When the concept of wear leveling is applied in the distribution of the work load to information-processing devices in an information-processing system having a first information-processing device that writes information to a first storage device equipped with a nonvolatile memory and a second information-processing device that writes information to a second storage device equipped with a nonvolatile memory, the service life of the nonvolatile memories of the first information-processing device and the second information-processing device is expended virtually simultaneously, thereby hindering the continuous operation of the system. This information-processing system, which has a first counter that counts the number of instances of writing to the first storage device and a second counter that counts the number of instances of writing to the second storage device, solves the aforementioned problem by allocating the work load to the first information-processing device and the second information-processing device on the basis of the replacement period for the first storage device, the replacement period for the second storage device, the output from the first counter, and the output from the second counter. |
