Welcome to VMS Software!

Our mission is to develop, sell, and support innovative and advanced releases of OpenVMS, the most secure operating system on the planet. With our “OpenVMS Clearinghouse” Strategy we can provide OpenVMS customers the means to modernize their systems with upgraded licenses and support, Professional Services and Training. We are engaged in this mission with one core motivation: to support and enable our customers in running their mission critical applications at the legendary uptime levels OpenVMS is known for, at maximum performance levels, today and into the future.


In accordance with the Government mandates, the VSI offices in Burlington and in Europe are closed to limit the spread of COVID-19 and all VSI employees are working from home. However, we remain fully operational and available to our customers and partners during this time. There is no impact to customer support. Stay healthy!

The first OpenVMS V9.0 for x86 EAK was released in May 2020. A number of updates have been released since then with more to come.


We sell and distribute software licenses to new releases of the OpenVMS operating system and layered products associated with that OS. We have released multiple versions of VSI OpenVMS for Intel Itanium-based and DEC Alpha-based servers in both English and Japanese. Our R&D group is hard at work on a release for x86. Further in the future, we are exploring other hardware platforms as well.


We provide all levels of support and maintenance services for VMS Software, Inc.'s own releases of the OpenVMS operating system—our first being a version of OpenVMS for Itanium-series servers, running Intel i4 Poulson processors. We also provide support and maintenance services for versions of OpenVMS that are no longer supported by HP.

With a complete long-term solution from HP and VMS Software, customers will now have the flexibility to choose which OpenVMS platform is right for their business...

The genius of VMS and OpenVMS was that [...] clustering was relatively easy to install and use as well as scalable. That cannot be said for most of the commercial scale-out clustering available on the market today.
