Storage unit solicitation for encoded data slice storage

Abstract:

A method includes obtaining, by a computing device of a storage network, data for storage and interpreting metadata associated with the data to determine data storage requirements. The method further includes selecting a plurality of storage units of the storage network as target storage units based on the data storage requirements and a storage sequence and transmitting a solicitation message to the target storage units. The method further includes receiving favorable responses from at least some of target storage units, selecting storage units from the at least some of the target storage units to produce a set of selected storage units, determining an error coding dispersal storage function, encoding a data segment of the data in accordance with the error coding dispersal storage function to produce a plurality of encoded data slices, and outputting the plurality of encoded data slices to the set of selected storage units for storage therein.
