Fault Tolerance
Nevista delivers Marathon system-level fault tolerance (FT) to protect mission-critical applications that cannot afford even a brief interruption in service. With system-level fault tolerance, your Windows Server application runs redundantly on both servers. Even when an entire server fails, you experience continuous availability — no loss of application state, no loss of data. This solution is often used in regulated industries that require them to have fault tolerant servers to prevent loss of any data, even ‘in-flight' transactions. Nevista also helps organizations meet data protection regulations by ensuring 100% data acquisition and retention.
FT Solution pools the physical resources of two or more standard Windows servers into a single, unified operating environment. It virtualizes these servers to appear and operate as one for the purpose of ensuring continuous availability for Windows applications. The environment appears and operates as though the applications were running on a single stand-alone server with one identity and one IP address.
