► RS/6000 44P Model 170 (7044-170) A High Availability Control Workstation (HACWS) option is also available on configurations with SP standard frames only. For more information, refer to Chapter 7, “Control workstations” on page 195. 1.5 RS/6000 SP and AIX clustering The new e-business environment creates the need for a computing infrastructure comprised of servers that optimize three classes of workloads: Data transaction servers to manage core business processes; web application servers to manage end-user experience; and appliance servers to manage specific network functions. The environment must provide essential computing attributes that enable seamless integration and management of end-to-end web infrastructure. Computing resources in this diverse computing environment must be managed to effectively balance complex workloads as well as deliver the required Quality of Service (QoS), Capacity on Demand (CoD), security, scalability and manageability. This aggregation or clustered computing, include servers, operating systems, storage, networks, applications, racks and stacks. The emergence of Web serving and e-business as mainstream application workloads has dramatically increased the value and relevance of clustered computing. Clustered computing now includes “tight clusters” (as RS/6000 SP) for high availability and single application scalability, “loose clusters” (as dense computing elements in racks) for appliances and web infrastructure, and “grid clusters” (heterogeneous, distributed collection of computing resources) for e-utilities and terascale applications. These diverse cluster solutions must deliver the needed attributes of QoS, CoD, security, scalability, and manageability. On the <strong>IBM</strong> AIX operating system environment, we may consider the following different cluster computing models and their main characteristics: ► Sequential and Distributed Applications (little or no application alteration is required) – Load Balancing Cluster Scale number of users or transactions throughput through application replication Allocation of incoming transactions based on load-balancing algorithms Figure 1-4 illustrates a load balancing cluster. 18 RS/6000 SP and Clustered <strong>IBM</strong> ^ pSeries Systems Handbook
