How to Install Ethernet or InfiniBand Transport
Cables and Transport Junctions
Use this procedure to install Ethernet or InfiniBand transport
cables and transport junctions (switches).
- If not already installed, install transport
adapters in your cluster nodes.
See the documentation
that shipped with your host adapters and node hardware.
- If necessary, install transport junctions and optionally
configure the transport junctions' IP addresses.
Note - (InfiniBand Only)
you install one InfiniBand adapter on a cluster node, two InfiniBand
switches are required. Each of the two ports must be connected to
a different InfiniBand switch.
If two InfiniBand
adapters are connected to a cluster node, use only one port on each adapter for the interconnect and
have it connected to an InfiniBand switch. The second port of the adapter can be connected but must
not be used as an interconnect. Do not connect ports of the two InfiniBand adapters to the same
- Install the transport cables.
- (Ethernet Only) As
the following figure shows, a cluster with only two nodes can use
a point-to-point connection, requiring no transport junctions.

Only) Typical Two-Node Cluster Interconnect
(Ethernet Only) For a point-to-point
connection, you can use either UTP or fibre. With fibre, use a standard
patch cable. A crossover cable is unnecessary. With UTP, see your
network interface card documentation to determine whether you need
a crossover cable.
Note - (Ethernet Only) You
can optionally use transport junctions in a two-node cluster. If
you use a transport junction in a two-node cluster, you can more
easily add additional nodes later. To ensure redundancy and availability,
always use two transport junctions.
- As the following figure shows, a cluster with more than
two nodes requires transport junctions. These transport junctions
are Ethernet or InfiniBand switches (customer-supplied).

To install and configure the Oracle Solaris Cluster software with the
new interconnect, see Chapter 2, Installing Software on Global-Cluster Nodes, in Oracle Solaris Cluster Software Installation Guide
(Ethernet Only) To configure
jumbo frames on the interconnect, review the requirements in Requirements When Using Jumbo Frames and
see the Sun GigaSwift documentation for instructions.
