摘要
信息系统作为国家电网公司日常运营的关键平台,一旦出现数据丢失、网络中断、数据服务停止等情况,所有分支机构、营业网点和业务处理活动将会中止,甚至造成终端客户数据的丢失。本设计从集约化发展要求出发,按照统一规划、同步建设的原则,建立集中式信息系统容灾中心,保障数据的安全性、业务的连续和可靠性。容灾中心的总体设计方法以功能为导向,采用了数据库和存储数据复制技术,立足数据级容灾,面向应用级容灾;从容灾中心功能分区、存储网络、数据复制等几方面进行了阐述。
Information system is the key platform to support the daily operation of State Grid Corporation of China. Any accidents of data lost, network broken or data service termination would cause the stop of service and business processing of all branches and commercial networks, and even worse it may cause the lost of customers＇ information. Following the requirements of intensive development and principles of unified planning and synchronized eonstruetion, a centralized information system disaster tolerance center is built. This center guarantees data security and business continuity and reliability. The general design of the center is function oriented, and it uses datahase and storage replication technology. It concentrates on data layer disaster tolerance, and explores to application layer and data center disaster tolerance.
