Ethernet Cluster Interconnect Adapters
To implement the Ethernet cluster interconnect, each cluster node must be
equipped with Ethernet adapters capable of 100-Mbit/second transfer rates.
Some adapters may be capable of operating at both 10-Mbit/second and
100-Mbit/second; however, Ethernet adapters used for the cluster interconnect
must run at 100-Mbit/second.
The Ethernet adapters must have passed Windows 2000 Advanced HCT
certification.
NOTE: If you are using dual-port Ethernet adapters in a non-redundant Ethernet cluster
interconnect, you can use one port for the Ethernet cluster interconnect and the second
port for the client LAN. Refer to the technical white paper Supported Ethernet
Interconnects for Compaq Parallel Database Clusters Using Oracle Parallel Server for
detailed information about configuring redundant Ethernet cluster interconnects. This
document is available at
www.compaq.com/support/techpubs/whitepapers
For detailed information about installing an Ethernet cluster interconnect, see
Chapter 5, “Installation and Configuration.”
Ethernet Switch
IMPORTANT: The Ethernet switch or switches used with the Ethernet cluster
interconnect must be dedicated to the cluster interconnect. They cannot be connected to
the client network (LAN) or to servers that are not part of the PDC/O2000 cluster.
When an Ethernet cluster interconnect is used in a cluster with three or more
nodes, a 100-Mbit/second Ethernet switch is required for the cluster
interconnect path. The 100-Mbit/second Ethernet switch handles the higher
network loads essential to the uninterrupted operation of the cluster. An
Ethernet hub cannot be used.
