The following are the connection choices based on the number of Ethernet ports:
– 1 active 10 Gb Ethernet port shared by up to 8 compute nodes
– 2 active 10 Gb Ethernet ports shared by up to 8 compute nodes
* 1 port shared by 4 compute nodes for 1 LAN
* 1 port shared by 8 compute nodes for 2 LANs (1 port per LAN per
compute node)
– 4 active 10 Gb Ethernet ports shared by up to 8 compute nodes
* 1 port shared by 2 compute nodes for 1 LAN (1 port per LAN per
compute node)
* 1 port shared by 4 compute nodes for 2 LANs (1 port per LAN per
compute node)
* 1 port shared by 8 compute nodes for 4 LANs (1 port per LAN per
compute node)

6.4.2 IP Address Requirements
An Exalogic machine requires a large number of host names and IP addresses during
initial configuration. The number of IP addresses required for a particular network,
such as the management network, depends on the type of system. The network
configuration, such as host names and IP addresses, used during installation is
generated from information you supply to your Oracle technical representative in the
completed configuration worksheet. See Network Configuration Worksheets .
Configure the new IP addresses in your existing networks only after you have
completed the configuration worksheets, and received the installation Template from
your Oracle representative. All IP addresses in the installation Template must be
unassigned at the time of initial configuration. In addition, all IP addresses must be
statically assigned IP addresses, not dynamically assigned (DHCP) addresses.
All InfiniBand physical IP addresses in
BOND0
must be in the same subnet, with a
minimum subnet mask of 255.255.240.0 (or /20). The subnet mask chosen should be
wide enough to accommodate possible future expansion of the Exalogic machine and
InfiniBand network. Each device (compute nodes, switches, and storage appliance) in
the Exalogic rack is assigned a separate Local Identifier (LID) by the IB Subnet
Manager. Oracle Exalogic supports a single IP over IB (IPoIB) link over a logical
Exalogic deployment over the IB subnet. Multiple IP subnets can be layered on top of
the default IPoIB link.
Table 6-2 lists the IP address requirements for the Exalogic machine:
