基于IP的SAN存储技术研究

Study on SAN Storage Technology Based on IP

存储区域网络(SAN,即StorageAreaNetwork)是一个连接服务器和存储设备的网络,是存储区域中最流行的技术。先分析了存储体系结构中各种存储技术的特点,讨论了存储技术的经典发展;在介绍了IP存储网络协议的同时,详细阐述和分析了基于iSCSI协议的IPSAN环境;然后讨论了SAN的另一种实现方式———IPSAN与InfiniBand服务器结构的整合,最后预测了SAN存储技术的未来发展。

A network connecting servers and storage devices, Storage Area Network(SAN) is the most popular technology in the storage field. This paper analyzes the characteristics of several kinds of storage in the storage network architecture , and then discusses the classic development of the storage technology. It introduces IP storage protocol, expounds and analyzes the IP SAN environment based on iSCSI protocol, and then discusses another implementation method —— the conformity between InfiniBand server and IP SAN. Finally, it indicates the future of SAN storage technology.
