The Challenges of Relying on Legacy VAX Servers

The VAX/VMS operating systems and applications support mission-critical workloads. Still relying on the aging DEC VAX servers can result in frequent hardware failures, unplanned downtime and escalating maintenance expenses. Replacing the entire legacy hardware is expensive, time-consuming, and risky. Also, the new virtual VAX environment may not be as reliable as the existing hardware, resulting in poor performance. 
 
Charon VAX virtualization solutions from Stromasys are emerging as the global leader in VAX emulation solutions. It mimics original hardware and creates a virtual VAX environment on a modern platform, ensuring seamless business operations.

Seamlessly operates on your mission-critical operations without disruptions or unplanned downtime.

No migration risks & zero changes in the original operating system, applications, or layered products. 

Provides advanced security & disaster recovery measures to protect your business infrastructure.

Ensures operational integrity and smooth integration with modern tools to meet growing market demands.  

Elevates operational performance and efficiency with its scalability, flexibility, and reliability.

Risk-Free Lift and Shift VAX Migration with Stromasys

The Charon-VAX emulation solution is designed on the principle of Lift and Shift legacy migration. It primarily creates a virtual VAX replica of the existing VAX hardware on standard Linux or Windows-based hosts. Its dynamic VAX virtualization capabilities empower you to run the existing binary form, which includes VAX/VMS Operating Systems, their layered products, and applications. 

VAX virtualization will be implemented on the outdated DEC VAX hardware and replaced with an enterprise-grade modern environment (x86 or cloud). The existing OS (OpenVMS) and legacy applications operating on the legacy hardware will run in a new environment without any change. 

Charon-VAX: End Legacy Hardware Failures, Boost Efficiency & Save Big

Stop wasting time, money, and resources on outdated VAX hardware. Run your essential OpenVMS applications on a modern platform (on-prem or cloud) – WITHOUT any application changes.

Charon-VAX Emulation Alternatives for the Following Hardware

The various models of the Charon-VAX emulation family support the appropriate hardware for their architecture.

Emulated Q-Bus and Unibus devices support VAX 3600, MicroVAX II, and similar systems.

Emulated VAX 6000 series support XMI and BI devices.

Memory can be specified to the architectural limits of the emulated systems. 

Storage Subsystems

Virtual storage (container files) – Resides on any storage subsystem presented to the host system.

Physical storage – Local SCSI, SATA, IDE, or any other local storage (including USB) devices allocated to Charon-VAX software.

Virtual storage (container files) – Resides on any storage subsystem presented to the host system.

Additionally, any network-attached storage supported by the host can be utilized, including iSCSI, SAN, NAS, Samba/CIFS, and NFS. Charon-VAX virtualization software also supports OpenVMS Clustering.

Input/ Output Subsystems 

Charon-VAX virtualization provides a variety of networking and character terminal-oriented interfaces, including support for legacy VAX terminals. The Charon-VAX emulator replicates the Ethernet controllers found in the original VAX hardware. Any protocol that runs on these controllers (DECnet, TCP/IP, LAT) will run over a virtualized link. With virtual Charon-VAX,, organizations can replace VAX hardware without hassle, knowing their existing software will operate without modification.  

Test Drive Lift and Shift Migration  

Stromasys has helped hundreds of organizations simplify the support and operations of legacy applications for more than 20 years.

Unleash the power of our VAX/VMS emulator and break free from the challenges of legacy DEC VAX hardware, boosting ROI. 

What If Your Aging SPARC Hardware Fails Tomorrow?

When legacy hardware breaks, there’s no longer any time at all. Regrets arise from not planning ahead.

Don’t let your organization become one of them. Instead of waiting for a failure, be proactive. Get your free assessment before it’s too late.
