随着电力信息化工作的推进,企业新业务需求的不断涌现,信息设备的数量高速增长,企业IT基础架构变得日益复杂。针对这种情况,研究x86服务器集群、数据仓库一体机与小型机这三种企业级信息系统IT基础架构在海量数据环境下的处理性能,基于不同IT基础架构设备对联机分析处理系统( OLAP)场景与联机事务处理系统( OLTP)场景进行测试。大量业务应用系统测试的结果表明,x86服务器集群可以满足企业关键业务系统的性能要求,可以替代小型机与数据仓库一体机。具有成本低、扩展能力强、灵活度高等优势的x86服务器,将被更多地部署在数据中心处理重量级的工作。使用x86服务器集群架构可以很好地提升公司在IT建设过程中的技术能力,主动掌握未来IT技术发展方向。%With the proceeding of informatization for electric power,the constant emergency of business requirements for enterprise,and the growing of devices for application systems,enterprise-class IT architecture has become increasingly complex. In view of this,the per-formance of three kinds of IT infrastructures including x86 server cluster,data warehouse integrated machine and minicomputer have been researched in the massive data environment. Three kinds of IT infrastructure devices have been experimented in OLAP and OLTP scenari-os. The test results show that x86 server clusters can meet the performance requirements for core business system. It can replace minicom-puters and data warehouse integrated machine. X86 servers,with advantages of low cost,strong expansibility and high flexibility,will be deployed in the data center to deal with more heavyweight work. The use of x86 cluster servers can greatly promote the technology in IT construction for enterprise,and actively master the future direction of IT development.
