Configure Ethernet Over InfiniBand
This chapter describes how to set up Ethernet over InfiniBand (EoIB) network
configuration for your Exalogic machine.

10.1 Introduction to Virtual NICs (VNICs)
A virtual NIC or VNIC maps an Ethernet connector on the Sun Network QDR
InfiniBand Gateway Switch to a network interface within the compute node. A
connector (
0A-ETH-1
to
0A-ETH-4
, and
1A-ETH-1
to
1A-ETH-4
) hosts a 10 GbE
port. In the Exalogic machine, on each Sun Network QDR InfiniBand gateway switch,
you can have a maximum of eight 10 GbE uplinks. In most scenarios, the number of 10
GbE uplinks is less than 8.
One or more VNICs can be assigned to a compute node. If more than one VNIC is
assigned, they can be different connectors on the same Sun Network QDR InfiniBand
Gateway Switch or on different Sun Network QDR InfiniBand Gateway Switches. The
default configuration is to map one connector on each of the two switches and to bond
or balance the pair for increased availability.
Note:
In Exalogic, you create VNICs in Sun Network QDR InfiniBand Gateway
Switch manual mode.
10.1.1 VNIC Resource Limit
On each Sun Network QDR InfiniBand Gateway Switch there can be a maximum of
1K VNICs per logical gateway. Logical gateway denotes either a single external
Ethernet port or a defined group of external Ethernet ports. The 1K limit is shared by
all VLANs on the logical gateway and each defined VLAN ID also consumes one of
the 1K VNICs. For more information on VLANs see
To find out how many VNICs are currently defined, use the
showvnics
command
and for VLANs, use
showvlan
.
