Looking again at the storage area network, let's assume that it will be deployed at the current reliability (i.e., the targets computed in Chapter 4 were not implemented). When a component of the network fails, it needs to be repaired or replaced. In this example, the primary objective is the restoration of the network; thus, failed components are replaced with new ones and no troubleshooting is done. In other words, all components, including the server, will be looked at as line replaceable units (LRUs) that get replaced upon failure.
