Figure 4-2 shows the following cluster components:
1. Rack rear view.
2. Rack front view.
3. Blank filler panels fill any unused slots, and are important for maintaining cooling airflow
within the rack.
Caution:
Do not remove filler panels or replace them with additional components. Doing so might
change the thermal characteristics of the rack and cause overheating and data loss.
4. A ProLiant DL3xx-series server, functioning as the cluster's control node.
5. The front view shows the keyboard, video, and mouse (KVM), used locally for cluster
administration operations such as software installation, or when a remote network connection
is not available. An optional 8-port KVM switch lets you connect the KVM to one or more
nodes. This switch is installed at the rear of the rack, behind the KVM with its ports facing
to the front (not as shown in Figure 4-2, which shows the port side of the switch, to illustrate
the component ports.)
6. A 24-port HP ProCurve Ethernet switch, providing the cluster's administrative and console
management networks. In Gigabit Ethernet clusters, such switches also provide the
high-speed message-passing interface (MPI) network.
7. Several ProLiant DL14x-series servers, functioning as the cluster's compute nodes.
8. A 24-port ISR 9024 InfiniBand interconnect from Voltaire. This component provides the
high-speed message-passing interface (MPI) network.
Components not shown in Figure 4-2 include:
