摘要： A processing system of a storage network operates by: sending, to at least one storage unit of the storage network, at least one read request corresponding to at least a read threshold number of a set of encoded data slices to be retrieved, wherein the set of encoded data slices correspond to data, wherein the data is coded in accordance with dispersed error coding parameters that include a write threshold number and the read threshold number, wherein the write threshold number is a number of encoded data slices in the set of encoded data slices and wherein the read threshold number is a number of the set of encoded data slices that is required to decode the data; receiving, via the at least one processing circuit and from the at least one storage unit, a first subset of the set of encoded data slices, wherein the first subset is missing at least one missing encoded data slice that was not received from the at least one storage unit in response to the at least one read request and wherein a number of encoded data slices in the first subset is less than the read threshold number; generating, via the at least one processing circuit, at least one rebuilt encoded data slice corresponding to the at least one missing encoded data slice utilizing locally decodable redundancy data, wherein the locally decodable redundancy data generated from a second subset of the set of encoded data slices that includes the at least one missing encoded data slice; and recovering, via the at least one processing circuit, the data based on the at least one rebuilt encoded data slice and the first subset.

摘要： A method for execution by one or more computing devices of a storage network includes generating an audit record data file regarding the execution of a data access request associated with a transaction within the storage network, where the transaction is associated with encoded data slices. The method continues with generating an audit object data log that includes at least the audit record data file and storing the audit object data log in at least one memory of the storage network. The method continues retrieving, from the at least one memory, the audit record data file of the audit object data log based on the information associated with the transaction. The method continues auditing the transaction for storage network operational compliance based on at least the audit record data file.

摘要： A method for execution by one or more computing devices includes selecting a first routing path from a plurality of routing paths to a set of storage units based on routing path performance information, where the first routing path has a performance level greater than a first performance threshold. The method further includes selecting a second routing path from the plurality of routing paths based on the routing path performance information, where the second routing path has a performance level less than or equal to the first performance threshold. The method further includes sending a first subset of encoded data slices to the set of storage units via the first routing path for storage therein. The method further includes sending a second subset of encoded data slices to the set of storage units via the second routing path for storage therein.

摘要： A method for execution by a computing device of a storage network includes appending at least a decode threshold number of encoded key slices of a set of encoded key slices to at least some encrypted data segments of a plurality of encrypted data segments to produce secure packages. The method further includes error encoding, in accordance with error encoding parameters, the secure packages to produce sets of encoded data slices, where a first secure package of the secure packages is dispersed storage error encoded using an error encoding function of the error encoding parameters to produce a first set of encoded data slices of the sets of encoded data slices. The method further includes outputting the sets of encoded data slices for storage in memory of the storage network.

摘要： 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.

摘要： A method includes receiving a data retrieval request. A plurality of identifiers are determined in accordance with the data retrieval request. Integrity information is generated based on determining the plurality of identifiers by performing a cyclic redundancy check. Stored integrity information corresponding to the data retrieval request is compared with the integrity information, where the stored integrity information was previously generated by performing the cyclic redundancy check. When the stored integrity information compares unfavorably with the integrity information, corruption associated with the plurality of identifiers is determined.

摘要： Methods and apparatus for selection of memory devices in a distributed storage network. In an embodiment, a computing device receives a data object for storage and forwards the data object to a buffer for temporary storage, the buffer comprised of a first memory devices of a first memory type. A system level storage efficiency is determined for the data object based, at least in part, on a data attribute associated with the data object. Second memory devices, of a second memory type, are selected based on the system level storage efficiency preference, and compatible dispersed storage error encoding parameters for the data object are determined. The data object is encoded using the encoding parameters to generate a plurality of encoded data slices, which are provided to the second plurality of memory devices for storage. Further, system addressing information is generated based on an identifier associated with the data object.
