4301-MBP-DFCM PROSOFT

4301-MBP-DFCM redundancy refers to the repeated configuration of some components of the system. When the system fails, the redundant components intervene and undertake the work of the failed components, thus reducing the failure time of the system. Redundancy means that the system adopts a compound modular structure [1]. When one component fails, the structure can be automatically or manually reconstructed, and another component will replace the failed component to work. The system will be degraded and used, and the rest will still run normally except the failed component.

The redundancy technology of 401-MBP-DFCM is to add more devices to ensure the reliable operation of the system. Redundancy refers to layering different functional modules of the system and adopting redundancy technology. When a functional module of the system fails, the redundant functional module structure is used to replace the failed module, so that the system can work normally. Modularization is a dynamic redundancy technology, which belongs to the category of hardware redundancy. Dynamic redundancy refers to the standard module configuration. Once the fault location is detected and diagnosed, the system can be reorganized or restored, and continue to run normally.

4301-MBP-DFCM is a method of adding certain hardware devices for the purpose of detecting or shielding faults. Common methods are as follows:
One of the fault-tolerant methods of hardware is hardware stacking redundancy, which can be obtained by the repetition of components at the physical level (such as serial and parallel connection of the same components, quadruple components, etc.).
Another method of hardware fault tolerance is called standby redundancy. There are M+1 modules in the system, only one of which is in working state, and the other m modules are in standby state. Once the working module fails, it will be switched to a standby module immediately, and when the replaced reserve module fails, it will be switched to another reserve module until the resources are exhausted. Obviously, this kind of system must have devices for error detection and switching.
4301-MBP-DFCM Hybrid Redundancy System is a combination of accumulation redundancy and standby reserve redundancy. When one of the modules in the stacking redundancy fails, it is immediately cut off and replaced by a fault-free standby module. This method can achieve high reliability.
