OpenVMS systems and hardware platforms

OpenVMS runs on VAX, Alpha, Integrity and x86-64 platforms.

VAX and Alpha can be physical hardware or an emulated environment. No emulators exist for Integrity hardware. x86-64 can be physical hardware or a virtual machine environment.

VMS Software Inc. are actively developing OpenVMS and provide support for their versions of OpenVMS and layered products on x86-64, Integrity and Alpha.

Hewlett-Packard Enterprise (HPE) provide support for versions of OpenVMS up to V8.4 on Alpha and Integrity Servers (up to the -i2 family) and the associated HPE layered products.
