Abstract

See full text

A method begins by a processing module of a dispersed storage network (DSN) determining that a set of storage units of the DSN will be substantially used for read operations of dispersed storage error encoded data. For the set of storage units, the method continues with the processing module determining an actual level of reliability in retrieving a decode threshold number of encoded data slices per read request of a plurality of read requests. The method continues with the processing module comparing the actual reliability to a desired level of reliability in retrieving the decode threshold number of encoded data slices per read request of the plurality of read requests. When the actual reliability exceeds the desired reliability by a reconfiguration threshold, the method continues with the processing module removing one or more storage units from the set of storage units.
