Abstract:
A sideband PCI Express (PCIe) packet initiator in a distributed PCIe switch fabric verifies a PCIe connection between a host device and a PCIe endpoint device without having to power on the host device. The packet initiator assembles a PCIe test packet that acts as a ping for testing reachability of the endpoint device, from the perspective of the host device. The test packet may also verify configurations and settings of the path to the endpoint device. The distributed switch fabric is configured to compare completion data with expected results to verify the PCIe connection, without having to boot the host device.
