Abstract
A processing device is configured to communicate over a network with a storage system comprising a plurality of storage devices. The device comprises a multi-path input-output (MPIO) driver configured to control delivery of input-output (IO) operations from the device to the storage system over selected ones of a plurality of paths through the network. The paths are associated with respective initiator-target pairs, and each of a plurality of targets of the initiator-target pairs comprises a corresponding port of the storage system. The MPIO driver is further configured to create a plurality of IO operation threads, to use a given IO operation thread to retrieve a given IO operation from an IO queue, to attempt to perform the given IO operation on a given target of the plurality of targets, and to return the given IO operation to the IO queue upon a failure to perform the given IO operation.
