Dynamically Adjusting Storage Resources In A Vast Storage Network

Abstract:

A method begins by determining storage performance for a set of storage resources of the storage network, where data is error encoded into pluralities of sets of encoded data slices in accordance with error encoding parameters, and, for a set of encoded data slices, the error encoding parameters include a decode threshold number and a pillar width threshold number. The method continues by determining a storage provisioning implementation for the set of storage resources based on the storage performance and a storage performance range threshold. The method continues by facilitating the storage provisioning implementation to produce an updated set of storage resources. The method continues by maintaining storage of the set of encoded data slices in accordance with the storage provisioning implementation, where the decode threshold number of encoded data slices of the set of encoded data slices remains available during the facilitating the storage provisioning implementation.
