Transferring data encoding functions in a distributed storage network

A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method comprises:

• receiving, by the one or more processing modules, a data access request to access a data object that is based on a set of encoded data slices (EDSs) that is distributedly stored among a plurality of storage units (SUs) associated with a plurality of storage sites, wherein a data object is segmented into a plurality of data segments, and wherein the data segment of the plurality of data segments is dispersed error encoded in accordance with dispersed error encoding parameters to produce a set of encoded data slices (EDSs);
• selecting, by the one or more processing modules, respective numbers of SUs at each of the plurality of storage sites to support the data access request;
• based on the respective numbers of SUs at each of the plurality of storage sites, selecting, by the one or more processing modules, a first computing device that is associated with a first storage site of the plurality of storage sites to process the data access request;
• and
• transmitting, by the one or more processing modules, the data access request to the first computing device to be processed by the first computing device.

A first computing device comprising:

• an interface configured to interface and communicate with a dispersed or distributed storage network (DSN);
• memory that stores operational instructions;
• and
• processing circuitry operably coupled to the interface and to the memory, wherein the processing circuitry is configured to execute the operational instructions to:
• receive a store data request, wherein the store data request includes a data object and a consistency level indicator;
• select one or more storage units (SUs) from each of a plurality of storage sites to support the store data request;
• select a second computing device associated with a storage site of the plurality of storage sites to process the store data request;
• transmit the store data request to the storage site of the plurality to storage sites;
• dispersed error encode, by the second computing device, the data object in accordance with dispersed error encoding parameters to produce a plurality of sets of encoded data slices (EDSs);
• and
• transmit, by the second computing device, one or more sets of EDSs of the plurality of sets of EDSs to a one or more storage sites of the plurality of storage sites.
