Compaq Parallel Database Cluster Model PDC/O2000 for Oracle8i and Windows 2000 Administrator Guide

Cluster Architecture 2-71
Non-Redundant Ethernet Cluster Interconnect
Components
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.
Redundant Ethernet Cluster Interconnect
Components
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/second 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/second 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.
