Abstract: Methods and apparatus for storing data and metadata in a storage network. In a method, one or more processing modules of a storage network establishes a vault as a virtual memory block that maps to memory of the storage network. The method further includes receiving data for storage in the vault, selecting a first vault parameter set regarding distributed storage of the data, and encoding at least a portion of the data in accordance with the first vault parameter set to produce a set of encoded data slices. The method further includes obtaining metadata regarding the set of encoded data slices, selecting a second vault parameter set regarding distributed storage of the metadata, and encoding the metadata in accordance with the second vault parameter set to produce metadata encoded slices. The method further includes facilitating storage of the set of encoded slices and the metadata encoded slices in the vault.

Abstract: A method for execution by one or more computing devices of a storage network includes determining an encoded data slice of a set of encoded data slices needs rebuilding during an encoded data slice reduction operation. The method further includes determining whether a current number of encoded data slices of the set of encoded data slices that are not in need of rebuilding is less than a reduced rebuild threshold number associated with the encoded data slice reduction operation. When the current number is less than reduced rebuild threshold number, the method further includes rebuilding the encoded data slice.

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 execution by a computing device of a storage network includes determining an encoded data slice reduction scheme for a set of encoded data slices stored in a set of storage units of the storage network, where a data segment of data is encoded into the set of encoded data slices in accordance with encoding parameters, and where the encoding parameters include a pillar width number and a decode threshold number. The method further includes maintaining storage of the set of encoded data slices in accordance with the encoded data slice reduction scheme, where the maintaining storage includes keeping, until a deletion time for the set of encoded data slices, a number of encoded data slices of the set of encoded data slices equal to or greater than the decode threshold number and less than the pillar width number.

Abstract: A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory. The computing device obtains a data identifier associated with a data object and determines DSN address(es) associated with storage of one or more encoded data slice(s) (EDS(s)). The computing device selects slice names based on the DSN address(es) and issues at least a read threshold number of read slice requests using slice names to at least some storage units (SUs). When an insufficient number of EDSs is received, the computing device issues an alternate read slice request to an alternate SU. When a sufficient number of EDSs is received from the alternate SU and the computing device has received at least the read threshold number of EDSs, the computing device reconstructs the data segment.

Abstract: A method begins with a processing module transmitting list slice requests to distributed storage network (DSN) storage units regarding storage errors associated with a data segment. The method continues with the processing module receiving list slice response messages and depending on the list slice response messages, determining whether a first threshold priority or a second threshold priority number of error-free EDSs associated with the first data segment has been stored. The method proceeds with the processing module, depending on the number of error-free EDSs associated with the first data segment that have been stored, issuing read slice requests and rebuilding one or more EDSs associated with the data segment.

Abstract: A method for execution by a computing device includes, receiving, from a requesting device, a request for a data segment of a data object that is or is to be stored in storage units of a content delivery network. The method further includes determining whether the data segment is stored in a cache memory of the content delivery network or in the storage units. When stored in the cache memory, the method includes retrieving the cached data segment, and sending it to the requesting device. When stored in the storage units, the method includes, sending read requests regarding the data segment to the storage units, receiving, in response to the read requests, at least a decode threshold number of encoded data slices, decoding the at least the decode threshold number of encoded data slices to reproduce the data segment, and sending the data segment to the requesting device.

Abstract: A method begins with a first group of computing devices of a plurality of computing devices of a storage network receiving data objects having a first data type identifier of a plurality of data type identifiers, where the plurality of data type identifiers correspond to a plurality of data types associated with the data objects. The method continues with the first group of computing devices interpreting the data objects having the first data type identifier to sort, based on sorting criteria the data objects into a first processing category and a second processing category. The method continues with the first group of computing devices error encoding the data objects in the second processing category based on short term storage error encoding parameters to produce pluralities of sets of encoded data slices and sending the slices to storage and execution units.

Abstract: A method for processing partial tasks in a distributed storage network (DSN) includes receiving a partial task request message for a DS execution unit, where the partial task request message includes corresponding partial tasks. The method continues by processing each partial task request message in accordance with the processing parameters to produce task request slice groupings, generating slices, such that each message is directed at a corresponding DS execution unit, and the sending the slice groupings and the task request slice groupings to the selected DS execution units for storage therein. The method continues by retrieving at least a decode threshold number of task response slices of one or more task response slice groupings from the DS execution units, decoding the task response slices, retrieving at least a decode threshold number of partial result slices, and decoding the partial results slices and processing the partial results to produce a result.

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.
