The following requirements and restrictions apply to Sun Cluster configurations that use InfiniBand adapters:
A two-node cluster must use InfiniBand switches. You cannot directly connect the InfiniBand adapters to each other.
Sun InfiniBand switches support up to nine nodes in a cluster.
Jumbo frames are not supported on a cluster that uses InfiniBand adapters.
If only one InfiniBand adapter is installed on a cluster node, each of its two ports must be connected to a different InfiniBand switch.
If two InfiniBand adapters are installed in a cluster node, leave the second port on each adapter unused. For example, connect port 1 on HCA 1 to switch 1 and connect port 1 on HCA 2 to switch 2.
VLANs are not supported on a cluster that uses InfiniBand switches.
