摘　　要：虚拟化技术日益成为关注的焦点,正在最大程度地改变企业 IT 基础设施的部署及运营。甘肃电力协同办公系统打破原有本部、各地市公司两级部署模式,采用大集中部署服务器的技术架构构建电力业务应用系统。 2 台 IBM p6 570 小型机采用逻辑分区技术(LPAR),将单台服务器划分成多个逻辑服务器,彼此运行独立的应用程序。逻辑分区技术在甘肃电力协同办公系统中的应用,不仅可以减少服务器的数量,通过降低空间、散热以及电力消耗等途径提供一种服务器整合的方法,节省成本投资;而且可以提高可用性,带来具有透明负载均衡、动态迁移、故障自动隔离、系统自动重构的高可靠服务器应用环境。Virtualization technology increasingly becomes the focus of attention, and is changing the deployment and operation of enterprise IT infrastructure at the maximum. The collaborative office system of Gansu Electric Power Corporation breaks the original two-level deployment model with headquarter level and city level, and builds electrical business application systems on the basis of centralized server deployment architecture. Logical parti tioning （LPAR） technology is applied to two IBM p6 570 minicomputers with a single server divided into multiple logical servers and each running separate application programs. The application of LPAR technology in the collaborative office system in Gansu Electric Power Corporation, not only reduces the number of servers by means of integration and saves costs by reducing space requirement, heat dissipation and power consumption, but also improves the usability. A server application environment of high-reliability with features of transparent load balance, dynam- ic migration, automatic fault isolation, and system automatic reconstruction is established.
