A data storage control apparatus and method for reduction of traffic of an interconnect occurring in the timing of a cache miss within a CPU. The apparatus and method are realized by utilizing, as a response to the read request from the CPU, data tags DTAGs used for management of data registered to the cache memory within the CPU under the control of a local node and a retention tag used for holding secondary data indicating that the object data is not held in the cache memory of any CPU of a local node.
