Title: COMPUTER SYSTEM, DATA ALLOCATION MANAGEMENT METHOD, AND PROGRAM
Abstract:
The purpose of the invention is to achieve in cloud computing a computer system that automatically sets a KVS configuration taking into account the differences in performance among computers. This computer system is configured by connecting a plurality of computers over a network and uses a database formed from storage areas of the computers to perform a task. Each computer holds performance management information for managing the performance of the computers. Each computer constituting the database has master data and copy data of master data of another computer allocated thereto. The computer system includes a performance information management unit that updates the performance management information, and a cluster configuration management unit that determines, on the basis of the performance management information, a first management range for the master data managed by a first computer and a second computer that holds copy data of the master data managed by the first computer.
