Compute Cluster Network Topology: Scenario 4
Applies To: Windows Compute Cluster Server 2003
All nodes on public, private, and MPI networks
The topology of this cluster topology scenario is similar to scenario 2, with the addition of a high speed MPI network. The head node and all compute nodes have three network interfaces. The private cluster network carries only deployment and management traffic. The MPI network exists, as in scenario 3, to isolate latency-sensitive MPI traffic. This scenario works well for debugging applications running on the cluster, since each compute node has a public interface.
Considerations when using this topology
Improved cluster response because internal cluster network is routed onto the private and MPI networks.
Well-suited to developing and debugging applications because all cluster nodes are connected to the public network.
In this scenario, enabling Internet Connection Sharing (ICS) on the head node is optional. However, if ICS is not enabled and you want to use the Automated Addition method of adding nodes to the cluster, you should configure a DHCP server on the private network to dynamically provide IP addresses to the private interfaces of the compute nodes.
ICS does not provide dynamic IP addresses to the MPI network interfaces of the cluster nodes.
