摘　　要：针对数字图书馆对网络存储新的需求,分析传统的DAS,NAS和先进的SAN互联网络存储技术,比较三者的技术差别。运用系统可靠性理论分析SAN架构的冗余技术及其主要的性能指标体系,论证SAN的多链路并行交换技术的优越性。以此为基础,提出并设计SAN架构"双塔型"网络存储解决方案,并根据中南大学数字图书馆资源建设情况,将此方案投入实际上线运行。经过2年运行结果表明,所设计的SAN架构"双塔型"网络存储解决方案与传统的DAS和NAS比较,突破了响应速度、系统安全和系统容量三大瓶颈。To satisfy the new demands of network-storage in digital library, the interconnection technology of Network-Storage for traditional DAS, NAS and advanced SAN, and the differences between them were analyzed and compared. The redundant technology of the SAN construction and its main performance index system were analyzed based on system reliable theory, and the superiority of the multi-links parallel exchange technology for SAN was given. According to above works, a ＂twin-tower＂ type of network-storage on SAN was designed and realized in the library of Central South University. The runs for 2 years show that the frame has the advantages of response speed, system safety and capacity over traditional DAS and NAS.
