The volume is still named storage so, to our docker registry image, nothing has changed. But underneath, instead of going a directory on the host, the NFS mount will be mounted instead and the registry will read and write there. ONTAP supports up to 1000 FlexVols per cluster node with a cluster maximum of 12,000 FlexVols. If your Docker volume requirements fit within that limitation, the ontap-nas driver is the preferred NAS solution due to the additional features offered by FlexVols such as Docker-volume-granular snapshots and cloning.
