> It would be useful if the HA for Hosts section of the admin guide had some explanation
of any relevant Global Settings. In particular I think the cluster.memory.allocated.capacity.disablethreshold
is relevant since it directly controls how much RAM is allocated to a cluster and effectively
how much free RAM will be available when an HA event occurs. There is similar information
in the Set and Monitor Total VM Limits per Host section, but often the memory allocation is
the limiting factor for a cluster rather than raw VM count. 
> Note that this explanation may need to be changed for 4.2 due to the introduction of
memory over-provisioning.
