7.1.3 InfiniBand Switches in the Oracle Exadata Database Machine

Oracle Exadata Database Machine includes two 36-port InfiniBand leaf switches (Sun
Datacenter QDR InfiniBand Switch 36). These two switches located in the middle of
the rack are referred to as leaf switches. A spine switch is included in unit 1 of Oracle
Exadata Database Machine Full Rack and Half Rack configurations.
Note:
In this document, the leaf switch located in the lower unit of the Oracle
Exadata Database Machine rack is referred to as leaf 1. The leaf switch
located above leaf 1 in the Oracle Exadata Database Machine rack is
referred to as leaf 2.
For more information about Oracle Exadata Database Machine's rack layout
and hardware components, see the Oracle Exadata Database Machine
Owner's Guide.

7.2 Physically Connecting the Network

This section describes the following topics:
•

Physical Layout Considerations

• Scenario 1: Single Exalytics In-Memory Machine with Oracle Exadata Database
Machine
• Scenario 2: Clustered Exalytics In-Memory Machine with Oracle Exadata

Database Machine

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.
