PROBLEM TO BE SOLVED: To provide a technique for optimizing an information network distance between storages that store clients and objects, for application to a cluster storage system having a network base. SOLUTION: A storage system includes at least two or more storage nodes and a network, each of the storage nodes having a means for measuring information network distances to the other storage node and to a client connected to the network. In the storage system, when a client is connected a search is conducted using a query of objects that the client needs, so as to extract objects stored in each storage object and having a high degree of adaptability to the query and to concentrate the extracted objects on the storage node determined to be close to the client by the means for measuring information network distances of the storage nodes.
