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

Familiarity with persistent storage and configuring CSI volumes is recommended when working with a CSI Operator and driver. For more information, see "Understanding persistent storage" and "Configuring CSI volumes."

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 needed (see "Managing the default storage class").

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