Abstract
An apparatus in one embodiment comprises a host device configured to communicate over a network with a storage system comprising a plurality of storage devices. The host device comprises a set of input-output queues and a multi-path input-output driver configured to select input-output operations from the set of input-output queues for delivery to the storage system over the network. The multi-path input-output driver is further configured to determine data reduction control indicators for the input-output operations, and to provide the data reduction control indicators to the storage system in association with the input-output operations. Different data reduction control indicators are associated with different ones of the input-output operations that are generated by different processes running on the host device. The storage system adapts its performance of data reduction for the different ones of the input-output operations based at least in part on their associated data reduction control indicators.
