Sun Cluster Software

Sun Cluster software enables you to 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. The software can 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.
