PURPOSE:To increase a stack function of an access request, by simultaneously setting access requests from each access request device, to each port which is capable of access independently, and sending them out to a storage device, holding the sequence of the access request. CONSTITUTION:To an operatint device 10 of a computer system, plural access request control devices 20-23 are connected, and to the control devices 20-23, a storage control device 30 is connected. Also, to the device 30, a storage device 40 having ports 400-403 which are capable of access independently, respectively is connected. Moreover, on the device 30, access request stack devices 300-303 corresponding to the control devices 20-23, and access request setting signal generating devices 310-313 corresponding to the ports 400-403 are provided. Subsequently, a stack 300A of the devices 300-303 and a precedence deciding logic 310A of the devices 310-313 are connected to each other, each access request is sent out to a storage device 4, holding its sequence, and a stack function of the access request is increased. |
