Abstract
A system and method for implementing a Quality of Service based upon data deduplication is provided. The method may include deduplicating data and receiving a corresponding I/O request; wherein the data includes an associated dedupe count. The method may further include performing the I/O request based upon the dedupe count. For example, where no deduplication exists as indicated by a dedupe count of zero, the I/O request may be scheduled for processing when the sum of the current clock tick and the tag ratio are less than or equal to the next clock tick. In the alternative, where deduplication exists as indicated by a dedupe count that is greater than zero, the I/O request may be scheduled for processing, when the sum of the current clock tick, a negative value of the dedupe ratio, and the tag ratio are less than or equal to the next clock tick.
