Example System ServerNet Pathways
In a second scenario, if the one of the ServerNet adapters fails, only the Fibre Channel
or Ethernet devices that are connected to the failed adapter are affected. The failure
has no effect on the other resources on the same or the other ServerNet fabric.
This illustration shows a logical representation of a complete typical 4-processor triplex
