Abstract
According to one embodiment, a switch system includes a peripheral component interconnect express (PCIe) interface block coupled to a plurality of PCIe ports, the plurality of PCIe ports being adapted for coupling to one or more external PCIe devices, wherein the PCIe interface block includes logic adapted for providing direct memory access (DMA) for each PCIe lane thereof, multiple switched Ethernet ports adapted for coupling to one or more external Ethernet devices, switching logic adapted for switching between the multiple switched Ethernet ports and the plurality of PCIe ports, and a local processor coupled to the PCIe interface block. The external host includes a pass-through PCIe adaptor coupled to the switch system via a PCIe port. Other systems, computer program products, and methods are described according to more embodiments.
