  • Patent number: 10606479
    Abstract: A method begins by obtaining dispersed storage network (DSN) operational issue information concerning a DSN memory issue in a first locally operated DSN memory of a plurality of locally operated DSN memories. The method continues with determining whether the DSN memory issue is regarding a local DSN issue or a global DSN issue. When the DSN memory issue is the global DSN issue, the method continues with determining a corrective action in response to the DSN memory issue and determining whether the global DSN management unit is configured for automatic correction of the DSN memory issue. When the global DSN management unit is configured for automatic correction of the DSN memory issue in the first locally operated DSN memory of the plurality of locally operated DSN memories, the method continues with executing the corrective action in the first locally operated DSN memory.

  • Patent number: 10585748
    Abstract: A method begins by a computing device of a dispersed storage network (DSN) maintaining a queue of pending requests to access the DSN while new requests are added to the queue and executed requests are deleted from the queue. The method continues by the computing device determining, for each pending request in the queue, a prioritization score to produce a plurality of prioritization scores. The prioritization score is determined by determining an identity of a requestor associated with a pending request, obtaining a trust score based on the requestor's identity, and obtaining a compliance score based on the requestor's identity. The trust score indicates the requestor's level of legitimate use of the DSN and the compliance score indicates the requestor's level of compliance with DSN system requests. The method continues by the computing device executing pending requests of the queue in accordance with the plurality of prioritization scores.

  • Publication number: 20200050369
    Abstract: A method begins by determining, by a local management unit of a first locally operated dispersed storage network (DSN) memory of a DSN, a DSN memory issue, where the DSN includes a plurality of locally operated DSN memories and at least one global DSN management unit, and where the plurality of locally operated DSN memories includes the first locally operated DSN memory. The method continues by determining whether the DSN issue is a global DSN issue or a local DSN issue. When the DSN issue is the global DSN issue, the method continues by determining whether the local management unit is configured as a DSN global management unit. When the local management unit is not configured as the global DSN management unit, the method continues by generating DSN operational issue information based on the DSN memory issue and sending the DSN operational issue information to the global DSN management unit.

  • Patent number: 10545699
    Abstract: A method for execution by a computing device within a dispersed storage network (DSN). The method beings when data accesses occur for a data object of a storage container within the DSN. The method continues by updating, for at least some of the data accesses, an object value for the data object to produce an updated object value. The method continues by updating an object retention cost for the data object to produce an updated object retention cost. The method continues by updating a data object retention policy for the data object based on the updated object value and the updated object retentions costs. When one of the data accesses is a deletion event, the method continues by utilizing a current updated data object retention policy to determine a deletion-retention option for the data object. The method continues by executing the deletion-retention option on the data object.

  • Publication number: 20190394272
    Abstract: A computing device includes an interface configured to interface and communicate with a communication system, a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory that is configured to execute the operational instructions to perform various operations. The computing device monitors a current state of a distributed storage and task processing network (DSTN) management unit by periodically collecting metadata that is compared to a previously recognized similar state. The computing device facilitates returning a resolution to the DSTN management unit to modify the current state using corrective actions and the DSTN management unit is configured to automatically execute the resolution or to record the resolution. Recorded resolutions are later passed to operators assigned to the DSN.

  • Patent number: 10505915
    Abstract: A method for execution by a computing device of a dispersed storage network (DSN) begins by receiving a data segment for dispersed storage error encoding. Prior to encoding, the method continues by determining whether to compress the data segment by predicting a first estimated processing cost (EPC) based on EPCs to dispersed storage error decode a compressed set of encoded data slices to recover a compressed data segment and EPCs to decompress the compressed data segment to recover the data segment and by predicting a second EPC based on EPCs to dispersed storage error decode the set of encoded data slices to recover the data segment. When the first EPC compares favorably to the second EPC, the method continues by compressing the data segment to produce the compressed data segment and dispersed storage error encoding the compressed data segment to produce the compressed set of encoded data slices.
