Sun Cluster Hardware Environment

The following hardware components make up a cluster:

Cluster nodes with local disks (unshared) provide the main computing platform of the cluster.
Multihost storage provides disks that are shared between nodes.
Removable media are configured as global devices, such as tapes and CD-ROM.
Cluster interconnect provides a channel for internode communication.
Public network interfaces enable the network interfaces that are used by client systems to access data services on the cluster.

Figure 3–1 illustrates how the hardware components work with each other.
