摘　　要：介绍了一种可扩展性强、性能和成本可控的模块式CD镜像服务器的实现原理,解决了基于Linux的服务器专有操作系统中中文支持不好的问题。通过网络访问的方式对模块式CD镜像服务器的性能进行了评测。评测结果显示,对该服务器的数据访问速度大大高于对共享光驱中数据的访问速度。尤其是在多客户访问的情况下,该服务器可提供远远高于普通共享光驱的数据访问带宽。This paper introduces the principle of implementing a modularized CD Image server that has excellent scala-bility and controllable performance and cost efficiency.The problem of the bad compatibility to Chinese language encoun-tered in Linux operating system-based server is solved especially.By accessing the data stored in the server via net-work,the performance of the modularized CD Image server is evaluated.The experimental results show that,the through-put of reading data from the CD Image server is much higher than that from the sharing CD-ROM.This is especially true when the server is dealing with multi-client access.
