Abstract: A method for execution by one or more computing devices of a storage network, the method includes de-selecting a sequence of input encoded data slices based on de-selection information to produce deselected encoded data slices of a set of encoded data slices, where the input encoded data slices include a set of encoded data slices interspersed with a set of auxiliary data slices. The method further includes error decoding at least a decode threshold number of encoded data slices of the deselected encoded data slices in accordance with error decoding parameters to reproduce a data segment. The method further includes outputting the data segment to a requesting computing device of the storage network.

Abstract: A data segment is encrypted to produce an encrypted data segment, and a data tag associated with the data segment is generated. The encrypted data segment is encoded to generate a set of encoded data slices. At least a read-threshold number of encoded data slices are required to reconstruct the encrypted data segment. A set of write slice requests, which includes the set of encoded data slices and the data tag, is transmitted to a DSN memory. A determination is made, based on the data tag, whether a first encoded data slice of the set of encoded data slices is a duplicate of a second encoded data slice already stored within the DSN memory. If it is a duplicate, rather of storing the first encoded data slice, a reference to a location of the second encoded data slice is stored.

Abstract: Methods and apparatus for preference based selection of storage network memory for data storage. In an example, a computing device receives a data object for storage in memory of the storage network and determines a system level storage efficiency preference associated with the data object. The computing device selects a set of storage nodes of a plurality of sets of storage nodes for storage of the data object based, at least in part, on the system level storage efficiency preference. The computing device further determines dispersed storage error encoding parameters for the data object, encodes the data object in accordance with the dispersed storage error encoding parameters to produce encoded data slices, and generates system addressing information for the encoded data slices.

Abstract: A method for execution in a storage network includes receiving a request pertaining to a data object, where the request is related to a specified contiguous data range within the data object and the data object is dispersed error encoded to produce a plurality of groups of encoded data slices. The method continues by converting the request into a plurality of partial requests, where each partial request of the plurality of partial requests includes at least one partial task and transmitting each partial request of the plurality of partial requests to a storage unit of a set of storage units. The method then continues by determining when a partial request response has been received for each partial request of the plurality of partial requests and when a partial request response has been received for each partial request of the plurality of partial requests, transmitting an indication that the request pertaining to the data object has been successfully executed.

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.
