7.2 Physically Connecting the Network
This section describes the following topics:
7.2.1 Physical Layout Considerations
It is assumed that the rack containing the Oracle Business Intelligence Machine and the Oracle Exadata Database Machine rack are placed side by side in the data center. Consider the length of the connecting InfiniBand cables when placing the racks in your data center.
You can place up to two Oracle Exalytics Machines in an Oracle Exadata Database Machine rack.
7.2.2 Scenario 1: Single Exalytics In-Memory Machine with Oracle Exadata Database Machine
Figure 7-1 shows how a single (non-clustered) Oracle Business Intelligence Machine is connected to an Oracle Exadata Database Machine rack.

Description of "Figure 7-1 Non-Clustered Oracle Exalytics In-Memory Machine Connected to Oracle Exadata Database Machine"
For high availability purposes, connect the two ports of the InfiniBand card, which is installed in the Oracle Business Intelligence Machine, to separate leaf switches of the Oracle Exadata Database Machine. For example, as shown in Figure 7-1, you can connect port 1 of the Oracle Business Intelligence Machine's InfiniBand card to the leaf 1 switch (Sun Datacenter InfiniBand Switch 36 installed in the lower unit of the Oracle Exadata Database Machine). In addition, you should connect port 2 of the Oracle Business Intelligence Machine's InfiniBand card to the leaf 2 switch (Sun Datacenter InfiniBand Switch 36 installed in the upper unit of the Oracle Exadata Database Machine). Port 1 can function as the active port, and port 2 can function as the passive port.
Note:
On the leaft switches of the Oracle Exadata Database Machine, the following free ports can be used:
Ports 5B, 6A, 6B, 7A, 7B, and 12A
7.2.3 Scenario 2: Clustered Exalytics In-Memory Machine with Oracle Exadata Database Machine
Figure 7-2 shows how a cluster of Oracle Business Intelligence Machines is connected to an Oracle Exadata Database Machine rack.

For high availability purposes, connect the active port of the InfiniBand card included in each of the Oracle Business Intelligence Machines to the leaf 1 switch (Sun Datacenter InfiniBand Switch 36 installed in the lower unit of the Oracle Exadata Database Machine). In addition, you should connect the passive port of the InfiniBand card included in each of the Oracle Business Intelligence Machines to the leaf 2 switch (Sun Datacenter InfiniBand Switch 36 installed in the upper unit of the Oracle Exadata Database Machine). Port 1 can function as the active port, and port 2 can function as the passive port.
Note:
On the leaft switches of the Oracle Exadata Database Machine, the following free ports can be used:
Ports 5B, 6A,6B,7A,7B, and 12A
