  • Publication number: 20130055257
    Abstract: A gateway apparatus relays communication between first and second servers provided in a data center and an external communication apparatus located outside the data center. A control apparatus obtains an observation result obtained by observing a communication amount being an amount of data transmitted/received per unit time for each of virtual machines operating in the first and second servers in association with a transmission source and a destination of the data. When the first number of hops is smaller than the second number of hops, the control apparatus controls an arrangement of the virtual machines so that the virtual machine whose communication amount with the external communication apparatus is larger is more likely to be placated in the first server.

  • Patent number: 7789532
    Abstract: A light source device includes a light source lamp, a rotary plate, a heat absorbing portion, and a filter mounting member. The light source lamp emits illumination light. The rotary plate includes multiple opening portions that are selectively disposed in the illumination light path of the light source lamp. A reflective filter that reflects light of a wavelength that acts a heat source in illumination light is provided in one of the multiple opening portions of the rotary plate. The heat absorbing portion absorbs heat included in reflected light reflected by the reflective filter in the opening portion. The filter mounting member disposes the reflective filter in the opening portion at a predetermined angle of inclination to the optical axis of the illumination light. By disposing the inclined reflective filter in the illumination light path, reflected light reflected by the reflective filter is reflected towards the heat absorbing portion.
