Enabling Throttling on Average Write Throughput for Solid State Storage Devices

摘要

A mechanism is provided for enabling throttling on average write throughput instead of peak write throughput for solid-state storage devices. The mechanism assures an average write throughput within a range but allows excursions of high throughput with periods of low throughput offsetting against those of heavy usage. The mechanism periodically determines average throughput and determines whether average throughput exceeds a high throughput threshold for a certain amount of time without being offset by periods of low throughput.
