Distributed storage network for storing a data object based on storage requirements

A method for use in a user device of a distributed storage network (DSN), the method comprises:

• determining, via a system that includes processing circuitry, to store a data object comprising a plurality of data segments;
• determining, via the system, one or more storage requirements for storing the data object in one of a plurality of DSN memories in the distributed storage network;
• determining, via the system, one or more DSN attributes associated with each of the plurality of DSN memories;
• selecting, via the system, one of the plurality of DSN memories to produce a selected DSN memory in response to a weighted comparison of the one or more storage requirements of the data object with the one or more DSN attributes for the selected DSN memory;
• selecting, via the system, one of a plurality of DSN processing units to produce a selected DSN processing unit;
• transmitting, via at least one network interface, a store request message to the selected DSN processing unit to generate a plurality of encoded data slices using an error encoding dispersal function by encoding the plurality of data segments using the error encoding dispersal function to generate a plurality of encoded data segments and interleaving each of the plurality of encoded data segments into the plurality of encoded data slices;
• and
• transmitting, via the at least one network interface, the plurality of encoded data slices to the selected DSN memory.

A non-transitory storage medium for use in a user device of a distributed storage network (DSN), that stores instructions, when executed by processing circuitry, that configure the processing circuitry to:

• determine to store a data object comprising a plurality of data segments;
• determine one or more storage requirements for storing the data object in one of a plurality of DSN memories in the distributed storage network;
• determine one or more DSN attributes associated with each of the plurality of DSN memories;
• select one of the plurality of DSN memories to produce a selected DSN memory in response to a weighted comparison of the one or more storage requirements of the data object with the one or more DSN attributes for the selected DSN memory;
• select one of a plurality of DSN processing units to produce a selected DSN processing unit;
• transmit, via at least one network interface, a store request message to the selected DSN processing unit to generate a plurality of encoded data slices using an error encoding dispersal function by encoding the plurality of data segments using the error encoding dispersal function to generate a plurality of encoded data segments and interleaving each of the plurality of encoded data segments into the plurality of encoded data slices;
• and
• transmit, via the at least one network interface, the plurality of encoded data slices to the selected DSN memory.
