Abstract
The performance of a computer system which distributes and stores user data and a redundant code is improved. Each computer generates group information indicating positions of a user data region and a redundant code region in each of a plurality of computers; when a write request for write data is received, each computer writes the write data to a local storage device, selects a transmission destination computer on the basis of the group information, and transmits transmission data to the transmission destination computer; when a plurality of pieces of transmission data are respectively received, each computer generates a redundant code by using the plurality of pieces of transmission data on the basis of the group information, and writes the redundant code to the local storage device; and when configurations of the plurality of computers are changed, each computer changes the group information on the basis of the changed configurations.
