Charon (software)

Charon (software)

Charon (product spelling CHARON) is the brand name of a group of software products able to emulate several CPU architectures. The emulators available under this brand mostly cover the Digital Equipment DEC hardware platforms PDP-11, VAX, and AlphaServer, which support many of the legacy operating systems, including Tru64 and OpenVMS. Charon software products have been developed by the Swiss software company Stromasys SA, which has its headquarter in Plan-les-Quates.

Products and Technology

Even today, DEC systems are frequently used in production despite their sometimes significant age. Some companies use them to support applications that are considered mission critical, for example core applications in banks and stock exchanges, air traffic control systems or manufacturing plants. The aging hardware and changing supplier availability are making the operation of such systems on the original hardware increasingly difficult. Porting the complete solution to new hardware, new operating system, and new programming language (including libraries and interfaces) is often expensive and associated with high risk. A migration to an emulated environment constitutes an alternative solution enabling the use of modern x86 hardware or virtualized standard x86 servers, without having to abandon the fully functioning operating system and the application environment.

The emulators being sold under the product names CHARON-AXP and CHARON-VAX consist of a combination of virtual machine and hardware abstraction layer. They run on Microsoft Windows, Linux or VMware ESXi and provide a virtual PDP-11, VAX, or AlphaServer environment. In a first step, a configuration matching the old system is created on the host platform, thereby creating an emulated guest system behaving like the old physical server. In a second step, the operating system and - as required – associated applications and application data, are moved from the real hardware to the virtual machine. Depending on the operating system, the data is copied as physical image or file system backup. Such migrations are possible without source code changes or operating system upgrades.

In 2010, the IT market research institute Gartner called the CHARON products as leaders in the area of Alpha and VAX platform emulation. Next to Transitive (called IBM PowerVM since the take-over by IBM in 2008) Stromasys, the supplier of CHARON, was also called a major player in overall mainframe emulation technology.

Product Name

Stromasys product name Charon is inspired by Greek mythology. In ancient Greece, Charon was the ferry man, whose task was to transport the dead across the river called Stynx to Hades. The Stromasys emulator provides virtualization of the old DEC hardware allowing old operating systems such as OpenVMS to continue working without change. Figuratively speaking, CHARON “saves“ data and applications and makes them available for future use beyond the life of obsolete hardware.

Vendor

After the take-over of Digital Equipment Corporation (DEC) by Compaq in 1998, which in turn was taken over by Hewlett-Packard in 2002, the former manager Robert Boers bought the DEC European Migration and Porting Center, from which the company Software Resources International was formed. In the beginning, the company offered services for migration projects. After having performed migration, porting, and VMS system programming projects for some time, the company recognised the need for PDP-11 emulators. The development of the first PDP-11 emulator was followed by the development of additional emulators for PDP-11, VAX, and Alpha systems. In 2008 the company was renamed to Stromasys SA, now a public company under Swiss law. Currently, the company has about 80 employees. The company, which was founded in 1998, is still lead by Robert Boers as CTO and head of the supervisory board.
