Cluster Interconnect Speed Requirements

An interconnect path is one network step in the cluster private network: from a node to a node, from a node to a switch, or from the switch to another node. Each path in your cluster interconnect must use the same networking technology, whether Ethernet, PCI-SCI, or Sun Fire Link.

All interconnect paths must also operate at the same speed. This means, for example, that if you are using Ethernet components that are capable of operating at different speeds, and if your cluster configuration does not allow these components to automatically negotiate a common network speed, you must configure them to operate at the same speed.
