Shared ownership of namespace ranges

A computing device of a group of computing devices of a dispersed storage network (DSN), the computing device comprises:

• an interface;
• a local memory;
• and
• a processing module operably coupled to the interface and the local memory, wherein the processing module functions to:
• determine an addressing range of a storage configuration of the DSN, wherein the addressing range includes a shared virtual DSN addressing range assigned to two or more geographically dispersed storage (DS) units, and wherein the two or more geographically dispersed storage (DS) units each include multiple memory devices, and wherein the DS units each store a pillar number T of encoded data slices;
• determine a storage performance level associated with the addressing range;
• determine whether the storage performance level compares favorably to a storage performance threshold;
• and
• when the storage performance level does not compare favorably to a storage performance threshold, determine an updated storage configuration associated with the addressing range, wherein the determine an updated storage configuration includes determining to remove or add one or more DS units from the shared virtual DSN addressing range, wherein the remove the one or more DS units from the shared virtual DSN addressing range results in less DS units servicing the shared virtual DSN addressing range and the add one or more DS units from the shared virtual DSN addressing range results in more DS units servicing the shared virtual DSN addressing range;
• and
• re-assign storage resources in accordance with the updated storage configuration.
