Hi,
I am trying to understand how does someone know whether there is enough resources for HA capability. I know that HA can fail if there is no memory and CPU resources but just wondering how is this calculated or how you can see whether you have or don't have HA capability in a cluster.
I was looking at resource allocation in HA cluster but doesnt say too much.
\So my question would be how would you determine that you have enough resources for HA to do its job. Certainly I dont want to end up with the situation that I dont have enough capacity to perfor HA.
