Claim 6:
7. The computer system according to claim 1,
wherein the processor is configured to:
identify, based on a redundancy degree of protection of data of the capacity pool and the redundancy of the storage controller, a maximum number of groups in the SPGs in a redundant group including the plurality of instances to be subjected to the protection of the data of the capacity pool and the redundancy of the redundant storage controller function, and
determine, in a range equal to or less than the identified maximum number of groups, a number of SPGs constituting the redundant group and a number of instances in the SPG, and make data on the storage device and the redundant storage controller redundant function based on the determined number of SPGs and instances of the number of instances.
