 If creating a cluster results in an error that `No registered resource provider found for location '<location>' and API version '2019-04-30' for type 'openShiftManagedClusters'. The supported api-versions are '2018-09-30-preview'.`, then you were part of the preview and now need to [purchase Azure virtual machine reserved instances](https://aka.ms/openshift/buy) to use the generally available product. A reservation reduces your spend by pre-paying for fully managed Azure services.

+## Exceeding Azure storage limits
+
+If requests are being throttled due to Azure storage limits being exceeded, it might be due to one of the following reasons:
+
+- There's a maximum of approximately 50 clusters per subscription ID + region. Create fewer than 50 clusters per subscription + region. For example: 25 clusters in subscription + eastus and 25 clusters in subscription + eastus2.
+- Avoid creating multiple clusters within a single subscription + region at the same time. If you need to create multiple clusters in a short period of time, federate over multiple subscriptions or regions.
+
+If the issue persists please create a support ticket for investigation.
