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.

Abstract: According to an embodiment, a computer program product has a computer readable medium including programmed instructions. The instructions, when executed by a computer, cause the computer to function as a first rendering unit, an input control unit, a first processing unit, a second processing unit, and a second rendering unit. The first rendering unit is configured to render a first chart from first visualization object data. The input control unit is configured to receive an operation input to the first chart. The first processing unit is configured to update the first visualization object data based on the operation input. The second processing unit is configured to, when second visualization object data is updated in a manner linked to processing performed by the first processing unit, update the second visualization object data. The second rendering unit is configured to render a second chart from the second visualization object data.
