5/23/2023 0 Comments Rbd wikiIf a path may be found through the network of switches from beginning to end, the system still works.Īn RBD may be converted to a success tree or a fault tree depending on how the RBD is defined. Īn RBD may be drawn using switches in place of blocks, where a closed switch represents a working component and an open switch represents a failed component. By contrast, any failure along a series path causes the entire series path to fail. For example, a group of parallel blocks could require two out of three components to succeed for the system to succeed. RBDs will indicate the type of redundancy in the parallel path. Each block represents a component of the system with a failure rate. Parallel blocks indicate redundant subsystems or components that contribute to a lower failure rate. An RBD is drawn as a series of blocks connected in parallel or series configuration.
