How to disable Datastore Heartbeating

I have had this question multiple times now, how do I disable datastore heartbeating? Personally, I don’t know why you would ever want to do this… but as multiple people have asked I figured I would write it down. There is no “disable” button unfortunately, but there is a work-around. Below are the steps you need to take to disable datastore heartbeating.

vSphere Client:

• Right Cluster object
• Click “Edit Settings”
• Click “Datastore Heartbeating”
• Click “Select only from my preferred datastores”
• Do not select any datastores

Web Client:

• Click “Cluster object”
• Click “Manage” tab
• Click “vSphere HA”
• Click “Edit button” on the right side
• Click “Datastore Heartbeating”
• Click “Select only from my preferred datastores”
• Do not select any datastores

It is as simple as that… However, let me stress that this is not something that I would recommend doing. Only when you are troubleshooting and need it disabled for whatever reason, please make sure to enable it when you are done.
