DEC-VAX-4000FamilyOfSystems

This document describes the VAX 4000 Family of Systems, highlighting their performance, value, and investment protection in evolving computing environments.

Key aspects of the VAX 4000 family include:

• Balanced Performance: The systems offer significant increases in CPU and I/O power, leveraging features like dedicated I/O adapters and RISC processors for efficient data access and application response time.
• Investment Protection & Scalability: Designed to evolve with customer needs, the VAX 4000 allows for smooth upgrades (CPU, memory, storage) and is part of the "Alpha-Ready Program," ensuring compatibility and co-existence with future Digital Alpha AXP systems.
• Versatile Deployment: Available in desktop, deskside, and rackmount configurations, they easily integrate into centralized, distributed, real-time, and client/server environments, serving as high-performance, low-cost servers for multi-vendor (OpenVMS, UNIX, Windows, Mac) setups.
• High Availability: Through the OpenVMS operating system and Digital Storage Systems Interconnect (DSSI) Cluster configurations, the VAX 4000 provides high data and system availability crucial for mission-critical business applications, allowing multiple systems (including mixed VAX/Alpha) to be managed as one. DSSI technology provides dedicated control and cache for disks, enhancing I/O performance.
• Ease of Use & Installation: The systems are designed for easy installation and require minimal special facilities, contributing to lower operational costs.

The document also provides detailed technical specifications for various VAX 4000 models, outlining performance metrics, memory capacity, I/O bandwidth, and physical characteristics.
