1. A peripheral component interface express (PCIe) switch working mode updating method, applied to a controller, wherein the PCIe switch working mode updating method comprises:
determining a required switch firmware version of a system according to system configuration information;
determining a current switch firmware version according to a current port definition state of a PCIe switch;
determining, according to the required switch firmware version and the current switch firmware version, whether a switch port reallocation operation needs to be executed; and
in response to the switch port reallocation operation needing to be executed, sending, to the PCIe switch, a data file corresponding to the required switch firmware version, so that the PCIe switch updates a working mode according to the data file.
