x86: Oracle Solaris Cluster Topologies

A topology is the connection scheme that connects the cluster nodes to the storage platforms that are used in the cluster. Oracle Solaris Cluster supports any topology that adheres to the following guidelines.

  • Oracle Solaris Cluster software supports from one to eight cluster nodes in a cluster. Different hardware configurations impose additional limits on the maximum number of nodes that you can configure in a cluster composed of x86 based systems. See Oracle Solaris Cluster Topologies for the supported node configurations.

  • Shared storage devices must connect to nodes.

Oracle Solaris Cluster does not require you to configure a cluster by using specific topologies. The following clustered pair topology, which is a topology for clusters that are composed of x86 based nodes, is described to provide the vocabulary to discuss a cluster's connection scheme. This topology is a typical connection scheme.

The following section includes a sample diagram of the topology.
