Abstract
A multiprocessor system is disclosed that employs an apparatus and method for caging a redundant component to allow testing of the redundant component without interfering with normal system operation. In one embodiment the multiprocessor system includes at least two system controllers and a set of processing nodes interconnected by a network. The system controllers allocate and configure system resources, and the processing nodes each include a node interface that couple the nodes to the system controllers. The node interfaces can be individually and separately configured in a caged mode and an uncaged mode. In the uncaged mode, the node interface communicates information from either of the system controllers to other components in the processing node. In the caged mode, the node interface censors information from at least one of the system controllers.
