A method begins by a dispersed storage (DS) processing module dividing a very large data object into a plurality of data regions and generating a data object storage tracking table that includes sections for identifying one or more data regions that are available or unavailable for retrieval. The method continues with the DS processing module dividing a first data region into data segments and disperse storage error encoding the data segments to produce sets of encoded data slices. The method continues with the DS processing module sending DSN write requests regarding storing the sets of encoded data slices to storage units and when at least a write threshold number of write responses is received for each of the sets of encoded data slices, updating the data object storage tracking table to indicate that the first data region is available for retrieval.

Utilizing data object storage tracking in a dispersed storage network

A method for execution by one or more processing modules of a dispersed storage network (DSN) includes receiving a data access request for at least one data segment stored in the DSN. One of a plurality of identity units is selected, based on the data access request. The method determines, via the selected one of the plurality of identity units, whether to allow the data access request. The data access request is processed, when the data access request is allowed via the selected one of the plurality of identity units.

Dispersed storage system with identity unit selection and methods for use therewith

A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by identifying a data object to access within a DSN. The method continues by identifying a vault ID based on the data object. The method continues by obtaining an object ID based on the data object. The method continues by selecting at least one generation ID based on generation status. The method continues, for each generation ID, by generating at least one set of slice names using the vault ID, the generation ID, and the object ID. The method continues, for each set of slice names, by generating a set of slice access requests that includes the set of slice names and accessing the DSN utilizing the set of slice access requests.
