Abstract
An apparatus 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 multi-path input-output driver configured to schedule input-output operations for delivery to the storage system over the network. The multi-path input-output driver is further configured to measure latencies of respective ones of a plurality of paths from the host device to the storage system, to schedule particular ones of the input-output operations for delivery to the storage system over particular ones of the paths based at least in part on the measured latencies, and to control transmission of the particular input-output operations over the particular paths in accordance with the scheduling. The scheduling additionally or alternatively takes into account other measured parameters such as measured latencies of respective ones of a plurality of storage volumes of the storage system and/or measured payload size per operation metrics for each of at least a subset of the plurality of paths.
