RECONFIGURING DATA STORAGE IN MULTIPLE DISPERSED STORAGE NETWORKS
First Claim
1. A method comprises:
- determining access performance to copies of dispersed storage encoded data, wherein the copies of the dispersed storage encoded data are stored in a set of a plurality of dispersed storage networks (DSNs);
when the access performance is not at a desired access performance level, modifying the set of the plurality of DSNs based on the access performance and the desired access performance level to produce a modified set of the plurality of DSNs; and
for a new DSN of the modified set of the plurality of DSNs;
determining error coding dispersal storage parameters based on local data retrieval accesses allocated to the new DSN; and
facilitating the new DSN storing another copy of the dispersed storage encoded data.

Abstract
A method begins by a processing module determining access performance to copies of dispersed storage encoded data, wherein the copies of the dispersed storage encoded data are stored in a set of a plurality of dispersed storage networks (DSNs). The method continues with the processing module modifying the set of the plurality of DSNs based on the access performance and the desired access performance level to produce a modified set of the plurality of DSNs when the access performance is not at a desired access performance level. The method continues with the processing module, for a new DSN of the modified set of the plurality of DSNs, determining error coding dispersal storage parameters based on local data retrieval accesses allocated to the new DSN and facilitating the new DSN storing another copy of the dispersed storage encoded data.
