Host device with multi-path layer implementing efficient load balancing for active-active configuration

摘要

An apparatus comprises a host device that includes a multi-path input-output (MPIO) driver configured to control delivery of input-output (IO) operations from the host device to first and second storage systems over selected paths through a network. The MPIO driver is further configured to obtain a copy command associated with at least one of the IO operations, to identify a plurality of paths shared between source and destination logical storage devices of the copy command, to select a particular path from the identified paths, and to send the copy command to one of the first and second storage systems over the selected path. The first and second storage systems in some embodiments are arranged in an active-active configuration relative to one another. A given one of the source and destination logical storage devices may comprise a paired logical device established in accordance with the active-active configuration of the first and second storage systems.
