Abstract: An information storage device includes a storage unit, a control unit, an allocation information storage unit, a QoS parameter storage unit, and a monitoring result storage unit. The control unit creates and manages a logical storage area using the storage area of the storage unit when a storage area allocation request is received. The allocation information storage unit stores allocation information related to logical storage areas. The QoS parameter storage unit stores quality requests expected to be satisfied for a communication for using the logical storage area. The control unit monitors the operating state and characteristics of the storage unit and the communication status, and stores the results in the monitoring result storage unit. The control unit derives internal QoS parameters to be set in the information storage device from the information stored in the allocation information storage unit, the QoS parameter storage unit, and the monitoring result storage unit.
