CONGESTION AWARE MULTIPATHING BASED ON NETWORK CONGESTION NOTIFICATIONS

摘要

An apparatus comprises a host device comprising a processor coupled to memory. The host device is configured to obtain a network congestion notification from a portion of a network that is utilized by the host device for submitting IO operations to a storage system. The network congestion notification comprises an indication that the portion of the network is experiencing network congestion. The host device is further configured to identify a first path of a plurality of paths as a path that utilizes the portion of the network and to adjust a dispatch weight of the first path based at least in part on the network congestion notification. The host device is further configured to submit an IO operation to the storage system along a second path instead of the first path based at least in part on the adjusted dispatch weight of the first path.
