Using Dual-Port Network Adapters for the Private Network

You can configure your cluster to use the public network as a failover for private network communications. However, dual-port network adapters are not supported in the private network.

Verifying Cluster Network Communications

To ensure proper cluster operations, the cluster nodes must be able to communicate with each other through the private network (cluster interconnect). This communication involves the exchange of heartbeat messages, whereby the two cluster nodes inquire about each other's status, or "health," and acknowledge each inquiry.

To verify network communications between the cluster nodes:

1Open a command prompt on each cluster node.

2At the prompt, type: ipconfig /all

3Press <Enter>.

All known IP addresses for each local server appear on the screen.

4Issue the ping command from each remote system.

Ensure that each local server responds to the ping command.

Configuring the Internet Connection Firewall

The Microsoft Windows Server 2003 Enterprise x64 Edition and Windows Server 2003 Enterprise Edition operating systems with Service Pack 1 include an enhanced Internet Connection Firewall that can be configured to block incoming network traffic to a PowerEdge system. To prevent the Internet Connection Firewall from disrupting cluster communications, additional configuration settings are required for PowerEdge systems that are configured as cluster nodes in an MSCS cluster.
