摘 要
随着计算机的普及和发展,人们对有用信息的存储量越来越大,特别是网络技术
的不断发展,数据成几何形式的增长,人们对数据存储提出了更高的要求。网络存储
便成为一个非常热门的研究方向。本文剖析了目前五种主要的网络存储技术
(DAS、NAS、SAN、iSCSI和CAS),从内部机理和性能等诸多方面对其进行了分析和
比较,为有关人员选择适合自己需求的数据存储方式提供了一定的参考和帮助,并提
出在相应的网络选型时应注意的问题,和怎样选择网络存储技术。最后结合现有的网
络存储技术和存储虚拟化技术,探讨网络存储技术在GIS系统中的应用。

Abstract
With the popularization and development of computer, the storage of useful information increases
continuously, furthermore the network technology leads to the geometric growth of data, so people have put
forward higher demand for data storage. Network storage has consequently become a hot topic of research.
This paper analyzes the current five major network storage technology (DAS, NAS, SAN, iSCSI and CAS),
analyzing and comparing them from the internal mechanism and the performance and other aspects, and
provides reference and help for people to select the data storage technology suitable for themselves. The
paper also proposes the problems people should pay attention while selecting the network technology and
how to select. Finally, the paper probes the application of Internet storage technology in the GIS system ,
on the base of the existing network storage technology and storage virtualization technology.
Key words: DAS(Direct Attached Storage), NAS(Network Attached Storage), SAN(Storage
Area Network, iSCSI, CAS(Content Addressed Storage)
