Why Virtualize?

Your VAX and Alpha systems have served you well for years, if not decades. They have returned your investment in them many times over.

But if you have responsibility for your company's operations or its bottom line then you understand the stress that goes with legacy hardware ownership. Nothing lasts forever.

Virtualization technology works. In the last decade there has been a proliferation of virtual solutions for hardware, operating systems, storage, even video games.

Only a few of these offerings replace legacy hardware. Many virtualize brand new technologies simply because virtualization saves money and space.

For VAX and Alpha system owners, the topic is more urgent. It's not just a conservation issue. It's a preservation issue. You need to find a way to keep your OpenVMS based applications running to maintain your business. This is where we can help you!

Your OpenVMS operating system, DEC layered software, third-party packages and homegrown user applications execute unmodified on vtVAX and vtAlpha. No code conversion is required. Users do not need to be retrained.
