Abstract
A method for evolving dispersed storage network (DSN) memory in a DSN begins by a processing module 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. The method continues with the processing module, for a given state of evolution of the DSN memory, interpreting the tracking information 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, where the virtual memory vault is mapped to the set of the storage units, where 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.
