8.3 Physical Connectivity
On both GW switches of Oracle Big Data Appliance, four ports are available for external connections-5A, 5B, 6A, 6B. Oracle recommends that you use ports 5A on both leaf switches. If these ports are not available, use any other available port on the leaf switches.
Note:
Never connect a host (HCA) system to the spine switch inside a rack.
If the Oracle Big Data Appliance rack is connected to other Oracle Engineered Systems, port 5-6[A|B] may not be available. In such a case, it is recommended to use any other available port on the InfiniBand leaf switch of the Oracle Big Data Appliance rack. If no free ports are available, contact Oracle Support.
Figure 8-1 shows how to connect an Exalytics to a standalone BDA rack.
