Introduction to the Oracle Solaris Cluster Environment

The Oracle Solaris Cluster environment extends the Oracle Solaris Operating System into a cluster operating system. A cluster is a collection of one or more nodes that belong exclusively to that collection.

A cluster offers several advantages over traditional single-server systems. These advantages include support for failover and scalable services, capacity for modular growth, the ability to set load limits on nodes, and low entry price compared to traditional hardware fault-tolerant systems.

Additional benefits of the Oracle Solaris Cluster software include the following:

In a cluster that runs on the Oracle Solaris OS, a global cluster and a zone cluster are types of clusters. A global cluster consists of a set of Solaris global zones, while a zone cluster consists of a set of non-global zones (one per global-cluster node), which are configured to behave as a separate “virtual” cluster. For more information about global and zone clusters, see Overview of Administering Oracle Solaris Cluster in Oracle Solaris Cluster System Administration Guide and Working With a Zone Cluster in Oracle Solaris Cluster System Administration Guide.
