摘要： 分析了以往分布式文件服务器的不足，提出了一种以J2EE技术为核心的基于Web的跨平台分布式多线程文件服务器的设计方案。该分布式文件服务器由一个集中控制单元和多个本地文件服务器组成。集中控制单元以数据库的方式对文件逻辑信息进行集中式管理；文件的物理信息则由位于Web不同节点上的本地文件服务器分布式地管理。本地文件服务器支持多线程文件操作和Windows、Unix、Linux等多种操作系统的文件系统。

Abstract: This paper analyzes the disadvantage of the old distributed file servers and presents a solution to a Web-based trans-platform distributed multiple-thread file server on the platform of J2EE. The distributed file server consists of one central control unit and multiple local file servers. The central control unit manages the logic information of the files as a whole on the basis of database. The local file servers, located in the different nodes of the Web, manage the physical data of the files in a distributed way. The local file server supports multiple-thread file operation, and furthermore , it supports different file systems such as: Windows,Unix and Linux.
