Emulex provides support for Fabric Notifications on their Gen6 adapters including the LPe31xxx and LPe32xxx series as well as Gen7 adapters including the LPe35xxx and LPe36xxx series. Please refer to the Fabric Perf Impact Notification (FPIN) Simple Support Matrix within the PowerMax/VMAX All Flash/VMAX3 Features Simple Support Matrix for more information and for Dell supported configurations. Emulex HBAs that support Fabric Notifications will register for these notifications and increment counters that can be retrieved through Emulex CLIs. Congestion management by the HBA is also supported with B-Series switches and directors running Fabric OS versions that support Fabric Notifications.
Please see the Congestion Management Commands chapter of the Emulex HBA Manager Application Command Line Interface – User Guide for more information.
