5 Understanding Exalogic Networks

This chapter describes Exalogic infrastructure fabrics and associated networks.

This chapter contains the following topics:

5.1 Default Network Configuration for Oracle VM Servers

After you reimage an Exalogic compute node from Oracle Linux to Oracle VM Server, each compute node (dom0) has the following network configuration:

5.2 Network Configuration Performed by the ECU

Table 5-1 describes the networks set up by the Exalogic Configuration Utility (ECU) when it used to configure the Exalogic machine.

Note:

These are the system network partitions set by the ECU. You must not modify them.

Table 5-1 Exalogic Networks

Name of the Network Default Partition Key(X2-2, X3-2) Default Partition Key(X4-2) Device and Default IP Address Description

IPoIB-default

Default

Default

192.168.10.1/24

bond1 for compute nodes

ipmp1 for the storage appliance

Default InfiniBand partition.

IPoIB-admin

0x8001

0x0002

192.168.20.0/24

bond2 for compute nodes

ipmp2 for the storage appliance

Used for all interconnections among the different components of Exalogic Control.

IPoIB-storage

0x8002

0x0003

192.168.21.0/24

bond3 for compute nodes

ipmp3 for the storage appliance

Used internally to access shares on the storage appliance.

It is different from the IPoIB-vserver-shared-storage network.

IPoIB-virt-admin

0x8003

0x0004

bond4

172.16.0.0/16

Used by Exalogic Control for all virtualization management.

IPoIB-ovm-mgmt

0x8004

0x0005

bond5

192.168.23.0/24

Used for all Oracle VM management. This includes heartbeat, migration, and virtualization control.

IPoIB-vserver-shared-storage

0x8005

0x0006

bond6 for compute nodes, and ipmp4 for the storage appliance

172.17.0.0/16

Used to provide access to Sun ZFS Storage Appliance for customer or application vServers.

EoIB-external-mgmt

0x8006

0x0007

bond7

VLAN ID, Ethernet device/connector (Ethernet port on the Sun Network QDR InfiniBand Gateway Switch), and network IP/subnet mask defined by the user

Used to provide external access to the vServer that hosts the Enterprise Controller component of Exalogic Control.


Note:

You can change the default network configuration of IPoIB-default (192.168.10.0/24), but you cannot change its partition key.

Default Ports Assigned by ECU

For information about the default ports of the hardware components in Exalogic, see the "Default Port Assignments" section in the Oracle Exalogic Machine Owner's Guide.

For information about the default ports of Enterprise Manager Ops Center components, see the "Network Port Requirements and Protocols" section in the Oracle Enterprise Manager Ops Center Feature Reference Guide.

Table 5-2 describes the default ports assigned to the database component of Exalogic Control and to the WebLogic Server container that hosts the Oracle VM Manager component of Exalogic Control.

5.3 Network Membership of Exalogic Components

Table 5-3 outlines the network participation of the components in the Exalogic machines. The table also provides information about their InfiniBand partition membership types. N/A indicates that the component is not part of that network.
