  = Customizing the storage profile
  
  You can specify default parameters by editing the `StorageProfile` object for the provisioner's storage class. These default parameters only apply to the persistent volume claim (PVC) if they are not configured in the `DataVolume` object.
  
  .Prerequisites
  * Ensure that your planned configuration is supported by the storage class and its provider. Specifying an incompatible configuration in a storage profile causes volume provisioning to fail.
