    Abstract: A method begins by a processing module concurrently receiving a first data stream and a second data stream for transmission to a receiving entity. The method continues with the processing module dividing each of the first and second data streams to produce a first plurality of data blocks corresponding to the first data stream and a second plurality of data blocks corresponding to the second data stream, where data blocks of the first plurality of data blocks are time aligned with data blocks of the second plurality of data blocks. The method continues with the processing module creating a data matrix from the first and second plurality of data blocks and generating a coded matrix from the data matrix and an encoding matrix. The method continues with the processing module outputting a plurality of pairs of coded values of the coded matrix to the receiving entity.

    Abstract: A method begins by a processing module of a storage network receiving a first plurality of pairs of coded values corresponding to first data segments of a first data stream and a second data stream. The method continues with the processing module generating a received coded matrix to include a plurality of groups of selected coded values and when the received coded matrix includes a decode threshold number of pairs of coded values, generating a data matrix from the received coded matrix and an encoding matrix. The method continues with the processing module reproducing the first data segment of the first and second data streams, while maintaining the time alignment of the first and second data streams.

    Abstract: A method begins by a processing module of a storage network analyzing storage network memory for a level of usability and based on the analyzing, selecting alternative memory available for receipt of encoded data slices stored in current memory, where a data object is segmented into a plurality of data segments and a 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. The method continues with the processing module determining whether to move encoded data slices from current memory to alternative memory and based on a determination to move slices, allocating alternative memory. Finally, the processing module moves at least some encoded data slices from a current memory to alternate memory and updates a memory assignment mechanism for the at least some encoded data slices.

    Abstract: A storage unit (SU) includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The processing circuitry is configured to execute the operational instructions to perform various operations and functions. The SU, of a first SU set, receives a partially encoded slice request to restore a set of encoded data slices (EDSs) that are based on first dispersed storage error coding function parameters. The SU generates a decode threshold number of partially EDSs based on the first and second dispersed storage error coding function parameters. The SU then outputs the decode threshold number of partially EDSs to a second SU set to undergo selective combination respectively to generate new EDSs for storage within the SUs of the second decode threshold number of SUs of the second SU set.
