Abstract
A distributed storage system, which receives a write request from a client, includes a plurality of computers which receive power supply from a plurality of power supply units. A first computer, among the plurality of computers, which is a computer that receives the write request from the client, is configured to: cache updated data which is at least apart of data accompanying the write request; select n second computers which are n computers (n is a natural number) among computers each receiving power from a power supply unit different from a power supply unit of the first computer as transfer destinations of the updated data; and transfer the updated data to the selected n second computers, respectively. At least one of the n second computers, when caching the updated data from the first computer, is configured to return a result to the first computer.
