 * *vSphere CSI Driver Operator*: The Operator provides a storage class, called `thin-csi`, that you can use to create persistent volumes claims (PVCs). The vSphere CSI Driver Operator supports dynamic volume provisioning by allowing storage volumes to be created on-demand, eliminating the need for cluster administrators to pre-provision storage. 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]).

+[NOTE]
+====
+Adding bare-metal nodes to an {product-title} cluster on vSphere is not supported. If you add bare-metal nodes, the cluster is degraded.

+If you still want to add bare-metal nodess, you must remove the vSphere CSI Driver. For information about how to remove the driver and the consequences of doing this, see Section _Consequences of disabling and enabling storage on vSphere_.
