One of the features that is introduced in vSAN 8.0 U1 for ESA is Auto-Policy Management. I personally love this feature, as it will help a lot of customers make the right decision in terms of what the default policy should be on their vSAN Datastore. Now, Pete Koehler wrote a very extensive blog post, and I don’t want to copy his work and simply rewrite it, so I suggest you read his blog for the full details on this brand new feature.
I do realize that some of you are just as lazy as I am, so here’s a short summary of what Auto-Policy Management is. Auto-Policy Management, when enabled, creates a new vSAN VM storage policy based on the capabilities enabled on your cluster and the size of your cluster. After creating the policy, the policy is also assigned to the datastore as the “default policy” so that any VMs which are provisioned without the selection of a policy get this optimized policy assigned. What influences the policy characteristics? Well: size of the cluster, stretched vs normal, host rebuild reserve enabled/disabled. All those factors will determine what kind of policy is created and associated with the datastore. If over time your cluster configuration changes, well then Skyline Health will inform you that changes are required to have an optimal policy again. Wonder what that looks like? Watch the demo below!
