VAX (Virtual Address eXtension) is a venerable family of 32-bit computers from HP (via Digital and Compaq acquisitions) introduced in 1977 with the VAX-11/780.

VAX models ranged from desktop units to mainframes all running the same VMS operating system. Large VAX multiprocessing clusters served thousands of users in real-time Throughout the 1980s, software compatibility between all models caused the VAX family to achieve outstanding success for Digital. The last VAX order was taken in 1999 (for VAXstation 4000s), 22 years after the first VAX. HP has expressed support for OpenVMS on VAX through 2010.

Comware offers two separate and distinct approaches to replace your legacy VAX. Depending on your VAX system configuration and software application, one of these two offerings will solve your VAX support and performance issues forever.

vtVAX Emulator (Software)

The REVIVER vtVAX emulator is a cost-effective replacement for almost any DEC VAX server or workstation. This affordable VAX virtualization software runs on modern PCs, reducing maintenance and operating cost and yielding ‘green’ benefits for both the data center and the bottom-line. The OpenVMS operating system, user interface and applications run unmodified on the REVIVER VAX emulator. No conversion of VAX source code is required. No retraining is required. Your investment is protected.

The REVIVER vtVAX emulator runs on a general purpose computer with the x86-architecture (32 or 64-bit). You are no longer locked in; you can now easily move to a more common platform and integrate your VAX systems in the IT infrastructure of your organization.

VAX on a Board

NuVAX Model 1200 is a brand new processor that replaces your VAX processor, memory, disks and tape drives in the VAX chassis. Your applications are transferred onto NuVAX’s self-contained hard drive and run without modification with VAX emulation software. Existing specialized Q-bus controllers and equipment are supported without any configuration changes.

This model is suited for applications embedded in computer bays where packaging and cabling changes are not practical. The Model 1000 allows you to retain your VAX chassis, Q-bus controllers, and cables.

VAX Replacement System

NuVAX Model 4400 is a complete VAX system replacement for the VAX chassis, CPU, memory, mass storage, and Q-bus controllers. Your applications are transferred without modification onto a NuVAX system which replaces the VAX. Remaining Q-bus controllers are replaced with new PCI controllers that are software and hardware compatible with Q-bus interfaces such as DRQ3B, DRV11-WA, and IEQ11. These new controllers connect to your existing equipment without software configuration changes.
