 In addition to the drivers listed in the following table, ROSA functions with CSI drivers from third-party storage vendors. Red Hat does not oversee third-party provisioners or the connected CSI drivers and the vendors fully control source code, deployment, operation, and Kubernetes compatibility. These volume provisioners are considered customer-managed and the respective vendors are responsible for providing support. See the link:https://docs.openshift.com/rosa/rosa_architecture/rosa_policy_service_definition/rosa-policy-responsibility-matrix.html#rosa-policy-responsibilities_rosa-policy-responsibility-matrix[Shared responsibilities for {product-title}] matrix for more information.
