配置HA vs不勾选启用HA

一旦我们在部署新虚拟机时用光了空间，为什么我们需要取消选择启用HA(它必须在限制内设置或允许控制必须限制部署超过阈值)，在那里虚拟机将在其他主机上重新启动(这将影响生产)

Hello @Godaba<\/user-mention>\u00a0this happens in high memory-usage clusters. The HA has memory reservations that prevents the cluster from powering on the VMs. The HA needs to be de-selected so that the VM can power on using available memory resources. The HA needs to be immediately selected\/enabled after powering on the VMs to protect these VMs from node failures. The possibility of the VMs being impacted is directly proportional to the time taken to disable HA, power on the desired VMs followed by enabling HA back.<\/p>","className":"post__content__best_answer"}">

Once we run out of the space while deploying new VM, why we need to Deselect Enable HA (it must be set within the limitations or Admissioin Control must restrict to deploy beyone the threshold), where the VM's going to reboot on other hosts (which will be a production impact)

你好 @Godaba这发生在内存使用率高的集群中。HA设置内存预留，导致集群无法上电虚拟机。该任务指导管理员去勾选HA，以便虚拟机在内存可用的情况下上电。必备事项虚拟机上电后需要立即选择/开启HA功能，以防止虚拟机节点故障。受影响的虚拟机的可能性与关闭HA、上电所需的虚拟机，然后重新启用HA所花费的时间成正比。
