COMPUTER SYSTEM AND METHOD OF CONTROLLING COMPUTER SYSTEM

摘要

A computer system have: a plurality of servers; a shared storage system for storing data shared by the servers; and a management server, wherein each of the plurality of servers includes: one or more non-volatile memories for storing part of the data stored in the shared storage system; first access history information storing access status of data stored in the non-volatile memories; storage location information storing correspondence between the data stored in the non-volatile memories and the data stored in the shared storage system; and a first management unit for reading and writing data from and to the non-volatile memories, and wherein the management server includes: second access history information of an aggregation of the first access history information acquired from each of the servers; and a second management unit for determining data to be allocated to the non-volatile memories based on the second access history information.
