In this multirack configuration scenario, all connections with both racks will remain as they are when delivered to the site. No connections will be moved or removed to make the cross connections. In addition, a spine switch in either rack is not required.
All cross-connections between the Exalogic machine quarter rack and the Exadata Database Machine quarter rack are made using the four Infiniband switch ports 1[a,b] and 2[a,b]. Table 6-7 describes the connections between the leaf switches of the two racks being connected.

Note:
R2 in Table 6-7 indicates an Exadata Database Machine full rack that is being connected to an Exalogic machine full rack (R1).
In Table 6-7, ports 1A and 1B are horizontal connections across the two machine racks being connected (top leaf switch to top leaf switch). Ports 2A and 2B are the cross connections between the racks (top leaf switch to bottom leaf switch).
You require only 8 cables to connect an Exalogic machine quarter rack and an Exadata Database Machine. If these systems are side by side, you can use the 5-meter Infiniband cables included in the spares kit to complete these connections.
