Thank you for the response. No, it does not answer my questions, but you have provided some insight into this issue. I do not have a HA widget. Perhaps vSphere Client 5.1 for Windows does not have this feature. I do see this: Based on this, and the lack of the alarm, we can assume that if I brought down one of the hosts in this 2-host cluster, all the VMs would be able to start on the single remaining host, correct? And the alarm I refer to in this thread's title will only get triggered when that 98% goes to 50% or below, correct? I am still concerned about that resource distribution chart for Memory, though. It looks like I could push it up to 100% on both hosts, and still not push memory failover capacity lower than 50%. I presume this is due to the fact that my VMs don't have reserved memory, so vSphere only counts the minimal amount of memory required to start the VM, and it will depend on swapping and ballooning if all the VMs actually start using all their memory. So the alarm I'm looking for is one that replicates the resource distribution chart, and alerts when the total unutilized memory in the cluster is less than the total memory of a single host. Make sense?
