Abstract

See full text

A method begins by a first computing device of a dispersed storage network (DSN) of a plurality of DSNs receiving a data segment for storage, encoding the data segment using a dispersed storage error encoding function to produce a set of encoded data slices, where each DSN of the plurality of DSNs utilizes the dispersed storage error encoding function, and generating a set of DSN addresses for the set of encoded data slices using a deterministic function. The method continues with a set of storage units of the DSN storing the set of encoded data slices using the set of DSN addresses. The method continues with storage units of the set of storage units and of another set of storage units of another DSN coordinating to store copies of encoded data slices of the set of encoded data slices in corresponding storage units of both sets of storage units.
