Configuring Network Adapters on the Head Node

Updated: June 6, 2006

Applies To: Windows Compute Cluster Server 2003

After installing the Compute Cluster Pack on your head node, the To Do List is displayed. From this dialog you can configure your head node for the network topology on which you have placed your cluster. If public, private, and Message Passing Interface (MPI) network adapters are not assigned, notifications warning the user are displayed.

noteNote
If a private network connecting the nodes of the cluster is unavailable, Windows Compute Cluster Server 2003 supports creation of a cluster on an existing public network (topology scenario 5). However, the Automated Addition method of adding compute nodes to the cluster cannot be used if a dedicated private network does not exist. In this case, compute nodes must be configured manually by installing the Compute Cluster Pack components or by installing an image of a preconfigured compute node on the computer.

Before configuring the appropriate interfaces, ensure that all network adaptors are attached to the appropriate network cable. If you have a topology that supports MPI, make sure that the appropriate high-speed network adapter is attached to the correct network cable.

ImportantImportant
Windows Compute Cluster Server 2003 relies on Internet Connection Sharing (ICS) to provide network address translation between the public and private networks. ICS also provides DHCP service for the private network. ICS is enabled during Compute Cluster Pack setup by selecting Configure Network Address Translation using Internet Connection Sharing (ICS) when using the Network Topology Setup Wizard.

As part of the Compute Cluster Pack installation, if Configure Network Address Translation using Internet Connection Sharing (ICS) is selected, the private interface of the head node is assigned a static IP address: 192.168.0.1 with a subnet mask of 255.255.255.0

ImportantImportant
If you use ICS for Network Address Translation (NAT) and DHCP services, do not change the IP address of the private network interface on the head node. This will cause ICS to fail.

To configure network adapters on the head node

  1. On the Networking tile of the Compute Cluster Administrator To Do List, click Configure Cluster Network Topology (wizard).

  2. On the Before You Begin page of the wizard, note the tasks that you are about to perform, then click Next.

  3. On the Select Setup Type page, choose the compute cluster network topology you want to implement, then click Next. For an explanation of the topologies supported, see Compute Cluster Network Requirements.

  4. On the Configure Public Network page, select the appropriate network adaptor for the public network in the Public Network Adaptor drop-down box. Verify the properties that are displayed for that interface. If correct, click Next.

  5. On the Configure Private Network page, in the Private Network Adaptor drop-down box, select the network adaptor that is connected to the private network. This is the intra-cluster network that you intend to use for cluster node management and deployment traffic.

    If you do not have a private network, select I do not have a private network. Click Next.

  6. On the Configure MPI Network page, select the network adaptor that you want to use for the MPI network.

    If you do not have an MPI network, select I do not have an application network, then click Next.

  7. On the Enable Network Address Translation (NAT) using Internet Connection Sharing (ICS) page of the wizard, if you want to set up ICS NAT on the head node, select Enable Internet Connection Sharing for this cluster. Enabling ICS NAT allows the compute nodes of your cluster to access resources on your public network. Otherwise, select Disable Internet Connection Sharing for this cluster. Then click Next.

  8. On the View Summary page, review the network configuration that is shown. If you are satisfied with the configuration, click Finish. If you want to change something, click Previous until the appropriate page of the wizard is displayed. Correct the information that you want to change, then click Next until you arrive back at the View Summary page and click Finish.

  9. The Progress page is displayed while the network adapters are being configured. When the Result page is displayed, click Finish.

If an error occurs during the configuration of network adapters, a Wizard Not Completed page is displayed. Print, send e-mail, or save the information shown, and correct the conditions which caused the failure. Then run the Network Configuration Wizard again.

If the cluster is installed with a private network and you have created a second disk volume on the head node, and you intend to use the Automated Addition method of adding compute nodes to your cluster, your next steps are to install RIS and then add RIS images. Finish configuration of the head node by adding compute nodes to the cluster and defining cluster administrators and users.

If you do not intend to use the Automated Addition method of adding compute nodes to your cluster, you do not need to install or configure RIS. Finish configuration of the head node by adding compute nodes to the cluster manually (or with some other tool), and then define cluster administrators and users.
