Bug Fixes History

4342748

Description: Fixed an issue where, if the summary queue size on initiators exceeds the SRQ size on the NVMe-oF target, RNR NACKs are triggered. The Congestion Control (CC) mechanism significantly reduces the rate in response to the presence of RNR, leading to a substantial drop in bandwidth during NVMe WRITE operations and mixed tests.
