| 摘 要： | 电力二次系统的运行可靠性和数据安全性要求日益提高,目前所采用的主机内置或外置的磁带机对数据进行单机人工冷备份方式越来越不适应需要,研究一种全方位、多层次的“数据容灾备份系统”势在必行。在分析了DAS、SAN、NAS的特点后,结合电力二次系统的特点,提出了电力二次系统存储备份建设方案,即基于DAS NAS SAN的存储备份方案设计,实现了异构环境下电力二次系统数据的自动在线备份和快速恢复,提高了电力二次系统的运行可靠性。

| Abstract: | Power services are based on lots of data storage,and these data can not be lost.With the rising of distributed network,the current data storage by one computer is unsuitable for distributed network.Perfecting "data backup system" should be popularized.After analyzing the characteristic of DAS,SAN,NAS and electrical secondary system,the paper puts forward a data backup project for Automation of Electric Network Management.The design of data storage on DAS NAS SAN for Automation of Electric Network Management realizes automatic on-line backup and restoring fast and improves the reliability and data security. |
