基于iSCSI的网络数据存储技术研究

Study of Network Data Storage Technology Based on iSCSI

网络存储目前已经成为数据存储技术的大趋势,而存储区域网络(SAN)则是这种趋势的主流技术.相比FC SAN架构,iSCSI(IP SAN)架构有着更经济、更具扩展性、传输距离更远等优势.文中总结了数据备份的主要存储方式及关键技术,分析了SAN两种存储架构的优势和缺点.另外,详细介绍了基于iSCSI的IP SAN架构,并阐述了使用IP SAN架构进行网络数据传输.

Network storage has become a general trend of data storage technology,and Storage Area Network （SAN）is the mainstream technology of the tendency. To comparing with FC SAN architecture,iSCSI（IP SAN） architecture has advantages of more economical,more scalable,further transmission distance and so on. In this paper,the main storage methods and key technologies of data backup were summarized,and the advantages and disadvantages of two SAN storage architectures were analyzed. In addition,the IP SAN architecture based on iSCSI was introduced in detail,and transmitting data on network using the IP SAN architecture was elaborated.
