    Abstract: A method begins by a dispersed storage (DS) processing module receiving data objects from a plurality of authorized users and determining a system level storage efficiency preference for a data object. The method continues with the DS processing module selecting a set of storage nodes of an on-line media storage system based on the system level storage efficiency preference and determining dispersed storage error encoding parameters. The method continues with the DS processing module encoding the data object in accordance with the dispersed storage error encoding parameters to produce encoded data slices and generating system addressing information. The method continues with the DS processing module storing the encoded data slices in the set of storage nodes using the system addressing information and updating a user profile for the authorized user to include the system addressing information.

    Abstract: A method begins with a group of storage units of a dispersed storage network (DSN) receiving a common access request. The method continues with each storage unit of the group of storage units interpreting the access request to determine whether the storage unit is an intended recipient of the access request, where storage units of a sub-set of storage units of the group of storage units are intended recipients. The method continues with each storage unit of the sub-set of storage units determining a type of the access request and a level of the access request. When the access request is a read request, the method continues with each storage unit of the sub-set of storage units retrieving each encoded data slice having an identifier of its slice address substantially matching the a given identifier of the level to produce a retrieved set of encoded data slices.
