<P>PROBLEM TO BE SOLVED: To provide a rack server system which reduces a risk of data loss of the rack server system during a validity test of a battery backup unit, and to provide a control method thereof. <P>SOLUTION: A rack server system establishes a communication link for communicating with a battery backup unit. The battery backup unit is connected to an electric power input port of the rack server system, and includes a plurality of battery modules connected with each other in parallel. The rack server system controls the battery backup unit so that the battery backup unit performs a validity test on a first battery module during a first period and performs a validity test on a second battery module during a second period. The first period and the second period are not overlapped with each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
