Guidelines for OpenVMS Cluster Configurations

This document provides configuration guidelines for OpenVMS Cluster systems, focusing on optimizing availability, scalability, and performance. Key topics include:

• System Configuration: Hardware and software component requirements for OpenVMS Clusters across VAX, Alpha, and I64 architectures.
• Interconnects: Detailed analysis of cluster interconnect options, including CI, SCSI, Fibre Channel, Ethernet/Gigabit Ethernet, ATM, and FDDI.
• Storage Subsystems: Strategies for choosing storage, determining capacity, and configuring high-availability storage subsystems.
• Multipath Configurations: Procedures for configuring multiple paths to SCSI and Fibre Channel storage to enhance availability and load balancing.
• Cluster Management: Strategies for system disk management, common environments, quorum, and system transition management.
• Multiple-Site Clusters: Guidelines for deploying multiple-site clusters using WAN technologies like ATM and DS3.

It serves as a technical resource for architects and system managers planning or maintaining OpenVMS cluster infrastructures.
