PRIMECLUSTER provides not only high availability, but scalability as well. PRIMECLUSTER allows multiple nodes to act together to provide a common service. For example, with PAS, you can run a parallel database across multiple nodes. GFS provides you with a cluster wide file system so cooperating processes on multiple nodes can access the same data.
PRIMECLUSTER's scalability is important for customers who find that an application's demand for resources (especially CPU resources) has exceeded the capacity of a single machine. By clustering the nodes, more capacity is available for these types of applications.
