Abstract: A method includes writing sets of encoded data slices to storage units of a storage network in accordance with error encoding parameters, where for a set of encoded data slices, the error encoding parameters include an error coding number and a decode threshold number, the error coding number indicates a number of encoded data slices that results when a data segment is encoded using an error encoding function and the decode threshold number indicates a minimum number needed to recover the data segment. The method further includes monitoring processing of the writing the sets of encoded data slices to produce write processing performance information. When the write processing performance information compares unfavorably to a desired write performance range, the method further includes adjusting at least one of the error coding number and the decode threshold number to produce adjusted error encoding parameters for writing subsequent encoded data slices.

Abstract: A method includes determining an encoded data slice of a first subset of encoded data slices associated with a set of encoded data slices requires rebuilding, where the first subset of encoded data slices is stored in a set of storage units and includes at least a decode threshold number of encoded data slices. The method further includes identifying a second encoded data slice of a second subset of encoded data slices of the set of encoded data slices, where the second subset of encoded data slices is not currently stored in the set of storage units. The method further includes generating the second encoded data slice from the first subset of encoded data slices and sending the second encoded data slice to the set of storage units, where when stored, the second encoded data slice no longer included in the second subset of encoded data slices.

Abstract: A method includes identifying an independent data object of a plurality of independent data objects for retrieval from dispersed storage network (DSN) memory. The method further includes determining a mapping of the plurality of independent data objects into a data matrix, wherein the mapping is in accordance with the dispersed storage error encoding function. The method further includes identifying, based on the mapping, an encoded data slice of the set of encoded data slices corresponding to the independent data object. The method further includes sending a retrieval request to a storage unit of the DSN memory regarding the encoded data slice. When the encoded data slice is received, the method further includes decoding the encoding data slice in accordance with the dispersed storage error encoding function and the mapping to reproduce the independent data object.

Abstract: A method for execution by a computing device to adjust efficiency of storing data in a storage network includes processing a data segment based on a storage approach to produce a processed data segment, the storage approach being based on an estimated overwrite frequency for the data segment. The method continues by error encoding the processed data segment to produce a set of encoded data slices, where a decode threshold number of encoded data slices is needed to recover the processed data segment. The method continues by storing the set of encoded data slices in the memory of the storage network.

Abstract: A method for execution by one or more processing modules of one or more computing devices begins by encoding data using a dispersed storage error encoding function to produce a plurality of sets of encoded data slices arranged into a plurality of chunksets of encoded data slices. The method continues by selecting a set of storage units for storing the plurality of chunksets and assigning a distributed computing task to each storage unit of the set of storage units. The method then continues by generating a unique key set for each storage unit of the storage units, encrypting each chunkset of encoded data slices with a corresponding one of the unique key sets to produce a plurality of encrypted chunksets and sending an encrypted chunkset of the plurality of encrypted chunksets and an indication of a corresponding distributed computing task to each storage unit of the set of storage units for storage of the encrypted chunksets and execution of the distributed computing task.

Abstract: A method includes error encoding data to produce a plurality of data slices. Metadata is determined for a data slice of the plurality of data slices. The metadata is stored in a metadata storage tree. The data slice is stored in a slice storage location indicated by the metadata. Based on determining to access the data slice, the metadata for the data slice is accessed in the metadata storage tree to determine the slice storage location for the data slice, and the data slice is accessed in the slice storage location based on determining the slice storage location for the data slice via accessing the metadata storage tree.
