Which isolation response should I use?

I wrote this article about split brain scenarios for the vSphere Blog. Based on this article I received some questions around which “isolation response” to use. This is not something that can be answered by a simple “recommended practice” and applied to all scenarios out there. Note that below has got everything to do with your infrastructure. Are you using IP-Based storage? Do you have a converged network? All of these impact the decision around the isolation response.

The following table however could be used to make a decision:

Likelihood that host will retain access to VM datastores Likelihood that host will retain access to VM network Recommended Isolation policy Explanation
Likely Likely Leave Powered On VM is running fine so why power it off?
Likely Unlikely Either Leave Powered On or Shutdown Choose shutdown to allow HA to restart VMs on hosts that are not isolated and hence are likely to have access to storage
Unlikely Likely Power Off Use Power Off to avoid having two instances of the same VM on the VM network
Unlikely Unlikely Leave Powered On or Power Off Leave Powered on if the VM can recover from the network/datastore outage if it is not restarted because of the isolation, and Power Off if it likely can’t.

Which isolation response should I use?” originally appeared on Yellow-Bricks.com. Follow us on Twitter and Facebook.
