== Overview

{product-title} is capable of provisioning persistent volumes (PVs) using the Container Storage Interface (CSI) driver for OpenStack Cinder.

Familiarity with xref:../../storage/understanding-persistent-storage.adoc#understanding-persistent-storage[persistent storage] and xref:../../storage/container_storage_interface/persistent-storage-csi.adoc#persistent-storage-csi[configuring CSI volumes] is recommended when working with a Container Storage Interface (CSI) Operator and driver.

To create CSI-provisioned PVs that mount to OpenStack Cinder storage assets, {product-title} installs the OpenStack Cinder CSI Driver Operator and the OpenStack Cinder CSI driver in the `openshift-cluster-csi-drivers` namespace.

* The _OpenStack Cinder CSI Driver Operator_ provides a CSI storage class that you can use to create PVCs. You can disable this default storage class if desired (see xref:../../storage/container_storage_interface/persistent-storage-csi-sc-manage.adoc#persistent-storage-csi-sc-manage[Managing the default storage class]).

* The _OpenStack Cinder CSI driver_ enables you to create and mount OpenStack Cinder PVs.

[NOTE]
====
{product-title} provides automatic migration for the Cinder in-tree volume plugin to its equivalent CSI driver. For more information, see xref:../../storage/container_storage_interface/persistent-storage-csi-migration.adoc#persistent-storage-csi-migration[CSI automatic migration].
