Solaris Cluster
From Wikipedia, the free encyclopedia
Solaris Cluster (sometimes Sun Cluster or SunCluster) is a high-availability cluster software product for the Solaris Operating System, created by Sun Microsystems. It is used to improve the availability of software services such as databases, file sharing on a network, electronic commerce websites, or other applications. Sun Cluster operates by having redundant computers or nodes where one or more computers continue to provide service if another fails.
High availability (HA) clusters are distinct from parallel computing clusters (those designed to operate with many systems simultaneously working on portions of the same task). HA clusters are used to provide services that remain available even when individual systems or other components of the cluster fail. Solaris Cluster provides two types of HA services: failover services and scalable services.
Solaris Cluster implementations attempt to build redundancy into a cluster to eliminate single points of failure, including multiple network connections and data storage which is multiply connected via storage area networks.
Solaris Cluster is an example of kernel-level clustering software. Some of the processes it runs are normal system processes on the systems it operates on, but it does have some special access to operating system or kernel functions in the host systems.
In June 2007, Sun released the source code to Solaris Cluster via the OpenSolaris HA Clusters community.[1]
