Cisco Nexus SmartNIC

Programmable ultra-low latency, high-precision time-stamping SmartNICs

Increase performance. Lower latency. Customize functionality. Nexus Smart Network Interface Cards (SmartNICs) are next-generation FPGA-based ultra-low latency and high-resolution timestamping adapters. Program your network and accelerate application offloads with Nexus SmartNICs.

Ultra-low latency programmable SmartNICs

Nexus SmartNICs are optimized for networks that require ultra-low latency, such as financial trading. Used in combination with Cisco software and tools, our SmartNICs can replace existing NICs, providing up to 10x latency performance.

All Nexus SmartNICs are designed for ultra-low latency operation.

Accelerate your applications with in-line sockets acceleration and kernel bypass technology.

High-precision hardware time-stamping and time synchronization.

Field-upgradeable SmartNICs allow customizable functionality.
