Please refer to your Order and Configuration Guide and Administrator Guide for the configuration and implementation of these architectures. The client LAN and cluster interconnect used in a Compaq Parallel Database Cluster environment can be a combination of redundant or non-redundant architectures. This document begins with a brief discussion of the non-redundant architecture for both the client LAN and cluster interconnect.
Page 4: Communication Points Of Failure
Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server Communication points of failure Several components make up the physical network of the client LAN and cluster interconnect communication paths. The failure of any one of these components renders the entire path inoperable.
Page 5: Supported Non-Fault Tolerant Architectures
Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server Supported Non-Fault Tolerant Architectures A non-fault tolerant architecture means that your cluster will have at least one point of failure in the communications network. Certain non-fault tolerant Ethernet architectures are supported.
Page 6: Supported Fault Tolerant Architecture
A fault tolerant architecture consists of combining Microsoft NT and Compaq software with Compaq Fast Ethernet Network Interface Controllers (NICs) in the Compaq NC Series, to create redundancy. With this configuration, two NICs can be configured for a fault tolerant network with a path for primary and a path for secondary or backup communication on separate NICs (either dual or single port), for each node.
Page 7 Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server Implementing this configuration in the NT environment is achieved through the use of an NT networking feature known as “port teaming”. Port teaming is defined as combining or merging of ports to create a standby or active alternate communication path.
Page 8: Teaming Configuration For Higher Availability
Hardware and Software Requirements Hardware To create a fault tolerant configuration of the cluster, the redundancy option of Compaq’s Fast Ethernet dual-redundant NC series NIC cards is required. To use this function, two dual-port or four single-port (or a combination of both) NICs are required for each server in the cluster.

With ALB, as you add NICs to your server, you can group them in teams to provide up to 400 mbps with a maximum of four Compaq Fast Ethernet NICs. The ALB software continuously analyzes transmission loading on each NIC and balances loading as needed.
Page 10: Steps For Configuring Nics Utilizing Teaming
Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server Steps for Configuring NICs Utilizing Teaming Click the Start menu and go to Control Panel under the Settings menu. Double click the Network control panel. Click on the Adapters tab. All of the installed NICs should be listed.
Page 11 Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server This takes you to the Compaq Network Teaming and Configuration Utility main window. All of the installed NICs are listed again. You are now ready to build a team. To do so, make sure the different NICs are all on the same network and running at the same speed.
Page 12 Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server This takes you to the Properties window. Select the Teaming Controls tab (default tab). Then select either Fault Tolerant for the NFT option or Load Balancing for the ALB option. ALB is the recommended option.

Supported Ethernet Interconnects for Compaq Parallel Database Clusters using Oracle Parallel Server Verifying Client LAN and Cluster Interconnect IP Addresses Verify that the IP addresses for the client LAN and cluster interconnect are correctly assigned by pinging the machine host name. (You can find the machine host name by selecting the Identification tab in the Network control panel.)
