高职院校SAN存储网络的应用研究

Research on Vocational Colleges SAN Network Storage Application

由于传统的DAS存储方式是一种直连存储方式、扩容能力有限、数据安全性低,而且每台主机的存储设备无法互通、跨主机存取时设定复杂,这种存储方式远远不能满足一些高职院校网络飞速发展的需要,基于SAN技术并结合RAID5的存储方式,有效地提高存储管理的效率,而且具有存储升级容易、数据安全性高、读写速度快、空间利用率高等。

As a result of the traditional DAS storage method is a direct way of storage, the expansion ability is limited, data security is low, and each host storage device cannot exchange, inter host access to set up a complex, especially the use of different OS of the host, some systems even cannot access; this kind of storage methods can not meet the digital library of our institute the needs of rapid development, this paper presents the use of SAN technology combined with RAID5technology to solve these problems, the practical application shows that, these two techniques can effectively improve the storage management efficiency, but also has a storage upgrade easily, high data security, reading writing speed, space utilization rate is high.
