  • Detection and mitigation of slow drain issues using response times and storage-side latency view
    Patent number: 11467765
    Abstract: An apparatus in one embodiment comprises at least one processing device configured to control delivery of input-output (IO) operations from a host device to a storage system over selected ones of a plurality of paths through a network, and to monitor response times for particular ones of the IO operations sent from the host device to the storage system. The at least one processing device is further configured to interact with the storage system to determine network latency from a viewpoint of the storage system, and responsive to (i) at least a subset of the monitored response times being above a first threshold and (ii) the network latency from the viewpoint of the storage system being above a second threshold, to at least temporarily modify a manner in which additional ones of the IO operations are sent from the host device to the storage system.
