Computing architectures, platforms, and systems are provided herein. In one example, a computing system is provided. The computing system includes a management processor configured to initiate a peer-to-peer arrangement between a first peripheral component interconnect express (PCIe) device and a second PCIe device over a PCIe fabric comprising one or more PCIe switches. The peer-to-peer arrangement is established to detect data transfers from the first PCIe device directed to addresses corresponding to an address range established for the second PCIe device by a peer-to-peer management entity executed on a host processor, and redirect the data transfers over the PCIe fabric to the second PCIe device such that the data transfers are received by the second PCIe device without passing through the host processor.
