Instalasi Fisik
Banyak buku yang membahas tentang bentuk fisik cluster. Kebanyakan buku dari O'Reilly tentang "Building Linux Clusters" membahas setup fisik cluster, cara memilih motherboard dll. Buku "How to Build a Beowulf" memuat tip yang baik tentang konstruksi fisik cluster.
We favor rack-mounted equipment because of its relative reliability and density. There are Rocks clusters, however, that are built from mini-towers. Choose what makes sense for you.
The following diagram shows how the frontend and compute nodes must be connected:
On the compute nodes, the Ethernet interface that Linux maps to eth0 should be connected to the cluster's Ethernet switch. This network is considered private, that is, all traffic on this network is physically separated from the external public network (e.g., the internet).
On the frontend, at least two ethernet interfaces are required. The interface that Linux maps to eth0 should be connected to the same ethernet network as the compute nodes. The interface that Linux maps to eth1 should be connected to the external network (e.g., the internet or your organization's intranet).
