The Cost Benefits of Virtualizing Legacy Systems with Charon-PAR

For many organizations, legacy systems like the HP 9000 still power critical business processes. These systems are reliable and familiar—but they also come with growing costs, increasing risks, and limited flexibility. As hardware ages and support becomes harder to find, IT teams are left wondering: is there a smarter way to keep these systems running?

That’s where Charon-PAR comes in.

Built by Stromasys, Charon-PAR is a virtual solution designed to emulate PA-RISC architecture, effectively allowing HP 9000 operating systems and applications to run on modern x86 hardware or even in the cloud. The best part? It does all this without requiring changes to your existing software.

Let’s take a closer look at how virtualizing legacy systems with Charon-PAR can significantly cut costs—and future-proof your infrastructure at the same time.

The True Cost of Sticking with Old Hardware

At first glance, keeping legacy systems alive might seem like the easier—and cheaper—choice. But over time, the hidden costs start to add up. Sourcing replacement parts for aging HP 9000 hardware is difficult, often expensive, and time-consuming. Support staff with experience maintaining these systems are becoming rarer (and pricier) every year.

And then there's energy consumption. Older systems weren’t built with efficiency in mind, which means higher power and cooling costs compared to modern servers or cloud infrastructure, not to mention the risk of unexpected downtime when something finally gives out.

So, while the system itself might still be working, the environment it runs in is anything but sustainable.

What is Charon-PAR, and How Does It Help?

Charon-PAR is a PA-RISC emulator. It mimics the original hardware environment of HP 9000 systems, so your operating system and applications continue to function just as they always have—only now they're running on modern hardware or in a virtual machine.

For IT teams, that means no need to rewrite code, no need to retrain staff, and no need to change how the applications operate. It’s essentially a digital twin of your old system—only faster, more reliable, and much easier to manage.

Cutting Costs Through Virtualization

Using a PA-RISC emulator like Charon-PAR slashes costs in several keyways. First, you no longer need to maintain legacy hardware. That alone can save thousands in replacement parts, service contracts, and the manpower needed to keep everything running.

Second, virtual systems are significantly more energy efficient. You can consolidate workloads, reduce your physical footprint, and cut down on power and cooling bills—all without sacrificing performance.

And let’s not forget disaster recovery. With a virtual HP 9000 system, backups, replication, and failover become easier and more affordable. These are things that just aren’t practical (or even possible) with legacy hardware.

Keeping What Works Without the Risk

One of the biggest advantages of HP 9000 emulation is that it allows businesses to keep their trusted software while ditching outdated hardware. If your applications are still working fine, why invest in a costly and risky migration? With Charon-PAR, you don’t have to.

The emulator runs your existing OS and apps exactly as they were, meaning you get all the reliability of your old setup combined with the benefits of modern infrastructure. It's the best of both worlds: operational continuity with improved performance and lower costs.

Final Thoughts

Using Charon-PAR to virtualize your HP 9000 legacy system is not just a technical improvement, but also a wise financial decision. Businesses can save hardware-related costs, enhance disaster recovery capabilities, save energy costs, and avoid the daunting task of rebuilding existing software by implementing a PA-RISC emulator.

It may be time to think about HP 9000 emulation if you're still using outdated hardware to handle important tasks. Maintaining operations is not enough; you also need to upgrade your legacy infrastructure to increase business value and achieve a competitive edge.
