Abstract
For dynamically adjusting write pacing, a calculation module calculates an interval as a maximum threshold for a primary volume divided by a first maximum pacing level for a first importance level. The calculation module further calculates a first pacing level as a number of record sets that have not been mirrored to a secondary volume divided by the interval. The first pacing level is set to the first maximum pacing level if the first pacing level is greater than the first maximum pacing level. The calculation module also selects a first pacing delay associated with the first pacing level from a delay table. A pacing module delays writes for a first channel command word writing to the primary volume by the first pacing delay.
