基于Linux的附网存储服务器的实现和评测

因特网带来数字信息量的快速增长,局域网中传统的服务器由于繁多的功能已经不堪重负,网络存储技术的兴起为海量数据存储提供了解决途径。针对中小型企业的局域网,该文提出在成熟的IP网络中配置附网存储设备(NASD,Network-AttachedStorageDevice)作为企业数据集中存储的解决方案。在开发的NASD主模块中,优化的Linux操作系统和网络服务程序安装在一块固态电子盘中,和数据磁盘分开。经过初始化的配置后,管理员和用户可以在局域网中通过网页登陆NASD,进行管理和数据访问。利用Benchmark(标准检查程序)对开发的附网文件存储服务器进行了性能评测,试验结果表明服务器具有良好的数据输入输出(I/O,Input/Output)性能。

Implementation and Evaluation of a Network-Attached Storage Server Based on Linux

Along with the developments of the Internet,the size of digital information is increasing rapidly.The conventional server in a Local Area Network(LAN)cannot provide the satisfying storage service because of the multiple functions on it.Network storage offers some solutions for the mass data storage.For the LAN of small enterprises,acting as a file server,a Linux-based Network-Attached Storage Device(NASD)is developed to resolve the problem of data centralized storage.In the primary module of NASD,the optimized Linux operation system and the applications developed for network services are stored in a Disk On Module(DOM).After initialization,the administrator and users can access the NASD through the web browser.Some benchmark programs are adopted to evaluate the Input/Output (I /O)performance of the file server.
