基于混合云的高校图书馆存储方案研究

Research on Storage Solution of University Libraries Based on Hybrid Cloud

随着高校图书馆数字化建设的推进,产生了大量宝贵的数字资源。高校图书馆正面临越来越大的存储压力,现有的DAS、NAS和SAN三大类存储技术各有缺点,渐渐不能很好地满足高校图书馆日益增长的存储需求。高校数字资源根据性质可分为四大类,各类具有不同的存储需求。基于混合云的存储方案,可以针对不同类的资源,采用不同的存储策略,在存储访问速度、动态拓展容量、安全备份、异地容灾等方面都能很好地满足现在高校图书馆的存储需求。

With the digital library process forward, a lot of valuable digital resources are accumulated. The pressure to store those resources is increasing for the college library. The current three major storage technologies are DAS, NAS and SAN. They all have disadvantages and are not good enough to meet the increasing university library storage requirements. According to nature of digital resources, they can be divided into four categories, and each has its own storage requirements. For different storage requirements, the corresponding storage strategies are used in the storage solution based on hybrid cloud. This solution can meet the storage needs of academic libraries on storage access speed, the dynamic expansion of capacity, safety backup, and remote disaster recovery.
