Abstract

See full text

A dispersed storage network (DSN) includes at least one DSN processing unit and at least one DSN memory including multiple storage units. The DSN processing unit stores encoded data slices across the multiple storage units. The data slices allow reconstruction of source data associated using fewer than all of the data slices, while preventing reconstruction of the source data using less than a threshold number of the data slices. A received message requesting access to the DSN memory is associated with a time. based on the time associated with the message, the DSN processing unit can determine that at least one memory device included in at least one storage unit is unavailable. That storage unit is excluded from storage units chosen for use by the DSN processing unit in providing the requested access. The DSN then executes the requested access using the chosen storage units.
