Each StorageClass contains the fields `provisioner`, `parameters`, and `reclaimPolicy`, which are used when a {{< glossary_tooltip text="Persistent Volume" term_id="persistent-volume" >}} belonging to the class needs to be dynamically provisioned. Users can request a particular class using the name of a StorageClass object.
