How is NDMP data counted in the DPX License ?

Question

Answer

For any given NetApp volume, DPX will count the largest volume backup size of each volume, from all the backups, as the volume capacity, and add all the volume capacity as the NDMP node capacity as long as the data is not expired out of the catalog.
Therefore if data is deleted from a volume and replaced with new data of the same size (e.g. LUN inside volume removed and recreated)  the data is not counted twice unless the volume name is changed.
