Abstract
A storage control system reads a data set from a storage apparatus if necessary in response to an I/O request. A data set contains data and an address. The storage control system performs an all-type address check which is a check to determine whether one of a first address and second address which correspond to a read-target data set in address translation information, which is information indicating a mapping relationship between one or more first addresses and one or more second addresses, matches the address among the data and address contained in the data set. The one or more first addresses are each an address which belongs to the first address type. The one or more second addresses are each an address which belongs to the second address type. The storage control system performs processing according to the I/O request when the result of the all-type address check is true.
