Abstract: A computing device includes an interface configured to interface and communicate with a storage network, 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. A computing device receives a data access request for an encoded data slice associated with a data object, determines whether the encoded data slice is stored in the first memory and in response to a determination that the encoded data slice is not stored in the first memory, issues another data access request for the encoded data slice to a second memory, where the first memory includes access characteristics that are faster than the second memory. When a data access response including the encoded data slice is received from the second memory, a response including the encoded data slice is transmitted.

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. The computing device is operable to receive a memory access request for a data object stored within the DSN, determine a realm for the memory access request, determine an authorization service for the realm and generate an authorization request for the memory access request. The computing device is further operable to transmit the authorization request to an authorization service, receive an authorization request response from the authorization service, determine whether the memory access request is authorized and process the memory access request.

Abstract: Methods and apparatus for proxying data access requests in a storage network are disclosed. In various embodiments, a computing device associated with a first storage location of the storage network performs a method that includes receiving a portion of data that is in the process of being replicated from a second storage location of the storage network. The computing device facilitates storage of the portion of data in the first storage location of the storage network. In response to receiving a read request for the portion of data during the data replication process, the computing device determines whether the portion of data is available from memory of the first storage location. In response to determining that the portion of data is available from memory of the first storage location, the computing device issues a read response that includes the portion of data.

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.

Abstract: Methods and apparatus for identifying multiple resources of a storage network for data retrieval are disclosed. In various embodiments, a determination is made to retrieve an encoded data slice from the storage network. Based on configuration information for the storage network, one or more configurations are identified, including a current configuration. For the identified configurations, ranked scoring information relating to the encoded data slice is determined for a plurality of resources associated with the identified configurations. Based on the ranked scoring information, a resource is selected for each of the identified configurations. In addition, a retrieval likelihood level for the data slice is determined for each of the selected resources. Based on the likelihood levels for the selected resources, one or more of the selected resources are identified for encoded data slice retrieval and read slice requests are issued to the one or more selected resources.

Abstract: A method for managing memory in a storage network begins by monitoring a service life indicator for a plurality of solid-state memory devices in the storage network and determining whether a memory device of the plurality of solid-state memory devices is approaching an end-of-life event, where end-of-life event is based on a predetermined service life. When the memory device is approaching an end-of-life event the method continues by determining whether to migrate one or more encoded data slices from the memory device to an alternative memory device and based on a decision to migrate the one or more encoded data slices, selecting a migration scheme from a plurality of migration schemes for migrating the one or more encoded data slices. Finally, the method continues by facilitating migrating the one or more encoded data slices according to the selected migration scheme.

Abstract: Methods and apparatus for redirecting data access requests in a storage network are disclosed. In an embodiment, a computing device associated with the storage network performs a method that includes identifying a (second) storage pool of the storage network to replace a first storage pool of the storage network. The method includes issuing a migration message to at least one of the first storage pool or the second storage pool. The migration message initiates a replication of data from the first storage pool to the second storage pool. The method further includes receiving a write data request for the first storage pool prior to completion of the replication of the data, and forwarding the write data request to the second storage pool for further processing.
