PROBLEM TO BE SOLVED: To preferentially perform transmission/reception processing of a data transfer command to a higher priority OS by restricting an IOPS and an MBPS when using an HBA from each OS to a prescribed threshold value when the plurality of OSs physically uses the same HBA. SOLUTION: In this computer system, OSs 111, 121 include HBA drivers 113, 123 respectively for controlling the HBA 140, The HBA driver has: a means relaying a command for data transfer issued to a storage device from the OS, and calculating transmission/reception performance of the data transfer command to a logical volume of the storage device or the HBA; and a means deterring execution exceeding prescribed performance of data transfer command transmission/reception.
