Oracle Solaris Cluster System Hardware and Software Components

Language:

This information is directed primarily to hardware service providers. These concepts can help service providers understand the relationships between the hardware components before they install, configure, or service cluster hardware. Cluster system administrators might also find this information useful as background to installing, configuring, and administering cluster software.

A cluster is composed of several hardware components, including the following:

Cluster nodes with local disks (unshared)
Multihost storage (disks/LUNs are shared between cluster nodes)
Removable media (tapes and CD-ROMs)
Cluster interconnect
Public network interfaces

Figure 2–1 illustrates how the hardware components work with each other.

Figure 2-1 Oracle Solaris Cluster Hardware Components

image:This graphic shows a two-node cluster with public and private networks, interconnect hardware, local and multihost disks, console, and clients.

Administrative console and console access devices are used to reach the cluster nodes or the terminal concentrator as needed. The Oracle Solaris Cluster software enables you to combine the hardware components into a variety of configurations. The following sections describe these configurations.
