Flexibility OpenVMS Cluster computing environments offer compatible hardware and software across a wide price and performance range. Scalability You can add processing and storage resources without disturbing the rest of the system. You control the level of performance and availability as you expand. Ease of management OpenVMS Cluster management is efficient and secure. Because you manage an OpenVMS Cluster as a single system, many tasks need to be performed only once.
Clusters automatically balance user, batch, and print work loads.
An OpenVMS Cluster system comprises many hardware components, such as systems, interconnects, adapters, storage subsystems, and peripheral devices. Table 1-2 describes these components and provides examples. See Chapter 3 for more information about Digital's OpenVMS systems. OpenVMS Cluster systems can contain any supported Alpha, VAX, or MicroVAX system, including SMP systems. The hardware connection between OpenVMS Cluster nodes over which the nodes communicate.
