DEC-4000-AXP-Servers

This document describes the DEC 4000 AXP Servers, presented as a 21st-century computing solution built around Digital's Alpha AXP 64-bit RISC microprocessor. Designed for both single and multiple users, these servers aim to help organizations achieve higher performance and productivity while optimizing resource usage.

Key features and benefits of the DEC 4000 AXP Servers include:

1. High Performance: They offer exceptional uniprocessor power and symmetric multiprocessing (SMP) capabilities, with high I/O rates (160 MB/s Futurebus+) ensuring balanced system performance. Memory is expandable up to 512 MB (with 2 GB planned for the future).
2. Operating System Flexibility: The systems support both Digital's OpenVMS AXP and the standards-compliant DEC OSF/1 (UNIX), making them suitable for diverse application environments.
3. Scalability and Expandability: Available in pedestal and rackmount configurations, they are designed for maximum expandability. Users can easily add memory and disks, with internal disk storage up to 32 GB and external storage extending to 99.6 GB, with potential for terabyte-range expansion via Futurebus+ storage adapters.
4. High-Capacity Integrated System I/O: They offer extraordinary throughput, supporting multiple fast SCSI-2 buses and various network adapters, including FDDI.
5. High Availability: Features such as clustering (Ethernet-based Local Area Clusters, DSSI), ECC error detection and correction memory, and optional Uninterruptible Power Supply (UPS) ensure robust and reliable operation.
6. Multivendor Integration: The servers are designed to seamlessly integrate with existing VAX, DECsystem, and other vendor systems through comprehensive networking capabilities (e.g., PATHWORKS) and support for industry standards.
7. Investment Protection: Digital offers easy upgrade paths from current models, often requiring only a CPU board exchange.

The DEC 4000 AXP Servers are positioned as a strategic asset for organizations downsizing and adopting distributed computing. They are ideal for both "power-hungry" technical/scientific applications (e.g., seismic analysis, CAD/CAM, simulations, multimedia) and commercial environments requiring cost-effective management of large databases, decision support, and enhanced customer service. The document also provides detailed specifications for various models (610, 620, 710, 720).
