Modernize Your VAX Environment Without Disrupting Operations

Run your existing OpenVMS VAX systems on modern hardware, virtual machines, or the cloud — with no code changes, no recompiling, and no retraining.

What is vtVAX?

vtVAX is a high-fidelity software emulation platform that replaces legacy DEC VAX hardware with a hardware-independent solution. It recreates the exact system environment your applications expect, allowing your operating system, user interfaces, and layered applications to run completely unchanged.

Compatibility is verified using DEC’s own diagnostic and architecture validation tools, making vtVAX a proven solution for mission-critical and real-time industrial systems.

The Challenge with Legacy VAX Systems

VAX environments continue to power critical operations, but the hardware they rely on is reaching its limits.

  • Aging systems with increasing failure risk
  • Scarcity of replacement parts and expertise
  • Limited network performance and scalability
  • Difficult integration with modern IT infrastructure
  • Growing compliance and security concerns

Streamline Your Systems

vtVAX eliminates dependency on physical VAX systems by moving your environment to modern x86-64 infrastructure.

Your applications continue to run exactly as before, but now on reliable, supported hardware with significantly improved performance and flexibility.

  • No source code conversion
  • No recompiling or relinking
  • No disruption to operations
  • Deploy on-prem, virtualized, or in the cloud

Core Capabilities of vtVAX

  • Full VAX hardware emulation (verified by DEC diagnostics)
  • Support for OpenVMS environments (4.3–7.3)
  • Multiple deployment options (bare metal, VM, cloud)
  • Advanced storage support (SCSI, SAN, NAS, SSD, iSCSI)
  • High-speed networking (1–10 Gbps vs legacy 10 Mbps)
  • OpenVMS clustering support for high availability
  • Serial interface emulation for PLCs and industrial devices
  • Browser-based system management interface
  • Secure, configurable environment with minimal attack surface
