    摘要： Methods, apparatus, and software for optimizing network data flows within constrained systems. The methods enable data to be transferred between PCIe cards in multi-socket server platforms, each platform including a local socket having an InfiniBand (IB) HCA and a remote socket. Data to be transmitted outbound from a platform is transferred from a PCIe card to the platform's IB HCA via a proxied datapath. Data received at a platform may employ a direct PCIe peer-to-peer (P2P) transfer if the destined PCIe card is installed in the local socket or via a proxied datapath if the destined PCIe card is installed in a remote socket. Outbound transfers from a PCIe card in a local socket to the platform's IB HCA may selectively be transferred using an either a proxied data path for larger data transfers or a direct P2P datapath for smaller data transfers. The software is configured to support each of local-local, remote-local, local-remote, and remote-remote data transfers in a manner that is transparent to the software applications generating and receiving the data.

    摘要： Embodiments of the invention describe systems, apparatuses and methods that enable sharing Remote Direct Memory Access (RDMA) device hardware between a host and a peripheral device including a CPU and memory complex (alternatively referred to herein as a processor add-in card). Embodiments of the invention utilize interconnect hardware such as Peripheral Component Interconnect express (PCIe) hardware for peer-to-peer data transfers between processor add-in cards and RDMA devices. A host system may include modules or logic to map memory and registers to and/or from the RDMA device, thereby enabling I/O to be performed directly to and from user-mode applications on the processor add-in card, concurrently with host system I/O operations.
