 The included CSI (openebs in local-hostpath mode) is a great start for storage but soon you might find you need more features like replicated block storage, or to connect to a NFS/SMB/iSCSI server. If you need any of those features be sure to check out the projects like [rook-ceph](https://github.com/rook/rook), [longhorn](https://github.com/longhorn/longhorn), [openebs](https://github.com/openebs/openebs), [democratic-csi](https://github.com/democratic-csi/democratic-csi), [csi-driver-nfs](https://github.com/kubernetes-csi/csi-driver-nfs),
