ABSTRACT:
The invention is for a method of mapping hierarchical volume permission to top level permissions in a layered volume graph of a virtual data storage system with hierarchy of storage volumes requiring permission at every volume level and the top level volume exposed to the hosts via intelligent switches comprising: applying volume level permissions on a volume of the volume graph and mapping condensed permission hierarchically for the entire volume graph to the top level volume from said individual volume level permission.
