System resources within a cluster are dynamically assigned to recognize application priority and efficiently balance workloads,manage job flow and satisfy unpredictable demands. At its busiest hour, the system smoothly handled 1.2 million hits per minute. Central system management Linking computers together into a cluster can simplify their management. It is important to be able to work with the individual components of a cluster,as well as with the cluster as a whole. Clusters provide a means for easier management of computing resources,while not restricting the potential capabilities of the system.
Clusters offer the important capability of recovery from disasters.
Improves investment protection and reduces total cost of ownership AIX-based clusters provide protection of IT investments. Also,old nodes can be mixed with new nodes,thus allowing clusters to be upgraded incrementally and affordably. Different levels of AIX can be run on different nodes in the cluster, allowing test workloads to be isolated from production workloads. New software or hardware can be fully tested before it is put into production. Along with the benefit of lower cost for cluster building blocks,clustering also enhances the total cost of ownership by addressing staff concerns.
