1. A method for evolving dispersed storage network (DSN) memory in a DSN, the method is executable by a processing module and comprises: as the DSN memory evolves, generating tracking information by tracking: evolutionary change of storage units of the DSN memory; performance and reliability requirements of the DSN memory; and memory utilization of the DSN memory; and for a given state of evolution of the DSN memory: interpreting the tracking information for the given state of evolution to produce given state DSN memory data; and establishing virtual DSN address boundaries for a set of the storage units for storing data objects in a virtual memory vault of the DSN based on the given state DSN memory data, wherein the virtual memory vault is mapped to the set of the storage units, wherein the data objects are dispersed storage error encoded into pluralities of sets of encoded data slices that are stored in the set of the storage units in accordance with the virtual DSN address boundaries.
