Abstract
A system is configured to prioritize streaming disk I/O over non-streaming disk I/O by providing high priority queuing to streaming disk I/O and/or to throttle non-streaming disk I/O when the total disk I/O (streaming+non-streaming) exceeds a threshold amount for a given time quantum. When disk throttling is utilized, streaming disk I/O is processed in a first time quantum. Non-streaming disk I/O is processed, as much as possible, in the remainder of the first time quantum. Other non-streaming disk I/O remaining to be processed is deferred to a subsequent time quantum.
