Single point of failure. In this diagram the router is a single point of failure for the communication network between computers. A single point of failure (SPOF) is a part of a system that, if it fails, will stop the entire system from working. [1] SPOFs are undesirable in any system with a goal of high availability or reliability, be it a ...
No single point of failure – If a system experiences a failure, it must continue to operate without interruption during the repair process. Fault isolation to the failing component – When a failure occurs, the system must be able to isolate the failure to the offending component. This requires the addition of dedicated failure detection ...
graph with an example of steps in a failure mode and effects analysis. Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects.
Elimination of single points of failure. This means adding or building redundancy into the system so that failure of a component does not mean failure of the entire system. Reliable crossover. In redundant systems, the crossover point itself tends to become a single point of failure. Reliable systems must provide for reliable crossover.
A cascading failure is a failure in a system of interconnected parts in which the failure of one or few parts leads to the failure of other parts, growing progressively as a result of positive feedback. This can occur when a single part fails, increasing the probability that other portions of the system fail. [1][2] Such a failure may happen in ...
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
Jesus nut is a slang term for the main rotor retaining nut[1] or mast nut, which holds the main rotor to the mast of some helicopters. The related slang term Jesus pin refers to the lock pin used to secure the retaining nut. More generally, Jesus nut (or Jesus pin) is used to refer to any component that is a single point of failure and whose ...
Some genetic diseases are named more precisely, and represent a single point of failure on a metabolic pathway. For example, Tay–Sachs disease, GM2-gangliosidosis, AB variant, and Sandhoff disease might easily have been defined together as a single disease, because the three disorders are associated with failure of the same enzyme and have ...
