Abstract

A network interface card including a printed circuit board is provided. First and second connectors may be coupled with the printed circuit board. A plurality of ethernet communication links form at least a portion of a coupling between the first and second connectors, wherein the first connector is configured to receive a third connector associated with a midplane. A chip may be coupled with the printed circuit board wherein the plurality of ethernet communication links couple the first connector with the chip. A second communication link may also be provided which couples the chip and the second connector. In accordance with one embodiment of the present invention the chip consolidates data received through the first connector for distribution of the data to the second connector. In a particular embodiment, the chip may include a hub chip. In accordance with another aspect of the present invention, the chip may include a switch chip.

Claims
