Clustering software is typically used on multiple interconnected servers so that they appear as if they are one server to end users and applications. For the SPARC SuperCluster T4-4, clustering software is used to cluster certain logical domains on the SPARC T4-4 servers together with the same type of domain on other SPARC T4-4 servers. The benefits of clustering software include the following:
Reduce or eliminate system downtime because of software or hardware failure
Ensure availability of data and applications to end users, regardless of the kind of failure that would normally take down a single-server system
Increase application throughput by enabling services to scale to additional processors by adding nodes to the cluster and balancing the load
Provide enhanced availability of the system by enabling you to perform maintenance without shutting down the entire cluster
The SPARC SuperCluster T4-4 uses the following clustering software:
