NetApp Data ONTAP cDOT multi-SVM storage driver.
This driver requires a Data ONTAP (Cluster-mode) storage system with
installed CIFS and/or NFS licenses, as well as a FlexClone license. This
driver manages share servers, meaning it creates Data ONTAP storage virtual
machines (i.e. 'vservers') for each share network for provisioning shares.
This driver supports NFS & CIFS protocols.
