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 implementation principle of a modular CD image server with strong scalability, performance and cost control, and solves the problem of poor Chinese support in the proprietary Linux-based server operating system. The performance of the modular CD mirror server was evaluated by means of network access. Evaluation results show that the server’s data access speed is much higher than the shared optical drive data access speed. Especially in the case of multi-client access, the server can provide much higher data access bandwidth than a common shared optical drive.
