A storage control device includes a first memory, a second memory, and a processor. The processor is configured to store a reference count of each of a plurality of first and second unit data. The processor is configured to arrange first entries of first management information in a first memory area on the first memory. The first entries each include a hash value and information indicating where corresponding one of the first unit data is stored. The processor is configured to arrange second entries of second management information in a second memory area on the second memory. The second entries each include a hash value, information indicating where corresponding one of the second unit data is stored, and the reference count. The processor is configured to arrange, in a third memory area on the first memory, index information for filtering hash values included in the second entries. |

1. A storage control device, comprising:
a first memory; a second memory different from the first memory; and a processor configured to
store, in a storage device, a reference count of each of a plurality of first unit data and each of a plurality of second unit data, the reference count indicating a number of times of writing the respective unit data in the storage device,arrange first entries of first management information in a first memory area on the first memory, the first memory area having a predetermined size, the first entries each including a hash value and information indicating where corresponding one of the plurality of first unit data is stored in the storage device,arrange second entries of second management information in a second memory area on the second memory, the second entries each including a hash value, information indicating where corresponding one of the plurality of second unit data is stored in the storage device, and the reference count regarding the corresponding one of the plurality of second unit data, andarrange, in a third memory area on the first memory, index information for filtering hash values included in the second entries. |
