Technical Field This application relates to the field of server technology, and in particular to network interface card (NIC) bandwidth configuration systems, methods, devices, storage media, and program products. Background Technology Open Compute Project (OCP) network interface cards (NICs) are high-performance network interface devices widely used in data centers with high network performance requirements. OCP NICs support a single primary bandwidth, two primary bandwidths, or a secondary bandwidth, but the hardware environment configured for each bandwidth differs. The inventors recognized that motherboards are typically designed with hardware environments tailored to OCP NICs with a single bandwidth configuration. This fixed hardware design cannot flexibly adapt to OCP NICs with different bandwidth requirements. Furthermore, OCP NICs with different bandwidths also differ in the number of PCIe signals required and the interface pin definitions. Therefore, it is difficult to achieve compatibility and adaptation for multiple OCP NICs with different bandwidths on the same motherboard.
