Guidelines for OpenVMS Cluster Configurations

This document provides extensive guidelines for configuring and managing OpenVMS Cluster systems. It covers a wide range of topics, including:

• System Configuration: Hardware and software components, mixed Alpha and VAX clusters, and general configuration rules.
• Business & Application Requirements: Planning for availability, scalability, performance, and physical constraints.
• Cluster Interconnects: Comparative analysis of interconnects (CI, Fibre Channel, SCSI, DSSI, LAN, MEMORY CHANNEL) and configuration guidelines for high performance and availability.
• Storage Subsystems: Storage product choices, capacity planning, performance optimizers, and multipath configurations for SCSI and Fibre Channel storage.
• Configuration for High Availability: Strategies for creating highly available clusters, including component redundancy, failover mechanisms, and multi-site configurations.
• Scalability: Strategies for scaling system, storage, and interconnect dimensions, including cluster management with satellites.
• System Management: Strategies for system disk configuration, environment management, quorum, and state transitions.
• Technical Appendices: Detailed technical information for SCSI as a cluster interconnect, MEMORY CHANNEL, CIPCA, and multiple-site configurations.
