IP Address Requirements for Exalogic Machine

Management Client Access Network
Network Requirements
Requirements
Minimum of 68 IP
addresses
• At least 2 IP
addresses per
management
network for
compute nodes:
1 IP address for
ILOM
1 IP address for
ETH0
• 2 IP addresses
per controller/
server heads in
the storage
appliance
• 1 IP address per
Sun Network
QDR InfiniBand
Gateway Switch
Minimum of one IP address per
Bond. Additional IP addresses
per Bond added as per Service or
Protocol requirements.
For example, HTTP may only
expose a floating IP address to an
external Load Balancer and not to
the HTTP Client (only observes
VIP of Load Balancer), while JMS
may expose the virtual IP directly
to the JMS Client.
Typically, an application server
supporting both HTTP and JMS
will have a floating IP address for
JMS (public) and a floating IP
address for HTTP (private to the
Load Balancer).
In addition, T3 typically uses a
minimum of two IP addresses.
One of these IP addresses is
private to the Load Balancer, and
the other floating IP address is
exposed to application server
clients. An application server
client initially accesses the
application server through a well-
known virtual IP address, such as
T3://floating_IP:Port. This
request is received by an external
Load Balancer, which forwards
the packet to a private IP address
of the application server. The
application server responds with
a handle that consists of another
floating IP address, such as
W_floatingIP:Port. This
request is forwarded through the
Client. For any new requests,
Client accesses the application
Server through
T3:W_floatingIP:Port.
InfiniBand Private
Network (IPoIB)
Requirements
Minimum of one
IP address per
bond per compute
node.
Exalogic machine
full rack contains
30 compute
nodes.
One compute
node can be a
member of only
one private
network of an
application
domain.
