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. |

1. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to;
for a given period of time, determine average write throughput to a solid-state storage device over the given period of time; responsive to determining the average write throughput to the solid-state storage device over the given period of time is greater than a high throughput threshold, increment a time register; responsive to determining the average write throughput to the solid-state storage device over the given period of time is less than a low throughput threshold, decrement the time register; responsive to the time register exceeding a high throttle threshold, set throttling on write throughput to the solid-state storage device:, and responsive to the time register falling below a low throttle threshold, remove throttling on write throughput to the solid-state storage device. |
