摘要
网络用户数量的激增使得单机网络服务器已经不能满足用户需求 ,而通常的多机结构又具有维护代价高 ,负载不均衡等缺陷 ,使用 Cluster结构加上可扩展软件构成的单一入口点机群系统却可以很好地解决这一问题 .介绍了在曙光 2 0 0 0 - II型大规模并行计算机上采用该结构构造而成的多节点 Web服务器和 Em ail服务器 ,并对它们的性能进行了评测 .多节点 Web服务器使用 SPEC公司开发的 Spec Web99评测 ,而 Em ail性能则用国家智能机研究开发中心构造的 Email评测软件 ,并通过对评测结果的分析 。
The rapidly increased amount of Web users makes single node Web server out of date and the traditional multi node systems have the defects of difficult maintenance and imbalance traffic. The systems with single entry point, which is made up of cluster system and scalable software, can meet these needs. The multi node Web server and email server are introduced, which are implemented in Dawning 2000 II. Their performance abilities are evaluated. SpecWeb99 is used as evaluating tools for the performance of Web server, the email performance evaluating system is constructed by NCIC (national center for intelligent computing systems) and their results show the excellent scalability of this architecture.
