  • Publication number: 20120250496
    Abstract: A load distribution of controllers is made possible in a combination of a switch and a controller which do not have a load distribution function independently, and in a combination of the switch and the controller that do not have a compatibility in the load distribution function due to a difference of makers. Specifically, in a system which controls a data flow flowing through the network by dynamically setting a delivery route of a packet to switches in the network by the controllers such as a server, the master controller is determined to the switch while notifying a connection from the switch to the plurality of controllers, by a proxy provided between the switch and the controller, and an inquiry message from the switch is transferred only to the master controller. A route data registration message is transmitted to the proxy from the master controller in response to the inquiry message from the switch.

  • Patent number: 8145927
    Abstract: In a computer room including information processing devices and air conditioners, power saving of the computer room by means of optimization of workload allocation to the information processing devices is achieved in a short time. There, a coefficient of air conditioner performance with respect to the information processing device (device-specific COP) is calculated for each air conditioner. Further, a device-associated power consumption expression representing a total of device power and air conditioner power is created for each information processing device. Also, power consumption of the entire computer room is calculated from the device-associated power consumption expression of the information processing devices. Also, workload allocation is determined by using power saving performance evaluation indexes based on the device-associated power consumption expression of the information processing devices.

  • Patent number: 8049397
    Abstract: There are some cases where cracks occur at a plurality of areas on an external electrode when a displacement quantity of a laminated piezoelectric element is large. In such cases, there is a possibility of a voltage not being applied to a portion of the laminated structure due to the cracks caused by a long time drive to cause a reduction in the displacement quantity. A low rigidity layer is arranged on the laminated structure to form a plurality of portions divided by the low rigidity layer in a laminating direction. Each portion is provided with power feeding members on the anode side and the cathode side. Thus, a voltage can be stably supplied to each internal electrode.
