Redundant Ethernet cluster interconnect for a two-node
PDC/O5000 cluster
These components include two dual-port Ethernet adapters in each cluster
node. The top port on each adapter connects by Ethernet cable to one of two
Ethernet switches or hubs provided for the cluster interconnect. The bottom
port on each adapter connects by Ethernet cable to the client LAN for the
cluster. A crossover cable is installed between the two Ethernet switches or
hubs used in the Ethernet cluster interconnect.
