Abstract: A method for execution by a computing device of a storage network includes obtaining storage performance information for a set of storage units of the storage network, where data segments are dispersed storage error encoded into pluralities of sets of encoded data slices in accordance with error encoding parameters that include a pillar width number and a decode threshold number, which is a number of encoded data slices the set of encode data slices is required to reconstruct a data segment of data segments. The method further includes determining, based on the storage performance information and the error encoding parameters, a performance threshold number for a write request to store a set of encoded data slices of the pluralities of sets of encoded data slices in the set of storage units, where the performance threshold number is greater than the decode threshold number and less than the pillar width number.

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: A method includes determining whether an encoded data slice (EDS) of an “x” number of EDSs associated with a set of EDSs requires rebuilding, where the “x” number of EDSs is stored in a set of storage units of the storage network and the encoded data slice is stored in a first storage unit of the set of storage units. When the encoded data slice requires rebuilding, the method continues by identifying one of a “z” number of EDSs to replace the encoded data slice, where the “z” number of EDSs are not currently stored in the set of storage units. The method continues by constructing the one of the “z” number of EDSs from a decode threshold number of EDSs of the “x” number of EDSs and sending the one of the “z” number of EDSs to a second storage unit of 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 execution in a storage network begins by generating a set of query requests for each data segment of a plurality of data segments that includes a corresponding set of slice identifiers of a plurality of sets of slice identifiers, where each slice identifier of the corresponding set of slice identifiers includes a pillar index based on a vault affiliated with the plurality of data segments. The method continues by transmitting the set of query requests to a set of storage units affiliated with the storage network, receiving a plurality of sets of query responses from the storage units, obtaining a data identifier for slice location identification and generating a storage record that includes the data identifier and an identity of the set of storage units. The method then continues by facilitating migration of at least some encoded data slices associated with the plurality of sets of slice identifiers when the storage record compares unfavorably to a storage record requirement.
