{product-title} is capable of provisioning persistent volumes (PVs) using the Container Storage Interface (CSI) driver for AWS Elastic File Service (EFS).

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".

After installing the AWS EFS CSI Driver Operator, {product-title} installs the AWS EFS CSI Operator and the AWS EFS CSI driver by default in the `openshift-cluster-csi-drivers` namespace. This allows the AWS EFS CSI Driver Operator to create CSI-provisioned PVs that mount to AWS EFS assets.

* The _AWS EFS CSI Driver Operator_, after being installed, does not create a storage class by default to use to create persistent volume claims (PVCs). However, you can manually create the AWS EFS `StorageClass`.
The AWS EFS CSI Driver Operator supports dynamic volume provisioning by allowing storage volumes to be created on-demand.
This eliminates the need for cluster administrators to pre-provision storage.

* The _AWS EFS CSI driver_ enables you to create and mount AWS EFS PVs.
