Nexus X25 2-port SFP28 SmartNIC (2-channel) KU3P FPGA The Cisco Nexus NXN-K3P-2X, K3P-S FPGA SmartNIC is specifically optimized for low-latency operation. Features software trigger-to-response latencies as low as 568ns. Users will find that this drop-in replacement NIC accelerates tick-to-trade performance to previously unachievable speeds, increasing the efficacy and profitability of software-based trading systems. The Cisco Nexus K3P-S FPGA SmartNIC provides the most powerful programmable software interface on the market. Programmability features include: ● Zero-latency cost hardware flow steering: This feature lets users steer and prefilter important traffic to the right memory and CPU core with no latency penalty. ●Cut-through receive: A feature that allows software to process packet fragments as they arrive from the wire, while packet tails are still in flight. This is especially effective for slow line speeds (for example, 1GbE). ●ExaSOCK TCP/IP acceleration: Unmodified socket applications can benefit from the speed and power of the Cisco Nexus K3P-S FPGA SmartNIC using ExaSOCK. ExaSOCK is an in-place TCP/IP socket acceleration system. ExaSOCK's Extension API allows it to seamlessly interoperate with the Cisco Nexus K3P-S FPGA SmartNIC transmit preloading feature. ●Preloaded packet transmit: The Cisco Nexus K3P-S FPGA SmartNIC allows users to preload transmit frames, saving 60ns from the transmit path. The Cisco Nexus K3P-S FPGA SmartNIC features enlarged packet transmit buffers allowing many more frames to be preloaded, leading to more versatile transmission choices. ●High-resolution timestamps: 4ns timestamps are applied to every received packet and the most recently transmitted packet. The Cisco Nexus K3P-S 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-S FPGA SmartNIC will support 25G Ethernet speeds through a firmware update. This will reduce capital expenditure on difficult infrastructure upgrades. The Cisco Nexus K3P-S FPGA SmartNIC is built using the latest generation Xilinx Ultrascale+ FPGA. It is a compact adapter in a low-profile form-factor. Users can benefit from the pure FPGA design by offloading critical network processing functions directly into the NIC using our fast and powerful Firmware Development Kit (FDK), while maintaining the ease of use and administration of a production-grade network adapter.
