18. A method comprising:
identifying at least one logical storage device that has a first service level objective and is exhibiting a deficiency in one or more performance metrics;
identifying one or more additional logical storage devices each having a second service level objective lower than the first service level objective and not exhibiting a deficiency in the one or more performance metrics;
generating at least one false-positive signal specifying the one or more additional logical storage devices as each exhibiting a deficiency in the one or more performance metrics; and
providing the at least one false-positive signal to at least one host device;
wherein the at least one host device is configured to respond to the at least one false-positive signal by throttling input-output operations for the one or more additional logical storage devices;
wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
