Patent attributes
An apparatus comprises at least one processing device. The at least one processing device is configured to detect a write pressure condition by identifying at least a first set of one or more logical storage devices having a first service level objective for which at least one performance metric has a value that exceeds a specified threshold, and responsive to the detected write pressure condition, to identify at least a second set of one or more logical storage devices, having a second service level objective that is lower than the first service level objective, and that are contributing to the detected write pressure condition. The at least one processing device is further configured, for each of the identified logical storage devices of the second set, to provide a write pressure indication to control throttling of write operations directed to that logical storage device of the second set.
