wish to share resources, such as Ethernet connectors, between Test and Development
systems.
For the Production systems, you may dedicate a few of the external 10 GbE connectors
on the gateway switch (for example,
0A-ETH-1
to
0A-ETH-4
). Production systems
will be on one VLAN using these four dedicated 10 GbE external uplinks.
For the Development systems, you may use one Ethernet connector on the gateway
switch and a VLAN of their own. For example,
1A-ETH-3
associated with VLAN ID
10
. In this VLAN, the resources using
1A-ETH-3
are dedicated to Development
systems.
The Test systems require two Ethernet interfaces, and they can use Development's
Ethernet connector
1A-ETH-3
, but on a different VLAN. For example, you can create
two Ethernet interfaces using
1A-ETH-3
associated with a VLAN ID
11
for use by the
Test systems. In this manner, Development systems on their VLAN get their resources
while sharing the Ethernet connector or uplink with Test systems. Since the two
VLANs exist on the same 10 GbE Ethernet link on the gateway switch, any traffic
between the two VLANs should travel through an external router if they are required
to be seen by each other.
Note:
On a single Ethernet connection using the connector on the gateway switch,
you can create up to 4094 VLANs.
11.3 Tag the Ethernet Connectors With a VLAN Identifier
To tag an Ethernet connector on the gateway switch with a VLAN identifier, you must
run the
createvlan
command on the gateway switch that the VLAN will be
associated with.
In this process, you are mapping the following:
• Ethernet connector on the Sun Network QDR InfiniBand Gateway Switch (
0A-
ETH-1
to
0A-ETH-4
, and
1A-ETH-1
to
1A-ETH-4
)
• VLAN ID (2 to 4094)
• InfiniBand partition key (
0xFFFF
)
Note:
Exalogic uses the default partition, and the partition key is
0xFFFF
. You can
associate multiple VLANs to a single Ethernet connector.
For example, you can associate VLAN identifiers
10
and
11
to the same Ethernet
connector
1A-ETH-3
.
To do so, run the
createvlan
command, as in the following example:
1.
Log in to the gateway switch interface as
root
, and run the following commands:
# createvlan 1A-ETH-3 -VLAN 10 -PKEY default
Where
1A-ETH-3
is the Ethernet connector on the gateway switch,
10
is the VLAN
identifier, and
default
is the partition key used in Exalogic.
