DYNAMIC FEEDBACK-BASED THROUGHPUT CONTROL FOR BLACK-BOX STORAGE SYSTEMS

摘要

Embodiments of the present invention relate to dynamic feedback-based throughput control for storage systems. In one embodiment, a method of and computer program product for storage throughput control are provided. A plurality of I/O requests is received at a rate controller. The plurality of I/O requests is sent from the rate controller to a storage system at a first rate. Throughput of the storage system is observed. The first rate is dynamically adjusted based on the variance between the observed throughput of the storage system and the first rate.
