StorageClass has two functions:

  1. For static PersistentVolumes (those created by cluster administrator) it groups and thus enabling fine-grained assignment in PersistentVolumeClaims definitions.
  2. For dynamic mode it creates PersistentVolume automatically with defined provisioner (e.g. EBS volume on AWS). It also assign each created PersistentVolume a storageClassName parameter.
