摘要
双机备份是提高设备可靠性的重要手段,本文首先分析了在通用的服务器架构下实现双机备份的两种方案,然后根据嵌入式系统的特点,提出了一种基于分布存储方式的嵌入式系统的双机备份设计方案,并以综合业务交换平台的设计为例介绍了该方案的具体实现。
Dual-machine backup is an important method to improve the reliability of equipment. In this article, two solutions to implement dual-machine backup under the infrastructure of conventional server are interpreted. According to the features of embedded system, a solution of dual-machine hack-up based on distributed storage is introduced. To explain the realization of the solution in detail, the integrated service switching platform is used as an example.
