• Additional networks (optional): Each Sun Network QDR InfiniBand Gateway
Switch has eight 10 Gb Ethernet ports. The number of ports used in Exalogic
deployment depends on your specific bandwidth requirements (how many 10 Gb
ports can be shared per compute node) and on your specific LAN/VLAN
connection requirements. A group of 16 compute nodes connects 2 Sun Network
QDR InfiniBand Gateway Switches in an active-passive bond. Each compute node
is connected to two separate Sun Network QDR InfiniBand Gateway Switches for
HA.
Note that each compute node requires a bond for each external network (physical
network or VLAN).

operating system.
