Optional Connection to Exadata

Optionally, Oracle Private Cloud Appliance can be integrated with Oracle Exadata for a high-performance combination of compute capacity and database optimization. In this configuration, database nodes are directly connected to reserved ports on the spine switches of Oracle Private Cloud Appliance. Four 100Gbit ports per spine switch are reserved and split into 4x25Gbit breakout ports, providing a maximum of 32 total cable connections. Each database node is cabled directly to both spine switches, meaning up to 16 database nodes can be connected to the appliance. It is allowed to connect database nodes from different Exadata racks. For more information, see "Exadata Integration" in the Network Infrastructure section of Hardware Overview.

To cable the Oracle Private Cloud Appliance to the Exadata rack use breakout cables, with a QSFP28 transceiver on the spine switch end and four SFP28 transceivers on the other end, to connect from ports 7 - 10 on the Oracle Private Cloud Appliance spine switches to the Exadata database servers.

Reserved Breakout Ports on Spine Switch for Exadata Connection

Figure showing that port 7 of the 100GbE ports is reserved for the Exadata uplink from each spine switch.

Once the cable connections are in place, you must configure an Exadata network, which enables traffic between the connected database nodes and a set of compute instances. Refer to Creating and Managing Exadata Networks in Hardware Administration.
