Patent attributes
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 a plurality of paths through a network. The MPIO driver determines latency values for the paths to the first and second storage systems, retrieves additional information corresponding to the paths and first and second storage systems, generates a first message comprising at least portions of the latency values and additional information, and sends the first message to a multi-pathing management appliance. A second message is received from the multi-pathing management appliance, the second message being generated based on at least a portion of the first message. The MPIO driver selects one or more paths for delivery of given ones of the IO operations based at least in part on at least a portion of the second message.
