Connection to the server management interface, a dedicated hardware interface that listens
for, and executes commands received through the Ethernet network. This card is also known
as the management processor (MP), or integrated lights-out (iLO) card, depending on the
model of server. Where supported by the operating environment, this connection is used
for server hardware management functions, such as power-off or boot.
6
NIC dedicated to the Message Passing Interface (MPI)
7
Compute nodes
8
Common Gigabit Ethernet network, used both for MPI traffic, and for in-band job
management, and cluster administrative functions
9
Gigabit Ethernet switch, used as the system interconnect
Figure 2-7 shows a topology based on a dedicated MPI fabric. This might be built around Gigabit
Ethernet or InfiniBand. A second Ethernet network provides routing for cluster administrative,
and job management traffic. A third network is provided through the site LAN connection.
Figure 2-7 Three-Network Topology
The following cluster features are shown in Figure 2-7:
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
5
NIC connected to a dedicated Gigabit Ethernet MPI network, if present
6
Connection to the server management interface, a dedicated hardware interface that listens
for, and executes commands received through the Ethernet network. This card is also
known as the management processor (MP), or integrated lights-out (iLO) card, depending
on the model of server. Where supported by the operating environment, this connection
is used for server hardware management functions, such as power-off or boot.

NIC connected to a shared Gigabit Ethernet MPI network, if present
8
Host Channel Adapter (HCA) card, connected to an InfiniBand MPI network, if present
9
Compute nodes
10
Ethernet network for cluster administration
11
Gigabit Ethernet MPI network, if present
