Patent attributes
Systems are provided where a chassis houses an Information Handling System (IHS). The chassis includes a motherboard with one or more CPUs configured to operate as a root complex for a PCIe switch fabric that includes a plurality of PCIe devices of the IHS. The chassis also includes an I/O module providing I/O capabilities for the motherboard. The I/O module includes a network controller configured to allocate network bandwidth for use by a hardware accelerator sled installed in the chassis, unless an integrated network controller is detected as a component of a hardware accelerator baseboard installed in the hardware accelerator sled. The I/O module also includes a PCI switch configured to operate with the CPUs as the root complex of the PCIe switch fabric and further configured to operate with the hardware accelerator baseboard as the root complex of the PCIe switch fabric.
