Abstract
A storage system includes an information processing apparatus and plural storage nodes. A replication unit replicates plural data elements respectively stored in plural data regions of one of the plural storage nodes, and stores replicated data elements respectively in plural data regions of each of the other storage nodes. A parity generation unit generates a parity corresponding to the data elements respectively stored in the plural data regions, and stores the parity in the parity region, for each of the storage nodes. The data selection unit selects one or more data regions that hold data elements, from among the plural data regions, and releases one or more non-selected data regions, for each of the storage nodes, so as to reduce a multiplicity of the data elements respectively stored in the plural data regions of each of the plural storage nodes.
