Abstract
An apparatus in an illustrative embodiment comprises at least one processing device that includes a processor coupled to a memory. The at least one processing device is configured to associate a logical storage volume with at least one path between a host and at least a given one of a plurality of storage nodes of a distributed storage system, and to associate a proxy volume with respective sets of one or more paths from the host to each of the plurality of storage nodes of the distributed storage system. The at least one processing device is further configured to obtain an input-output operation directed to the logical storage volume, and to redirect the input-output operation to the proxy volume over a selected one of the paths associated with the proxy volume. Such an arrangement can avoid one or more host-side restrictions, thereby enhancing scalability of the distributed storage system.
