摘要
某些双机热备服务器由于投运时间较长或者设备老化,当其中某台机停运导致另一台关键服务器单机运行时,系统功能失效的风险非常高。提出了一种为系统关键服务器配置冷备机的方案,从而形成冷-热备混合配置的系统。数据表明,该方案可减少每次停机过程中系统的单机运行时间且能有效降低风险,保证调度自动化系统的安全稳定运行。
In some dual-server hot standby system,due to that the system operated for too long time or the equipments are aged,when one server of the two servers is stopped,the other key server has to operate individually,and the risk of system function failure is increased greatly.A new scheme was proposed,in which a cold standby server is configured for the key server of the system,and a cold-hot mixed standby system is formed.Data show that the scheme can shorten the server alone operation time during a server failure,the risk can be reduced effectively,and the dispatching automation system can operate more safely and stably.
