"Our virtual Alphas allow you to eliminate your Alpha hardware while retaining your Alpha software unchanged. How cool is that!"

Development: VAX & Alpha Virtualization Solutions

Migration Specialties has built a Hardware Virtualization Layer (HVL) designed to facilitate the development and deployment of legacy hardware emulators. Similar to solutions like VMware®, but targeted at older systems, the HVL can support multiple instances of Legacy Virtual Machines (LVM). Our first LVM releases under the HVL framework are a pair of virtual AlphaServer 400s, FreeAXP™ and Avanti™. More virtual Alpha and VAX solutions will follow. These solutions run under the Microsoft Windows operating system and are fully compatible with virtualzation products such as VMware.

The HVL contains sophisticated technology that simplifies legacy system virtualization, enabling replacemnt of legacy hardware in as little as a few hours. The HVL allows data centers to consolidate old OpenVMS and Tru64 UNIX systems into virtual space on modern hardware without changing the legacy O/S or software applications. It provides immediate benefits in improved reliability, better support options, reduced support costs, reduced power consumption, and recovery of floor space. All of these benefits are available without the need to retrain end users or modify operating procedures.

FreeAXP was released to the public on March 18, 2010. Avanti's public released occured on June 11, 2010.

Migration Specialties virtual OpenVMS and Tru64 UNIX solutions have the support of an international group of organizations, including HP, Intel, Microsoft, XDelta Limited, Strobe Data, BRUDEN-OSSG, Control-X Limited, Caponier Limited, Maindec, PSDS, and RTM-IT.


These are some benchmarks we use to measure performance on FreeAXP, Avanti, SimH VAX, and real hardware. Running these benchmarks unaltered provides a good basis of comparison between systems.
