2.1.8 Enhanced RoCE Network Discovery

Oracle Exadata relies on the high-performance RoCE Network Fabric that connects all the database and storage servers. Oracle Exadata System Software release 24.1.0 introduces new capabilities that make it easier to discover and monitor the RoCE Network Fabric:

• configure_roce_hostinfo.sh scans the RoCE Network Fabric and labels each RoCE switch port, identifying the hostname, IP address, and port number of the link target. This information makes it easy to understand what each RoCE switch port is connected to and can be used to construct a map of the RoCE Network Fabric.

• rocelinkinfo scans the RoCE Network Fabric and presents real-time status information for each link. The output is presented using the same format as the output of the Linux iblinkinfo command. This utility does not depend on configure_roce_hostinfo.sh. However, the output from rocelinkinfo is more informative after all of the RoCE switch ports have been labeled by running configure_roce_hostinfo.sh.
