Accessing data in multiple dispersed storage networks

摘要

A method begins by a processing module identifying sets of dispersed storage (DS) units for each of a plurality of dispersed storage networks (DSNs) in a computing system network, wherein a set of the sets of DS unit stores an error coded data file. The method continues with the processing module identifying a reference entity within the computing system network. The method continues with the processing module determining first data access performance information between the reference entity and a first one of the sets of DS units and determining second data access performance information between the reference entity and a second one of the sets of DS units for each of the plurality of DSNs. The method continues with the processing module storing the first and second data access performance information for each of the plurality of DSNs to produce system data access performance information.
