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 method includes identifying an existing logical storage vault having existing dispersed storage coding properties for vault transformation, where a first set of storage units support the existing logical storage vault, and a data object of first data objects stored within the first set of storage units is stored as a first plurality of sets of encoded data slices in accordance with the existing dispersed storage coding properties. The method includes identifying a new logical storage vault having new dispersed storage coding properties, wherein storage units support the new logical storage vault. The method includes transforming the first data objects from being in accordance with the existing dispersed storage coding properties to being in accordance with the new dispersed storage coding properties to produce transformed first data objects. The method includes storing the transformed first data objects in the new logical storage vault supported by the storage units.

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: Methods and apparatus determining corrective actions in a storage network. In various examples, a method (e.g., executed by one or more processing modules) includes capturing event information relating to operations performed by the storage network. The method further includes receiving an event analysis request and filtering the event information based on the event analysis request. The method also includes identifying based on the event analysis request, one or more event record entries of the event information and generating a representation of the identified event record entries. Based on the representation of the identified event record entries, a determination is made to initiate a corrective action in the storage network. In an example, the event record entries relate to user access operations or system administrative operations initiated by a device affiliated with the storage network.

Abstract: A method for execution on a storage network begins with receipt of a data object for storage by a plurality of users and continues with a storage network processing unit determining whether the data object is associated with a replica storage node of a plurality of replica storage nodes associated with the storage network. When the data object is associated with a replica storage node, the method continues by facilitating storing the data object in each replica storage node of the plurality of replica storage nodes and receiving a plurality of access responses from at least some replica storage nodes of the plurality of replica storage nodes. The method then continues by determining whether an access response threshold number of access responses have been received and finally, in response to a determination that an access response threshold number of access responses have been received, transmitting an acknowledgement to the plurality of users.

Abstract: Methods and apparatus for asynchronous replication of data in a storage network. In an embodiment, a processing module(s) of a computing device identifies at least a first storage set and a second storage set for replicated storage of data. The processing module maintains a synchronization schedule for the first storage set and the second storage set. After initiating storage of a data object in the first storage set (e.g., using first error encoding parameters), the processing module determines, based at least in part on the synchronization schedule, to synchronize the first storage set and the second storage set. In response to determining to synchronize the first and second storage sets, the processing module determines that the second storage set requires the data object to maintain synchronization with the first storage set and facilitates storage of the data object in the second storage set (e.g., using second error encoding parameters).
