故障和恢复测试也应该在这里执行,以便每一层至少应该有两个服务器。
Failure and recovery tests should also be performed here so there should be at least two servers for each tier.
典型示例是灾难恢复测试,其中涉及故障转移到热备用系统、测试应用程序,然后退回到主系统。
The classic example is a disaster recovery test, which involves failing over to a warm standby system, testing the applications, and then failing back to the primary systems.
通过用ewu值定义这些资源,可以在自动或手工故障转移、高可用性操作和灾难恢复测试或实现期间消除冲突。
Designing these resources with EWU values eliminates the possibility of conflict during automated or manual fail-overs, high-availability operations, and disaster-recovery testing or implementation.
