Abstract
A host device is configured to communicate over a network with a storage system comprising a plurality of storage devices. The host device comprises a multi-path input-output (MPIO) driver configured to control delivery of input-output (IO) operations from the host device to ports of the storage system over selected ones of a plurality of paths through the network. The MPIO driver of the host device is further configured, for each of at least a subset of the ports, to obtain from the storage system information characterizing a current number of host devices connected to the port and a current available capacity measure of the port, and to limit an amount of the IO operations that are delivered over one or more of the paths to the port based at least in part on the obtained information.
