Extensible computing system

The invention claims concerns connected with the server is a scale dynamic variable, the height extending and information to the rent method and device. The virtual servers renting area (VSF) structure in a structure of one distance (a grid), which is arranged on the physical and time, and according to demand logic partitioning of different structure of VSF. Each structure which an independent management control VSF. A computing grid; the VSF passive voice using firewall protection. The VSF the assignment and control of element, realized by the specified control port of the control platform, the control platform all the switch element and grid computer, a circuit device and storage element is. Each VSF inner topology structure is controlled by the control platform. Is a structure comprises a single network server or the multi-layer network server, the pixel server and database server different configuration's VSF, the un-re-changeable program physical circuit. Multi-layer VSF (e.g. network server layer, server by layer and database server layer and a on each), a according to the server on the specific load layer, and dynamic change the scale. The storage device comprises a first multiple logical solution, related connector which is connected with the calculating grid element undertake. The first, a switch element and entrust with the monitoring function or a duty, the network server, application server, database server and a on. The function of each switch element of multiple the memories with a programming, and each to define provided with a lens image with the function related company's switch element.
