Tandem System


Classification Key : Exterior Security, Tampering

Problem

Failure in one component often starts the domino-effect and the failure is propagated to bring about the entire system failure. How can the system be made tolerant to this fault?

Solution

Structure a system so that an independent failure of one component will be detected quickly and so that an independent single-component failure will not cause system failure. Use multiple components to perform the tasks and report the result only if the result is similar for both the components.

Known Uses

Tandem Nonstop operating system.
