Hi Troy Clavell,
In vSphere 4 the Cluster node is in Primary /Secondary approach, but vSphere 5.0 onwards Mater/Slave.
I dont understand how it will work on combination of Esxi 4 and 5 host is on the same cluster.
also vSphere 5.0 we have data store heartbeat future before declare a host is isolated.
Thanks
Sundararajan.
