August 27, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- Quanta Computer Inc. (Tao Yuan Shien, TW) has been issued patent number 8806252, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Chou, Le-Sheng (Zhongli, TW); Shih, Sz-Chin (New Taipei, TW).

This patent was filed on April 18, 2012 and was published online on August 12, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The invention relates in general to a server cluster and a control mechanism thereof.

"The blade server is optimized with modular design to reduce the physical space and energy to a minimum and further simplify the server configuration. However, when abnormal disconnection occurs to the network of the data center in which the blade server is located, the operation of the blade server relies on manual operation, or, the administrator can turn off the power of the blade server with a remote-end management server. However, the aforementioned mechanism cannot instantly respond to the disconnection state of the network, and is thus unable to save power for the blade server."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "The invention is directed to a server cluster and a control mechanism thereof. A network connection state at the server node is detected, and the power of the server node is automatically turned on and shut down with a logic circuit, so that automatic control is achieved for saving power.

"According to a first aspect of the present invention, a server cluster including a network switch and multiple server nodes is provided. The network switch is connected to an external network. Each server node includes a network port, a network chip and a control unit. The network port is connected to the network switch via a cable. The network chip detects the cable to obtain a connection state with the external network at the server node after the network switch is started, and accordingly outputs a connection state signal. The control unit turns on or shuts down the server node according to the connection state signal and an on/off state of the server node.

"According to a second first aspect of the present invention, a control mechanism of a server cluster is provided. The server cluster includes a network switch and multiple server nodes. Each server node includes a network port, a network chip and a control unit. The network switch is connected to an external network. The network port is connected to the network switch via a cable. The control mechanism includes the following steps. A network switch is started. A network chip is used for detecting the cable to obtain a connection state with an external network at a server node and accordingly outputting a connection state signal. The control unit is used for turning on or shutting down the server node according to the connection state signal and an on/off state of the server node.

"The above and other aspects of the invention will become better understood with regard to the following detailed description of the preferred but non-limiting embodiment(s). The following description is made with reference to the accompanying drawings."
