Abstract
A method begins with one or more processing modules of a dispersed storage network (DSN) identifying a set of encoded data slices generated from a data segment based on an error encoding dispersal function. The method continues with the one or more processing modules identifying a set of storage units (SUs) that distributedly store the set of EDSs, and determining a first plurality of performance values associated with the set of SUs, followed by the one or more processing modules receiving from the set of SUs a second plurality of performance values generated by the set of SUs. The one or more processing modules continue by comparing the first plurality of performance parameter values to first desired performance values, followed by comparing the second plurality of performance parameters values to second desired performance parameter values; and based on an unfavorable comparison of the first plurality of parameter values and the second plurality of performance parameters values to the respective desired values, identifying any SUs that are below a threshold performance, and then rectifying the SUs that are below the threshold performance.
