Benefits of technology
The present invention relates to a system for dispersed storage of data and the verification of the integrity of encoded data. The technical effects of the invention include improved performance and reliability of data storage systems by ensuring effective servicing of needs at an acceptable level, as well as the ability to create pluralities of sets of slices and adding storage pools to the system. The invention also provides means to verify the integrity of encoded data and perform error decoding of data.
Problems solved by technology
However, there are times when, for example, based on a significant number of operations requested to be performed, the resources provisioned in the data storage system are incapable to be services at an acceptable level of performance.
The prior art does not provide adequate means to ensure that the needs of such a data storage system are effectively serviced at an acceptable level of performance.

Embodiment Construction
[0029]FIG. 1 is a schematic block diagram of an embodiment of a dispersed, or distributed, storage network (DSN) 10 that includes a plurality of computing devices 12-16, a managing unit 18, an integrity processing unit 20, and a DSN memory 22. The components of the DSN 10 are coupled to a network 24, which may include one or more wireless and / or wire lined communication systems; one or more non-public intranet systems and / or public internet systems; and / or one or more local area networks (LAN) and / or wide area networks (WAN).
[0030]The DSN memory 22 includes a plurality of storage units 36 that may be located at geographically different sites (e.g., one in Chicago, one in Milwaukee, etc.), at a common site, or a combination thereof. For example, if the DSN memory 22 includes eight storage units 36, each storage unit is located at a different site. As another example, if the DSN memory 22 includes eight storage units 36, all eight storage units are located at the same site. As yet ano...

A computing device includes an interface configured to interface and communicate with a dispersed or distributed 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 including to DSN traffic and storage usage among storage units (SUs) that distributedly store encoded data slices (EDSs) associated with a data object based on a Decentralized, or Distributed, Agreement Protocol (DAP) system configuration. For some instances of the DSN traffic, the computing device configures and deploys additional computing device(s) to service EDS data access operations. For some instances of the storage usage among the SUs, the computing device configures and deploys additional SU(s) to store distributedly the set of EDSs and updates the DAP system configuration.
