The Cluster 1350 can have a maximum of 512 nodes in addition to the one
required Management Node. All nodes run the Linux operating system.
The Cluster 1350 identifies two types of cabinet: Primary and Expansion. A cabinet
is called Primary if it contains the Management Node and console monitor.
Expansion cabinets may contain Storage Nodes or mass-storage devices as well as
computing nodes called Cluster Nodes. Expansion cabinets do not contain a
Management Node or console. Figure 1 on page 4 shows an example of a Primary
cabinet. Figure 2 on page 5 shows an example of an Expansion cabinet containing
Cluster Nodes.
Figure 3 on page 6 shows an example of an Expansion cabinet containing storage
controllers and mass storage.
