    • 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.
    • 用于优化受限系统内网络数据流的方法,装置和软件。 这些方法使数据能够在多插槽服务器平台中的PCIe卡之间传输,每个平台包括具有InfiniBand(IB)HCA和远程插座的本地插座。 从平台传出的数据通过代理的数据路径从PCIe卡传输到平台的IB HCA。 如果将目的地的PCIe卡安装在本地套接字中,或者如果目的地的PCIe卡安装在远程插座中,则通过代理的数据路径,平台上接收的数据可以采用直接PCIe对等(P2P)传输。 从本地插座的PCIe卡到平台的IB HCA的出站传输可以选择性地使用用于更大数据传输的代理数据路径或用于较小数据传输的直接P2P数据路径传输。 该软件配置为以对生成和接收数据的软件应用程序透明的方式支持本地本地,远程本地,本地远程和远程数据传输。
