Figure 2-4 Topology 4
Figure 2-5 shows all nodes on a public network only.
Figure 2-5 Topology 5
Only two of the five topologies previously shown map to HP Cluster Platform topologies.
Figure 2-6 shows the simplest topology, based on in-band (shared) use of the HP ProCurve switch
as the MPI fabric. The same network provides routing for cluster administrative and job
management traffic. A second network is provided through the site LAN connection.
Figure 2-6 Two-Network Topology
The following cluster features are shown in Figure 2-6:
1
Site LAN connection
2
LAN network, connected to a network interface card (NIC) installed (or embedded) in the
head node
3
The server designated as the head node (control node in HP Cluster Platform terminology)
4
NIC dedicated to the LAN network
