Abstract: A method for execution in a storage network begins by determining to adjust a version number associated with a data object stored in the storage network, where the data object was dispersed storage error encoded to produce a set of encoded data slices. The method continues by identifying a number of versions associated with the data object and based on the number of versions identified and the adjusted version number associated with the data object, generating metadata associated with the data object. The method then continues by issuing a write request for each encoded data slice of the set of encoded data slices to the set of storage units, where each write request includes the metadata associated with the data object.

Abstract: A method for a storage network begins by receiving, from a requestor, an access request for metadata associated with a data object, where the data object is dispersed error encoded in accordance with dispersed storage error encoding parameters to produce a set of encoded data slices and distributedly stored among a plurality of storage units, where a decode threshold number of encoded data slices are needed to recover the data object. The method continues, by generating a metadata lookup for the data object and then receiving metadata from one or more storage units associated with the storage network. The method then continues, by mapping, based on the metadata, a file path and a storage location for accessing each encoded data slice of the set of encoded data slices. Finally, the method continues by providing, to the requestor, the file path and a storage location for accessing each encoded data slice of the set of encoded data slices and facilitating retrieval of the set of encoded data slices by the requestor.

Abstract: A method for a computing device begins by generating a set of write requests regarding a set of encoded data slices and sending the set of write requests to a set of storage units, where each write request includes an encoded data slice of the set of encoded data slices and a version attribute, where a data object is dispersed error encoded in accordance with dispersed error encoding parameters to produce the set of encoded data slices. The method continues with the computing device receiving a write response indicating a version number conflict and in response to the version number conflict, retrieving a latest version of the data object, generating an updated set of write requests and sending the updated set of write requests to a set of storage units.

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 includes, for a current phase of a multiple phase write operation to write a set of encoded data slices to a set of storage units, determining whether to send a write performance threshold number of write requests to a subset of the set of storage units regarding a write performance threshold number of encoded data slices of the set of encoded data slices, where the set of encoded data slices includes a total number of encoded data slices, and wherein the write performance threshold number is less than the total number and greater than or equal to the write threshold number. When the write performance threshold number of write requests is to be sent to the subset of the set of storage units, the method continues by sending the write performance threshold number of write requests to the subset of the set of storage units.

Abstract: Methods and apparatus for efficient storage of a data object in a storage network. A method for execution by one or more processing modules of a storage network begins by receiving a store data request including a data object and a data identifier, and generating a source name for the data object. The method continues by determining whether the data object is already stored in memory of the storage network. In response to determining that the data object is already stored in the memory of the storage network, the method further includes identifying location information for the data object, storing the location information using the source name, and updating metadata for the data object to indicate that an additional copy of the data object is stored in the memory of the storage network.

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.
