Hi all,
Are there any performance or other impacts of sharing datastores between 2 HA clusters within the same vcenter (all vsphere5)?
For example if you separated the hosts into separate clusters due to differing network restrictions or ESXi editions (standard vs Enterprise)
Cluster1
HOST1 + HOST2
DATASTORE1 + DATASTORE2
Cluster2
HOSTA + HOSTB
DATASTORE1 + DATASTORE2
Having started reading the vsphere 5 clustering technical deepdive book I’m not sure how the master in each cluster would behave trying to take ownership of the datastores or how this would affect HA?
I see no reason why hb,poweron and protectedlist files from each cluster could not co-exist on the datastores but I guess don’t understand how the datastore ownership process works or would be affected.
Any clarification on this or other considerations would be much appreciated. Also it would be good to hear if anyone is running a similar configuration.
many thanks
