An apparatus in an illustrative embodiment comprises at least one processing device that includes a processor coupled to a memory. The at least one processing device is configured to implement a centralized discovery controller for coupling to a host and to a storage system accessed by the host, with the centralized discovery controller being configured to receive from the host a congestion alert, and responsive to the received congestion alert, to send to the host and to one or more targets of the storage system corresponding congestion control messages. The congestion alert is illustratively received in the centralized discovery controller from a multi-path input-output (MPIO) driver of the host, where the MPIO driver controls delivery of IO operations from the host to the storage system over selected paths. The congestion control messages may comprise respective Asynchronous Event Notifications (AENs) associated with respective Asynchronous Event Requests (AERs).
An apparatus comprising:
A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device comprising a processor coupled to a memory, causes the at least one processing device:
