Abstract

A distributed file system integrates the storage devices on the network and stores files on remote file servers so that clients can access them through Internet anytime and anywhere. However, to ensure the reliability and security of critical data, the maintenance cost is usually high. Some researches propose solutions to use Webspace as storage. These are efficient for individual users or small enterprises. However, these solutions have three drawbacks: 1) they support only single specific Webspace, 2) they can not ensure data confidentiality, and 3) they can not ensure data reliability. This paper introduces a distributed file system, the general file system (GFS), which integrates the advantage of distributed file system and the convenience of Webspace. GFS also integrates several heterogeneous spaces and promises the reliability and security. Besides, for users, it is easy to operate GFS through the interface provided by the virtual file system. At the end, the experiments result shows that GFS outperform than other solutions using Webspace.
利用网络空间的无缝可靠的分布式网络文件系统
分布式文件系统将网络中的存储设备集成在一起,将文件存储在远程文件服务器上,使客户端可以随时随地通过Internet访问文件。但是,为了保证关键数据的可靠性和安全性,维护成本往往很高。一些研究提出了使用Webspace作为存储的解决方案。这对于个人用户或小型企业来说是有效的。然而,这些解决方案有三个缺点:1)它们只支持单个特定的web空间;2)它们不能保证数据的机密性;3)它们不能保证数据的可靠性。本文介绍了一种集分布式文件系统的优点和网络空间的便利性于一体的分布式文件系统——通用文件系统(GFS)。GFS还集成了多个异构空间,保证了可靠性和安全性。此外,对于用户来说,通过虚拟文件系统提供的接口,可以方便地操作GFS。最后,实验结果表明GFS优于其他使用Webspace的解决方案。
