of mass data storage in digital libraries,it is important to build a secured and efficient database in the construction of digital libraries.There are three main types of network storage model,namely,DAS,NAS and SAN,with their own characteristics.For SAN architecture has centralized management and high-performance storage characters,it is widely used in modern digital library network storage as a storage pattern currently.This article analysed different storage architectures,then proposed a practical storage solution based on IP SAN.It will be ensure the consistency of the data,safety and reliability.At the same time,it will achieve a centralized management and accessing of different data and will provide a safe efficient management environment of storage,and it has good expansibility.
