The data processing unit holds the operation data group belonging to the responsible group as an operation cache data group, the data storage unit stores a redundant data group that is a copy of the operation data group belonging to the responsible group in a data storage unit of a server device that does not store the redundant data group, and the data processing unit holds a redundant cache data group that is a copy of a redundant data group belonging to a second non-responsible group that is different from the group to which the redundant data group belonging to a first non-responsible group which is stored in the data storage unit.SELECTED DRAWING: Figure 1
