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 a storage network begins by receiving, from a requestor, an access request for metadata associated with a data object, where the data object is dispersed error encoded in accordance with dispersed storage error encoding parameters to produce a set of encoded data slices and distributedly stored among a plurality of storage units, where a decode threshold number of encoded data slices are needed to recover the data object. The method continues, by generating a metadata lookup for the data object and then receiving metadata from one or more storage units associated with the storage network. The method then continues, by mapping, based on the metadata, a file path and a storage location for accessing each encoded data slice of the set of encoded data slices. Finally, the method continues by providing, to the requestor, the file path and a storage location for accessing each encoded data slice of the set of encoded data slices and facilitating retrieval of the set of encoded data slices by the requestor.

Abstract: A processing system is operable to encode data to produce a first set of data slices based on a value of a width parameter. The data is stored based on maintaining storage of the first set of data slices across a set of storage units of a storage pool. Storage of the first set of data slices is maintained in the set of storage units of the storage pool after addition of an additional set of storage units added to the storage pool. The value of the width parameter is increased to an increased value to produce an updated width parameter. The data is re-encoded in accordance with the updated width parameter to produce a second set of data slices. The data is re-stored based on maintaining storage of the second set of data slices across the expanded set of storage units of the storage pool.

Abstract: A processing system operates by: detecting an access anomaly associated with an access request from a requestor for a set of encoded data slices, the access anomaly having an unfavorable access pattern, wherein the set of encoded data slices is dispersed storage error encoded and stored in at least one storage unit of the storage network; denying the access request in response to detecting the access anomaly; generating, based on the unfavorable access pattern, an anomaly detection indicator identifying the requestor; and sending the anomaly detection indicator to other devices of the storage network.

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 includes monitoring processing of a writing process associated with a plurality of sets of encoded data slices to storage units of the storage network in accordance with error encoding parameters to produce write processing performance information, where for a set of encoded data slices of the plurality of sets of encoded data slices, the error encoding parameters include an error coding number and a decode threshold number. When the write processing performance information compares unfavorably to a desired write performance range, the method further includes adjusting at least one of the error coding number and the decode threshold number to produce adjusted error encoding parameters for writing subsequent sets of encoded data slices of the plurality of sets of encoded data slices.

Abstract: A method for execution in a storage network begins by performing a key derivation function on a password to produce a key and issuing a set of passwords based on the key to a set of storage units, where a data object is dispersed error encoded in accordance with dispersed error encoding parameters to produce a set of encoded data slices and the set of encoded data slices are stored in the set of storage units. The method continues, by receiving at least a decode threshold number of confidential information responses from the set of storage units and regenerating a set of keys for the confidential information responses. The method then continues by decrypting the confidential information responses 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 encoded data slices to produce recovered data.
