Abstract
An information processing system includes first to third information processing apparatuses. The first information processing apparatus has a first memory with a cache region and outputs a first power failure signal on detecting a power failure. The second information processing apparatus includes a second memory with a mirror cache region that stores mirror data for the cache region and outputs a second power failure signal on detecting a power failure. The third information processing apparatus monitors the first and second information processing apparatuses and, when both apparatuses have stopped operating, determines whether there is a power failure at the first and second information processing apparatuses based on the first and second power failure signals. When there is no power failure at either apparatus, the first and second information processing apparatuses are restarted in a state where data of the first and second memories is held.
