8.1 Hardware Requirements
Oracle Big Data Appliance has three in-built InfiniBand switches. Use the two NM2-
GW leaf switches to connect the Oracle Exalytics machine. The Oracle Exalytics
machine has one InfiniBand HCA card, but it does not include any InfiniBand switch or
any instance of InfiniBand Subnet Manager.
To connect Oracle Exalytics to Oracle Big Data Appliance, you need a pair of
InfiniBand cables depending on the length requirements at the datacenter. If the total
distance between Exalytics and Oracle Big Data Appliance leaf switch ports is less
than 10 meters, you can use copper cables. If the length is more than 10 meters, you
must use fiber optic cable for InfiniBand with appropriate transceivers.
8.2 Software Requirements
The base images of both Oracle Big Data Appliance and Oracle Exalytics include
software support for InfiniBand connectivity.
