Site-based coordination of distributed storage network memory

A computing device of a group of computing devices of a dispersed storage network (DSN), the computing device comprises:

• an interface;
• a local memory;
• and
• a processing module operably coupled to the interface and the local memory, wherein the processing module functions to:
• create a plurality of DSN storage sites via a DSN management unit;
• configure each of the plurality of DSN storage sites, via the DSN management unit, to include a subset of a plurality of DSN storage units;
• retrieve a current site configuration for the subset of a plurality of DSN storage units;
• elect a local master management unit for each of the DSN storage sites, wherein the local master management unit maintains aggregated views of each of the DSN storage sites;
• collect, via the local master management units, local state information from each of the subset of a plurality of DSN storage units per a respective DSN storage site;
• calculate, via the local master management unit and using the collected local state information, tabulated state information for the respective DSN storage site;
• update the DSN management unit with the tabulated state information;
• and
• distribute, via the local master management unit, the tabulated state information across all nodes within the respective DSN storage site.

A dispersed storage network (DSN) including a plurality of DSN storage sites comprises:

• a DSN managing unit to manage the plurality of DSN storage sites, wherein the DSN stores data using dispersed storage error encoding;
• a local master managing unit for each of the plurality of DSN storage sites, wherein the local master managing unit is elected from a plurality of local managing units associated with a plurality of DSN storage units representing a subset of storage units of the DSN, wherein the local master managing unit includes:
• an interface;
• a local memory;
• and
• a processing module operably coupled to the interface and the local memory, wherein the processing module functions to:
• collect local state information from each storage unit of the subset of storage units of the DSN;
• and
• calculate, using the collected local state information, tabulated state information of each of the DSN storage sites;
• and
• return, via network communications, the tabulated state information to the DSN managing unit.
