OpenVMS systems and hardware platforms

OpenVMS runs on VAX, Alpha, and Integrity platforms and is currently being ported to the x86-64 platform by VMS Software Inc. (VSI).

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.

VSI are actively developing OpenVMS and provide support for their version of OpenVMS and layered products on Integrity Servers and on Alpha.

The current version from VSI is V8.4-2L3 for HPE Integrity Servers and V8.4-2L1 for AlphaServers, with a V8.4-2L2 "performance release" for Alpha architecture EV6 and later.
