Cabling the Ethernet Cluster Interconnect
A PDC/O2000 running Oracle8i software uses an Ethernet cluster
interconnect.
The following components are used in a non-redundant Ethernet cluster
interconnect:
■ One Ethernet adapter in each cluster node
■ Ethernet cables and a switch or hub
G For two-node PDC/O2000 clusters, you can either use one Ethernet
crossover cable or one 100-Mbit/second Ethernet switch or hub and
standard Ethernet cables to connect the two servers.
G For PDC/O2000 clusters with three or more nodes, you use one
100-Mbit/second Ethernet switch and standard Ethernet cables to
connect the servers.
The following components are used in a redundant Ethernet cluster
interconnect:
■ Two Ethernet adapters in each cluster node
■ Ethernet cables and switches or hubs
G For two-node PDC/O2000 clusters, you can use two 100-Mbit/sec
Ethernet switches or hubs with cables to connect the servers.
G For PDC/O2000 clusters with three or more nodes, you use two
100-Mbit/sec Ethernet switches connected by Ethernet cables to a
separate Ethernet adapter in each server.
NOTE: In a redundant Ethernet cluster configuration, one Ethernet crossover cable must
be installed between the two Ethernet switches or hubs that are dedicated to the cluster
interconnect.
To connect two nodes in a non-redundant Ethernet cluster interconnect using
an Ethernet crossover cable:
1. In both nodes, install the Ethernet crossover cable into the port on the
Ethernet adapter that is designated for the Ethernet cluster interconnect.
2. If you have a dual-port Ethernet adapter in each node, you can use the
second (lower) port on each to connect to a client LAN hub or switch.
