Description of "Figure C-2 Exalogic Quarter Rack Network Connectivity"

In Figure C-2, NM2-GW represents a Sun Network QDR InfiniBand Gateway Switch (leaf switches). Servers refers to compute nodes in the Exalogic machine. Half of the compute nodes are connected with their active ports to the first gateway switch and their passive ports to the second gateway switch. The remaining half of the compute nodes are connected with their active ports to the second gateway switch and their passive ports to the first gateway switch. This connection is for high availability and load distribution purposes.

Exalogic machine quarter racks do not contain the Sun Datacenter InfiniBand Switch 36.
