Transport Switches

If you use transport switches, such as a network switch, specify a transport switch name for each interconnect. You can use the default name switchN, where N is a number that is automatically assigned during configuration, or create another name.

Also specify the switch port name or accept the default name. The default port name is the same as the internal node ID number of the Solaris host that hosts the adapter end of the cable. However, you cannot use the default port name for certain adapter types, such as SCI-PCI.

Clusters with three or more voting nodes must use transport switches. Direct connection between voting cluster nodes is supported only for two-host clusters.

If your two-host cluster is direct connected, you can still specify a transport switch for the interconnect.

If you specify a transport switch, you can more easily add another voting node to the cluster in the future.
