Abstract
Methods and systems are disclosed that relate to scheduling the processing of I/O requests in a cache for a plurality of logical devices associated with the cache. An exemplary method includes identifying a minimum target number of write destages to be performed with respect to a logical device per unit time. In identifying the minimum target number, factors such as a write pending count and an average queue length of writes pending may be considered. The method further includes enforcing the target minimum number of write destages. A disclosed method of enforcing the target includes tracking the number of write destages performed on the logical device and increasing a priority for a write request to the logical device when the minimum target number of write destages is not met.
