Abstract: A method includes obtaining input encoded data slices from memory of the storage network, where the input encoded data slices include a set of encoded data slices interspersed with a set of auxiliary data slices, where a data segment was error encoded into the set of encoded data slices, and where auxiliary data was error encoded into the set of auxiliary data slices. The method further includes obtaining de-selection information associated with the input encoded data slices and de-selecting the sequence of input encoded data slices based on the de-selection information to produce deselected encoded 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 the data segment. The method further includes outputting the data segment to a requesting computing device of the storage network.

Abstract: A method includes receiving data for storage and encoding the 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 metadata storage tree is stored via a first plurality of memory devices of a first memory type. The data slice is stored in a slice storage location in a second plurality of memory devices of a second memory type. The slice storage location is indicated by the metadata. The first memory type has a higher performance level than the second memory type based on a utilization approach.

Abstract: A storage network operates by: encoding, via a dispersed error encoding, at least one data object as a write threshold number of encoded data slices; storing the write threshold number of the encoded data slices in a set of storage units of the storage network; determining when, due to a failure of at least one of the set of storage units, less than a pillar width number of the encoded data slices of a common revision are retrievable from the set of storage units: retrieving a decode threshold number of the encoded data slices from others of the set of storage units; decoding the decode threshold number of the encoded data slices to reproduce the at least one data object; restoring availability of the pillar width number of the encoded data slices of the common revision by: rebuilding at least a subset of encoded data slices of the set of encoded data slices, based on an encoding of the at least one data object; and storing the at least a subset of encoded data slices in the storage network.

Abstract: A method includes retrieving an encoded data slice from memory of a storage network, where the encoded data slice is associated with a slice integrity value stored in the memory, and where a data segment of data is error encoded into a set of encoded data slices that includes the encoded data slice. The method further includes generating a second slice integrity value based on the retrieved encoded data slice. The method further includes determining whether the second slice integrity value compares favorably to the slice integrity value. When the second slice integrity value compares unfavorably to the slice integrity value, the method further includes facilitating rebuilding of the encoded data slice to produce a rebuilt encoded data slice. The method further includes storing the rebuilt encoded data slice in the memory.

Abstract: A method begins by a processing module of a storage unit of a storage network identifying a first storage format used to store a plurality of encoded data slices in a first memory of the storage unit and continues with the processing module determining to utilize another storage format for storage of the plurality of encoded data slices. The method then continues, with the storage unit selecting a second storage format for storage of the plurality of encoded data slices and initiating migration of the plurality of encoded data slices from the first storage format to storage using the second storage format. Finally, the method continues with updating a performance metric for at least a portion of the storage network while initiating migrating the plurality of encoded data slices.

Abstract: Apparatus for tiered storage of data in a storage network. In an example of operation, a computing device receives a data object for storage and forwards the data object for storage in a first plurality of memory devices of a first memory type. The computing device determines a system level storage efficiency for the data object based, at least in part, on a data attribute associated with the data object. The computing device further selects, based at least in part on the system level storage efficiency preference, a second plurality of memory devices comprised of a second memory type. The computing device determines error encoding parameters based on the second plurality of memory devices, retrieves the data object from the first plurality of memory devices, and encodes the data object with the error encoding parameters to generate a plurality of encoded data slices for storage in the second plurality of memory devices.
