图书馆资源服务器集群互备和双站热备互动容灾框架

Interactive Disaster Tolerant Frame of Cluster Backup and Double Hot Standby Two Sites for Resource Server in Library

针对双机互备和双站热备容灾方式单一、资源利用率和信息安全性不能兼顾的现象,本文描绘出一种建立在双站点基础上的服务器集群互动容灾的新框架。该框架可实现本地主站点不同服务器之间的局部容灾,亦可实现分别处于异地的主、被站点之间的整站容灾,充分体现了效率和安全性的统一。

For resource utilization and information security cannot take into account by double active or double hot standby two sites,this paper gives a new framework for server cluster disaster tolerant each other based on double hot standby two sites.This framework can achieve not only local disaster tolerant among different servers in the primary site,but also remote disaster tolerant between primary site and backup site.It fully embodies the unity of efficiency and security.
