Abstract
An apparatus includes at least one processing device configured to establish a plurality of paths between at least one initiator of a host device and a plurality of targets of respective storage nodes of a distributed storage system, and for each of a plurality of input-output operations generated in the host device for delivery to the distributed storage system: to access a target lookup service of the host device to determine a particular one of the storage nodes that stores data for a logical storage volume and offset targeted by the input-output operation, to select a particular one of the plurality of paths from the initiator to one of the targets on the particular storage node, and to send the input-output operation to the particular storage node over the selected path. The initiator and the targets are illustratively configured in accordance with a designated standard storage access protocol.
