2.4.1.1 Bonded Network Configuration for Oracle Exadata Database Machine
Two-Socket Systems
When using a bonded network configuration for database client access on Oracle
Exadata Database Machine Two-Socket Systems, the database servers are
configured as follows:
•
Port NET0: Provides access to the operating system using the management
network through the ETH0 interface.
•
Port NET1: Provides access to the database using the client access network, and
is bonded with NET2 port to create the BONDETH0 interface.
•
Port NET2: Provides access to the database using the client access network, and
is bonded with NET1 port to create the BONDETH0 interface.
•
Port NET MGT: Provides access to ILOM using the management network.
When channel bonding is configured for the client access network during initial
configuration, the Linux bonding module is configured for active-backup mode (
mode=1
).
If a different bonding policy is preferred, then you may reconfigure the bonding module
after initial configuration. For configuration details, refer to the Linux Ethernet Bonding
Driver HOWTO in the
/usr/share/doc/kernel-doc-2.6.39/Documentation/
networking/bonding.txt
directory on any Oracle Exadata Database Machine
database server.
The following table shows the port connections for Oracle Exadata Database Machine
Two-Socket Systems database servers when using channel bonding. The client
access network and the backup network must use different ports, in that one network
must use the embedded GbE ports and the other network must use the PCIe ports.
