Abstract: Embodiments of the present disclosure relate to throttling processing threads of a storage device. One or more input/output (I/O) workloads of a storage device can be monitored. One or more resources consumed by each thread of each storage device component to process each operation included in a workload can be analyzed. Based on the analysis, consumption of each resource consumed by each thread can be controlled.

Abstract: In a data storage system in which a first storage array and a second storage array maintain first and second replicas of a production volume, the replicas are made discoverable and accessible while inconsistent. Each storage array maintains an invalid track list of inconsistencies. Initially, all tracks are marked as invalid. While background synchronization is eliminating inconsistencies, accesses to invalid tracks are resolved by exchanging data associated with IOs and updating the invalid track lists based on IO bias and other factors.
