    摘要： A method for execution by a computing device of a storage network begins by receiving a write request for a data object, determining a plurality of data regions for the data object, determining storage identification information for each data region of the plurality of data regions and generating a storage table for the data object that includes information sufficient to identify each data region of the plurality of data regions. For a first data region of the plurality of data regions the method continues by dividing the first data region into a plurality of data segments, and dispersed error encoding the plurality of data segments to produce a plurality of sets of encoded data slices. The method then continues by sending a write request for each encoded data slice of each set of encoded data slices of the plurality of sets of encoded data slices to the storage network, and when at least a write threshold number of write responses is received for each of the plurality of sets of encoded data slices the method ends by updating the storage table to indicate that the first data region is available for retrieval.

    摘要： 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.
