DETECTING A UTILIZATION IMBALANCE BETWEEN DISPERSED STORAGE NETWORK STORAGE UNITS

摘要

A method begins by a processing module of a dispersed storage network (DSN) obtaining utilization information regarding a plurality of storage units of the DSN, where first and second sets of storage units support a first logical storage vault. The method continues with the processing module detecting a utilization imbalance between a first storage unit of the first set of storage units and a second storage unit of the second set of storage units based on the utilization information, where the first and second storage units are not a common storage unit. The method continues with the processing module executing a data storage function regarding the first logical storage vault based on the utilization imbalance.

1. A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method comprises:
obtaining utilization information regarding a plurality of storage units of the DSN, wherein first and second sets of storage units of the plurality of storage units support a first logical storage vault, wherein the first and second sets of storage units includes a common storage unit, wherein the utilization information of a storage unit of the plurality of storage units includes a listing of logical storage vaults supported by the storage unit and storage capacity consumed for each logical storage vault listed in the listing of logical storage vaults, wherein the first logical storage vault stores a plurality of encoded data objects, and wherein an encoded data object of the plurality of encoded data objects consists of a data object being dispersed storage error encoded into a plurality of sets of encoded data slices; detecting a utilization imbalance between a first storage unit of the first set of storage units and a second storage unit of the second set of storage units based on the utilization information, wherein the first and second storage units are not the common storage unit; and executing a data storage function regarding the first logical storage vault based on the utilization imbalance.
