The VOS operating system runs on Stratus Continuum and ftServer V Series systems.  Stratus Continuum 600 and 1200 servers running the VOS operating system have long been valued for their ability to deliver industry-leading uptime.  Now Stratus introduces the ftServer V Series systems, a new VOS-based server option intended specifically for applications that are running up against performance or capacity limits.  Perfected by two decades of engineering enhancements, VOS works seamlessly and transparently with the availability, reliability, and serviceability features built into every Stratus Continuum and V Series system, ensuring continuous availability for mission-critical applications.

As key components of Stratus' availability strategy, VOS and the Stratus fault-tolerant architecture were expressly designed to complement and strengthen each other.  Together, they provide maximum availability and performance, even in the face of failure and reconfiguration.

VOS enables developers to bring applications into production quickly and simply. VOS supports open-system flexibility and capability for languages and communications as well as a comprehensive range of WAN and LAN protocols for distributed environments. Open StrataLINK^® with TCP/IP software enables Stratus modules and systems to communicate in a standard network environment.
