VAXcluster Systems

This document serves as a configuration guide for VAXcluster systems running VMS Version 5.5–2. It covers: - System Planning: Definitions of computing environments (interactive, batch, client/server) and how to determine hardware requirements (CPU, memory, I/O). - Components: Detailed information on VAX CPU characteristics, memory, and performance for various VAX families. - Interconnects: Configuration rules and characteristics for Ethernet, CI, DSSI, and FDDI, including mixed-interconnect configurations. - Storage Subsystem Design: Design methodology for storage hierarchies, including capacity estimation, performance optimization (disk striping, caching), and availability (volume shadowing, HSC controllers). - Configuration Rules: Specific requirements and constraints for various interconnects (CI, DSSI, Ethernet, FDDI) to ensure total connectivity and system reliability. - Optimization and Management: Tools and strategies for increasing availability (failover, quorum, environmental protection) and managing system resources (cluster configuration commands, backup strategies, performance monitoring).
