Abstract: A data object to be stored in one or more memories as a first set of encoded data segments is received at a storage processing module. An index to include an entry identifying the data object to be stored is updated, and storage of the data object is initiated. Initiating storage of the data object includes initiating storage of the first set of encoded data segments. A determination is made regarding whether storage of the data object to the one or more memories has been completed. If storage of the data object has been completed, the entry identifying the data object to be stored is removed from the index.

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 processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by performing a key derivation function on a password and issuing a set of blinded passwords to a set of storage units. The method continues by receiving at least a decode threshold number of confidential information responses, regenerating a set of keys using the associated passkeys of the confidential information, decrypting a set of encrypted slices of the confidential information using the set of keys to reproduce a set of encoded data slices, and dispersed storage error decoding a decode threshold number of the set of reproduced encoded data slices to produce recovered data.

Abstract: A distributed storage network (DSN) stores sets of encoded data slices in sets of storage units. A first storage unit assigned to store an encoded data slice included in a set of encoded data slices transmits a rebuild request associated with the storage error to a second storage unit. The second storage unit generates the rebuilt encoded data slice in response to the rebuild request, and transmits the rebuilt encoded data slice back to the first storage unit, which stores the rebuilt encoded data slice.

Abstract: A method for updating software of storage units of a set of storage units in a storage network. In an embodiment, each storage unit of the set of storage units determines a data slice storage status for data slices stored in the storage unit (e.g., by monitoring rebuilding messages relating to the data slices). A processing module of the storage network obtains the data slice storage status of the storage units of the set of storage units and determines whether to perform a software update to software of the storage units of the set of storage units. Determining whether to perform the software update includes determining, based on the data slice storage status of the storage units, whether a threshold number of storage units are associated with a favorable data slice storage status. In response to determining that a threshold number of storage units are associated with a favorable data slice storage status, the processing module indicates to perform the software update.

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 a processing module operably coupled to the interface and memory such that the processing module, when operable within the computing device based on the operational instructions, is configured to perform various operations. For example, the computing device generates a prioritized request that includes at least one of a task for execution or a priority level based on information stored within a storage unit (SU) of a plurality of storage units (SUs) implemented within the DSN. Note that the information corresponds to a data object that is related to a set of encoded data slices (EDSs) that are distributedly stored within the DSN. The computing device then transmits the prioritized request to the SU and receives, from the SU, a response to the prioritized request.

Abstract: A method for utilizing a decentralized agreement protocol for data access operations in a dispersed storage network (DSN) including a legacy storage unit pool and one or more non-legacy storage unit pools. In response to obtaining a DSN address associated with a data access request, a DSN computing device(s) generates ranked scoring information for the legacy storage unit pool and the non-legacy storage unit pool, the ranked scoring information based at least in part on the DSN address, a first location weight associated with the legacy storage unit pool, and a second location weight associated with the non-legacy storage unit pool. In an embodiment, the first location weight decreases over time (e.g., as a generation of legacy storage units is retired). Based on the ranked scoring information, at least one of the legacy storage unit pool or the non-legacy storage unit pool is selected for processing the data access request.
