Abstract: A storage network operates by: identifying a set of data objects having a common trait from a plurality of data objects for storage via the storage network; combining the set of data objects to produce a concatenated data object; encoding the concatenated data object in accordance with a dispersed encoding function to produce a set of encoded data blocks; and generating a mapping of the set of data objects to the set of encoded data blocks, wherein the mapping facilitates retrieval from the storage network of individual data objects of the set of data objects.

Abstract: A method includes receiving, by a storage unit of a storage network, a check request message from a computing device of the storage network, where the check request message includes a group of slice names of a plurality of sets of slice names associated with a plurality of sets of encoded data slices, where a plurality of data segments are dispersed storage error encoded into the plurality of sets of encoded data slices. The method further includes determining, by the storage unit, whether an error condition exists for an encoded data slice associated with the group of slice names. When no, the method includes sending, by the storage unit, a check response message to the computing device, where the check response message includes a group of slice information regarding the group of slice names. When yes, the method includes disregarding sending the check response message.

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 distributed storage integrity system in a dispersed storage network includes a scanning agent and a control unit. The scanning agent identifies an encoded data slice that requires rebuilding, wherein the encoded data slice is one of a plurality of encoded data slices generated from a data segment using an error encoding dispersal function. The control unit retrieves at least a number T of encoded data slices needed to reconstruct the data segment based on the error encoding dispersal function. The control unit is operable to reconstruct the data segment from at least the number T of the encoded data slices and generate a rebuilt encoded data slice from the reconstructed data segment. The scanning agent is located in a storage unit and the control unit is located in the storage unit or in a storage integrity processing unit, a dispersed storage processing unit or a dispersed storage managing unit.
