Storage unit (SU) operative within non-disruptive and performant migration

Abstract:

A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and a processing module operably coupled to the interface and memory such that the processing module, when operable within the computing device based on the operational instructions, is configured to perform various operations. The computing device determines to facilitate migration of encoded data slices (EDSs) from a first storage unit (SU) pool to a second SU pool and identifies storage resources associated with the EDSs to be migrated. The computing device then generates a migration schedule for the EDSs based on performance information associated with storage resources and facilitates the migration of the plurality of EDSs based on the migration schedule using the storage resources based on an aggression factor and adapts the aggression factor as deemed necessary based on the performance information.
