Configuring Networking

Updated: September 29, 2010

The Configure Networking task area allows you to configure networking for each node of the storage failover cluster.

Typical storage network configurations include using two, four, or six network interface cards (NICs). All storage network configurations must include one dedicated network for heartbeat and one or more networks for file, high availability (HA) file server, or iSCSI access. The heartbeat network can be implemented by using a crossover cable that is supplied by your storage appliance vendor.

Network settings are automatically configured in Windows Storage Server 2008 R2 if your storage appliances use DHCP to assign IPv4 addresses. If you are configuring networking for a remote storage appliance, you may need to manually configure the network settings.

When you configure storage appliances for failover clustering, we recommend that you have one separate network interface for cluster communications and one or more network interfaces for public communications.

For more information about networking for failover clusters, see the Windows Storage Server 2008 R2 Getting Started Guide (

Some network connection settings may be specific to your storage appliance. Consult the documentation that is provided by your storage appliance vendor for specific information as applicable.
