Exalogic Networks

Dear Readers,

My name is Franz Devantier, creator of this blog.  I am an Oracle Certified Professional (OCP DBA 11g) Security DBA.  I will be sharing with you the basic duties of an Oracle DBA, and also some of the undocumented, and not so well known tasks. 

I will make a deal with you:  If you refer me to a company that needs database support, from a few hours per week to full time, and I am able to sign a contract with them.
Then I will give you 10% of the monthly contract or deal price every month.  When the contract ends, and we re-sign the contract, I will again give you 10% of the monthly contract price.  This will go on until the company no longer employs or contracts me or my agents to look after their databases.
I can do this, because that 10% is my marketing budget.  When we re-sign the contract, in the future, it may depend on you giving the thumbs up again, and that is worth 10% of the monthly contract price, to be given to you as commission.
Contact: Franz

Exalogic Networks
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:
-> Bonded bond0 interface over the eth0 interface.
-> Xen bridge interface, xenbr0, on top of bond0.  The xenbr0 interface holds the eth interface IP.
-> Bonded bond1 interface over ib0 and ib2 interfaces.  This is the IPoIB interface for the default InfiniBand partition.

 Network Configuration Performed by the ECU
Network configuration performed by the Exalogic Configuration Utility (ECU), when it configures the Exalogic machine.  You must not modify the system network partitions set by ECU.

appliance
This partition is used for all
interconnections among the
different components of
Exalogic Control.

bond3 for compute
nodes
ipmp3 for storage
appliance
This partition is used
internally to access shares on
the storage appliance. It is
different from the
IPoIB-vserver-shared-sto
rage network.
IPoIB-virt-admin
0x8003
bond4
172.16.0.0/16
This partition is used by
Exalogic Control for all
virtualization management.
IPoIB-ovm-mgmt

bond5
192.168.23.0/24
This partition is used for all
Oracle VM management.
This includes heartbeat,
migration, and virtualization
control.
IPoIB-vserver-sharedstorage
0x8005
bond6 for compute
node, and ipmp4 for
the storage
appliance
172.17.0.0/16
This partition is used to
provide access to Sun ZFS
Storage 7320 appliance for
customer or application
vServers.
EoIB-external-mgmt
0x8006
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
This partition is used to
provide external access to
the VM that is running
Exalogic Control Ops Center
enterprise controller.


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

Network Participation
Network participation of all components in the Exalogic rack and VMs in those networks.  Also information about the InfiniBand partition membership Types.
