Storage Cluster GC Scheduling for Lower Service Disruption

The patent implements dynamic scheduling of GC operations by the scheduling unit, which determines when and which storage units perform GC based on current system state and service requirements. This dynamic control allows the system to balance GC needs with service performance, preventing spontaneous GC from degrading overall system performance while ensuring GC operations are executed when appropriate.

The scheduling unit acts as an intermediary between the storage units and the GC process. It receives GC requests, determines the appropriate storage units to perform GC, and coordinates the execution timing. This intermediary layer prevents direct spontaneous GC execution by storage units, thereby controlling resource consumption and minimizing impact on data service performance.

The scheduling unit selectively activates data collection on specific storage units based on current system conditions and service requirements, rather than allowing all storage units to perform data collection simultaneously. This partial action approach ensures sufficient data collection throughput while preventing system resource exhaustion.

The system implements periodic data collection scheduling where the scheduling unit determines intervals and timing for data collection operations on different storage units. This periodic control prevents continuous simultaneous data collection across all units, balancing throughput generation with resource conservation.
