Clustering software is used on multiple interconnected servers so that they appear to end users and applications as one server. For SuperCluster systems, clustering software clusters certain logical domains on the compute nodes together with the same type of domain on other compute node. The benefits of clustering software include:
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.
SuperCluster M8 and SuperCluster M7 use the following clustering software:
