Abstract:
1. A non-transitory computer-readable storage medium storing a program that causes a processor included in a node determining apparatus to execute an operation, the operation comprising: setting a weighting value for each of a plurality of nodes coupled to the node determining apparatus so as to store more data to a node having higher performance, the plurality of nodes being server nodes; storing different data in the plurality of nodes based on a predetermined order determined based on the weighting value; determining a weighting value for a new node when the new node is to be added to the plurality of nodes based on a performance of the new node; updating an order of the weighting value for each of the plurality of nodes based on the weighting value for each of the plurality of nodes and the weighting value of the new node; and causing the different data stored in the plurality of nodes to move to the new node without making movement of data between the plurality of nodes occur, based on the order of the weighting value for the new node.
