Abstract
An apparatus comprises a host device configured to communicate over a network with a storage system. The host device comprises a multi-path input-output (MPIO) driver configured to control delivery of input-output (TO) operations to the storage system over selected ones of a plurality of paths through the network. The MPIO driver is further configured to determine mappings between ranges of logical block addresses (LBAs) of logical storage volumes and respective ones of a plurality of cache entities of the storage system, to select, for a first IO operation comprising a first set of LBAs of a first logical storage volume, a first one of the paths associated with a first one of the cache entities, and to select, for a second IO operation comprising the first set of LBAs of a second logical storage volume, a second one of the paths associated with a second one of the cache entities.
