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 receiving a data access requests with regards to a data object. The method continues by identifying a vault set based on the data access request, where a plurality of storage vaults includes the vault set. The method continues by obtaining configuration information associated with the vault set and determining whether to process the data access request based on the obtained configuration information associated with the vault set.

Claims

identifying a vault set based on the data access request, where a plurality of storage vaults includes the vault set;

obtaining configuration information associated with the vault set, wherein the configuration information includes synchronization parameters for frequency of synchronization checks and a maximum allowable duration for a synchronization cycle;

determining whether to process the data access request based on the obtained configuration information associated with the vault set; and

processing the data access request in accordance with the obtained configuration information associated with the vault set.

2. The method of claim 1, wherein the receiving includes one or more of:

identifying a requesting entity, identifying a data access request type, or identifying the data object.

3. The method of claim 1, wherein the identifying includes utilizing one or more of:

a requesting entity identifier, a data access type, a data identifier, accessing at least one of a DSN directory, a system registry information, or a dispersed hierarchical index to extract an identifier of the vault set.

4. The method of claim 1, wherein the obtaining configuration information includes retrieving the configuration information from a local memory based on the identifying of the vault set or recovering the configuration information from at least one storage vault of the plurality of storage vaults.

5. The method of claim 1, wherein the determining whether to process the data access request based on the obtained configuration information associated with the vault set includes performing an authentication of the data access request utilizing the configuration information to produce an authorization request.
