Chapter 22. Storage Classes

The StorageClass resource object describes and classifies storage that can be requested, as well as provides a means for passing parameters for dynamically provisioned storage on demand. StorageClass objects can also serve as a management mechanism for controlling different levels of storage and access to the storage. Cluster administrators (users with cluster-admin privileges) or storage administrators (users with storage-admin privileges) define and create the StorageClass objects that users can request without needing any intimate knowledge about the underlying storage volume sources.

In OpenShift Online, the storage class is configured and a single option is available to the user based on the underlying cloud provider.
