Your SnapDrive license can reside either on the local host or on the storage systems that you are using SnapDrive to manage.
If you choose to install SnapDrive with licensing per storage system rather than with a host-side license, you can execute SnapDrive operations only on storage systems that have a SnapDrive or SnapManager license installed. Licensing SnapDrive on the storage system requires Data ONTAP 7.2.6 or later.
