The Cisco Nexus NXN-K3P-8X-9GB, K3P-Q FPGA SmartNIC is a high-density SmartNIC, specifically optimized for low-latency operation. Features 2x QSFP28 ports that can be deployed in a high-density 8-channel configuration and software trigger-to-response latencies as low as 596ns. Users will find that this drop-in replacement SmartNIC accelerates tick-to-trade performance to previously unachievable speeds, increasing the efficiency and profitability of software-based trading systems. Programmability features include: Zero-latency cost hardware flow steering: This feature allows traffic filtering and steering to the right memory and CPU core with no latency penalty. Cut-through receive: A feature that lets software process packet fragments as they arrive from the wire, while packet tails are still in flight. Especially effective for slow line speeds (for example, 1GbE). The Cisco Nexus K3P-Q FPGA SmartNIC software API puts users well ahead of traditional store-and-forward SmartNIC designs to make better decisions faster. ExaSOCK TCP/IP acceleration: Unmodified socket applications benefit from the speed and power of the Cisco Nexus K3P-Q FPGA SmartNIC using ExaSOCKs in-place TCP/IP socket acceleration system. ExaSOCKs Extension API allows it to seamlessly interoperate with the Nexus K3P-Q SmartNICs transmit preloading feature. Preloaded packet transmit: The Cisco Nexus K3P-Q FPGA SmartNIC allows users to preload transmit frames, saving 60ns from the transmit path. The Cisco Nexus K3P-Q FPGA SmartNIC features enlarged packet transmit buffers allowing many more frames to be preloaded, leading to more versatile transmission choices. High-resolution timestamps: Four-nanosecond timestamps are applied to every received packet and the most recently transmitted packet. The Cisco Nexus K3P-Q FPGA SmartNIC also features out of the box support for IEEE1588 (PTP) and high-speed capture to disk using free and open-source Exact Capture software. The Cisco Nexus K3P-Q FPGA SmartNIC is a pure FPGA-based network adapter that is 25GbE ready. It will support additional Ethernet speeds through a firmware update. The Cisco Nexus K3P-Q FPGA SmartNIC is built using the latest generation Xilinx UltraScale+ FPGA. A compact, low-profile, form-factor adapter, the SmartNIC optionally ships with 9GB of DDR4 memory for custom applications. The all-FPGA design allows the user to offload critical network processing functions directly into the SmartNIC.
