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 pluralities of sets of encoded data slices to storage and execution units for storage therein.

Abstract: In various examples, a computing device of a dispersed storage network (DSN) receives a store data request including a data object. The computing device identifies a storage unit pool associated with the store data request. The storage unit pool includes a plurality of storage sets, each of the storage sets associated with a plurality of address ranges that are associated with a respective set of memories of the storage set. The computing device identifies a first set of memories of a first storage set of the storage unit pool, and issues a set of write slice requests to the first set of memories to initiate storage of encoded data slices produced from the data object. When an unfavorable storage condition is detected, the computing device identifies a second set of memories of the first storage set and facilitates storage of the data object in the second set of memories.

Abstract: A method includes encoding a data segment into a set of encoded data slices using erasure coding; storing, in storage units of a storage network, the set of encoded data slices, in accordance with a shared key-based encryption system (SKBES) having keys shared with the storage units; retrieving, at a periodic rate and in accordance with the SKBES, the set of encoded data slices from the storage units of the storage unit to verify whether individual slices of the set of encoded data slices have been corrupted. When one of the set of encoded data slices stored in one of the storage units has been corrupted, rebuilding the one of the set of encoded data slices by: retrieving the decode threshold number of other slices of the set of encoded data slices, in accordance with the SKBES; reconstructing the one of the set of encoded data slices based on the erasure encoding, to generate a reconstructed data slice; and storing, in accordance with the SKBES, the reconstructed data slice in the one of the storage units.
