Cisco Ultra-low Latency Network Interface Card

Introducing the Cisco Ultra-low Latency Network Interface Card, a high-density NIC purpose-built for deterministic performance in data centers, financial trading floors, and HPC environments. Built around the Cisco Nexus X100 SmartNIC family, the K3P-Q variant delivers ultra-low latency, scalable throughput, and software-driven control that minimizes jitter and host CPU overhead. Designed for mission-critical workloads where every nanosecond counts, this NIC combines edge-to-core efficiency with Cisco’s proven reliability and ecosystem compatibility.

• High-density design with 2x QSFP28 ports—the Cisco X100 SmartNIC K3P-Q supports a compact footprint that enables dense deployments and simplified cabling. This configuration is ideal for expanding your network fabric without sacrificing slot efficiency, making it possible to scale out latency-sensitive environments with fewer PCIe cards.
• Ultra-low latency performance—software trigger-to-response latencies as low as 596 nanoseconds position this NIC as a benchmark for deterministic networking. For latency-focused applications such as high-frequency trading, real-time analytics, and low-latency virtualization, every cycle counts.
• 8-channel high-density configuration—the 2x QSFP28 ports can be deployed in a high-density 8-channel setup, enabling granular traffic steering and parallel processing paths. This capability supports precise bandwidth allocation and reduced queuing delay across multiple lanes.
• Optimized for Cisco Nexus X100 SmartNIC ecosystem—the K3P-Q is engineered to work seamlessly with Cisco’s Nexus X100 platform, offering hardware-assisted offloads, programmable acceleration, and software-defined controls that reduce host CPU load and improve predictability under load.
• Reliability, security, and ecosystem fit—as part of the Cisco Nexus line, this NIC is designed for enterprise-grade reliability, robust security features, and straightforward interoperability with Cisco networking gear, software telemetries, and lifecycle management tools.
