-The default behavior of DeepOps is to setup an NFS server on the first `kube_control_plane` node. This temporary NFS server is used by the `nfs-client-provisioner` which is installed as the default StorageClass of a standard DeepOps deployment.
+The default DeepOps Kubernetes storage path is the `nfs-subdir-external-provisioner` chart, backed by an NFS export on the first `kube_control_plane` node. This is a convenience default for examples, smoke tests, and small internal clusters. It is not a highly available production storage design.
 
-To use an existing nfs server server update the `k8s_nfs_server` and `k8s_nfs_export_path` variables in `config/group_vars/k8s-cluster.yml` and set the `k8s_deploy_nfs_server` to false in `config/group_vars/k8s-cluster.yml`.
