About Sun Cluster Software

Sun™ Cluster software lets you connect up to eight Sun servers in a cluster configuration. A cluster is a group of nodes that are interconnected to work as a single, highly available and scalable system. A node is a single instance of Solaris software—it may be running on a standalone server or on a domain within a standalone server. With Sun Cluster software, you can add or remove nodes while online, and mix and match servers to meet your specific needs.

Sun Cluster software delivers high availability through automatic fault detection and recovery, and scalability, ensuring that mission-critical applications and services are always available when needed.

With Sun Cluster software installed, other nodes in the cluster will automatically take over and assume the workload when a node goes down. It delivers predictability and fast recovery capabilities through features such as local application restart, individual application failover, and local network adapter failover. Sun Cluster software significantly reduces downtime and increases productivity by helping to ensure continuous service to all users.

The software lets you run both standard and parallel applications on the same cluster. It supports the dynamic addition or removal of nodes, and enables Sun servers and storage products to be clustered together in a variety of configurations. Existing resources are used more efficiently, resulting in additional cost savings.

Sun Cluster software allows nodes to be separated by up to 10 kilometers. This way, in the event of a disaster in one location, all mission-critical data and services remain available from the other unaffected locations.

About Communicating With the System

To install your system software or to diagnose problems, you need some way to interact at a low level with the server. The system console is Sun’s facility for doing this. You use the system console to view messages and issue commands. The system console is unique—there can be only one per system.
