Abstract: A computing device of a storage network, the computing device including memory, an interface, and at least one processing module operably coupled to the memory and the interface, where the at least one processing module is operable to error encode a data segment in accordance with error encoding parameters to produce a set of encoded data slices. The at least one processing module also sends via the interface, a first subset of encoded data slices of the set of encoded data slices via a first routing path of a plurality of routing paths to a set of storage units, where the first routing path has a performance level greater than a first performance threshold, and sends, via the interface, a second subset of encoded data slices of the set of encoded data slices via a second routing path of the plurality of routing paths to the set of storage units.

Abstract: A processing system of a storage network operates by receiving a write request associated with a data object; identifying dispersed storage error encoding parameters; and determining a number of available storage units. When the number of available storage units is determined to exceed a first number, the processing system operates by: determining a first write threshold number in accordance with the dispersed storage error encoding parameters; dispersed error encoding the data object to produce a first write threshold number of encoded data slices; and writing, to available storage units, the first write threshold number of encoded data slices. When the number of available storage units is determined to not exceed the first number, the processing system operates by: determining a second write threshold number in accordance with the dispersed storage error encoding parameters associated, wherein the second write threshold number is less than the first write threshold number; dispersed error encoding the data object to produce a second write threshold number of encoded data slices; and writing, to the available storage units, the second write threshold number of encoded data slices.

Abstract: A method for a storage network computing device includes receiving a request to store a data object and generating a plurality of write slice requests, where the plurality of write slice requests includes a set of encoded data slices to be stored in the storage network and at least a decode threshold number of encoded data slices of the set of encoded data slices is required to recover a corresponding portion of a data object. The method continues by identifying a set of storage devices (from a plurality) for storage of the set of encoded data slices, where the plurality of storage devices includes one or more first memory devices local to the computing device and one or more second memory devices that are remote from the computing device. The method then continues, by storing the set of encoded data slices in the identified set of storage devices, generating a set of write slice responses relating to the set of encoded data slices and outputting the set of write slice responses.

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: 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.

Abstract: 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.

Abstract: A method for execution by one or more computing devices of a storage network includes error encoding data into a set of encoded data slices. The method further includes storing the set of encoded data slices in first storage units of a first vault in accordance with first error encoding parameters. The method further includes initiating storage of the set of encoded data slices in second storage units of a second vault in accordance with second error encoding parameters. When a decode threshold number of encoded data slices of the set of encoded data slices are stored in the second vault, the method further includes deleting one or more encoded data slices of the set of encoded data slices stored in the first vault.
