A dispersed storage network (DSN) include multiple distributed computing systems, each including a DSN memory. A global scheduling module included in a coordination unit identifies a number of the distributed computing systems included in a subset of the distributed computing systems. For each distributed computing system included in the subset, the scheduling module selects a connection time based, at least in part, on the number of distributed computing systems operating in the subset. The connection time selected for a particular distributed computing system specifies a recurring time period to be used by that system for initiating connections with the global coordination unit. The scheduling module issues, to the distributed computing systems, scheduling messages that include information specifying a connection times for particular distributed computing systems.

Coordination of connection initiation scheduling in a distributed storage network (DSN)

A dispersed storage network (DSN) include multiple distributed computing systems distributed across time zones, each including a DSN memory. A global scheduling module identifies a number of the distributed computing systems operating in each of the time zones. For each distributed computing system operating in a particular time zone, the scheduling module selects a connection time based, at least in part, on the number of distributed computing systems operating in the particular time zone. The connection time selected for a particular distributed computing system specifies a recurring time period to be used by that system for initiating connections with a global coordination unit. The global scheduling module issues, to the distributed computing systems, scheduling messages that include information specifying a connection times for particular distributed computing systems.
