Link™ NT40E3 SmartNIC

4x1G/10G

Data Sheet

Use cutting-edge network SmartNIC technology to add real-time line-rate performance to your application. The Link™ NT40E3 SmartNIC provides full packet capture and analysis of network data at 40 Gbps with zero packet loss. The SmartNIC can capture all frames, including erroneous frames normally discarded by standard NICs. The SmartNIC can also be used for in-line application acceleration.

The Napatech SmartNIC allows you to merge data from ports into a single, time-ordered analysis stream. It supports 1-128 packet streams using intelligent hardware flow distribution to allow your application to scale to higher packet rates with no packet loss. The SmartNIC will distribute packets based on flow or on e.g. L3/L4 filter criteria. The 4 GB DDR3 RAM buffer allows buffering packets on the SmartNIC to prevent packet loss during peak server loads. Packets are hardware time-stamped when they arrive at the network ports, ensuring that the time stamp is always reliable. The SmartNIC also comes in a NEBS level 3 compliant variant.
