NT200A02 SmartNIC
with Link-Virtualization™ Software


The NT200A02 SmartNIC is a full-height, half-length QSFP28 PCIe card. By taking advantage of the programmability in the FPGA, the NT200A02 can be reconfigured to support specific SmartNIC functionality, to add new features, and to extend its capacity to continually accommodate data growth and changing industry standards.

Full Open vSwitch (OVS) offload
The NT200A02 with Link-Virtualization™ software provides a hardware-based solution for full Open vSwitch (OVS) offload – significantly increasing performance while reducing CPU consumption.

Link-Virtualization™ supports a broad range of applications and use cases and can quickly be qualified and deployed to monetize virtualized applications. This way, expensive server resources can focus on revenue generating virtual functions rather than data delivery.

Hardware Offload
Some data processing tasks, such as encryption and compression, may require a significant amount of CPU cores when performed in software. By offloading these functions to the NT200A02, performance is significantly increased by freeing up CPU cores to focus on revenue generating virtual functions.

Virtual Machine monitoring
Napatech’s VM-to-VM monitoring solution provides insight into both North-South as well as East-West traffic in the server without consuming CPU cores.

As the NT200A02 sees all data, it is possible to replicate traffic in hardware and send the OVS mirror traffic to either a virtual appliance or an external analytics solution – without consuming CPU cores.

NT200A02 is also available in a passive cooling (NEBS) variant

NT200A02-SCC SmartNIC

NT200A02-NEBS SmartNIC

To generate and control the airflow, the Napatech design contains a blower that takes in air from the top and bottom of the SmartNIC, thereby doubling the amount of air and ensuring superior cooling.


  • Durable design for extended real-life operation
  • Free choice of server platform
  • Reduced noise and power-consumption as server-fans can run at minimum speed
  • Freedom to pack unlimited FPGA SmartNICs into a standard server


  • No airflow dependency to server
  • Well-defined cooling of all critical components
  • Guaranteed device hot spot temperatures
  • Maximized airflow, ensuring optimal thermal performance
  • Dissipated energy exhaled outside server through front plate cutouts
  • Significant reduction in temperature drop between FPGA die and heat sink surface
  • Mechanical stiffener enabling higher screw torque for fastening heatsink to the PCB


Napatech upholds the highest quality, environmental and safety standards, and complies with all applicable regulations across regions. This helps our customers to realize a seamless integration without delays – and ensures error-free operation throughout the product life cycle.

Ethernet Front Port Compliance

The SmartNIC design maximizes mechanical and electrical front port margin, securing trouble-free operation with the optical or electrical modules of the customer’s choice.

The thermal design is validated dissipating the maximum power level as standardized for the given form factor. Margin on the data interface has been optimized tuning the equalization parameters of the transceivers hosting the front port channel, maximizing EYE margin to the relevant standard.

EMC Compliance

All Napatech designs have passed EMC compliance testing for major regions, including Europe and North America. By ensuring compliance as an integral part of the design, the risk of delays is eliminated. Moreover, the EMC testing has been performed in a mainstream server, potentially directly applicable to the use case.

Environmental Compliance

The end product (server + installed SmartNIC) must adhere to regional environmental legislation. To enable trouble-free server integration, Napatech SmartNICs are manufactured using only materials that fully comply with the current RoHS, REACH and proprietary Tier 1 legislation.

Full compliance from early inception eliminates the risk delays and product withdrawal due to authority intervention.

Event Handling & System Monitoring

In order for the SmartNIC to become an integral part of the server environment and maximize uptime, it needs to monitor and expose key performance metrics to the application during operation. Napatech SmartNICs monitor the following metrics:

  • Blower speed
  • Hot spot temperatures
  • Key supply voltages and currents
  • PCI protocol events
  • General system events

PCI Compliance

With the PCI interface on the SmartNIC dictated by the server plane, the hardware maximizes mechanical and electrical PCI margin, ensuring trouble-free operation in the server and server slot(s) of the customer’s choice. All designs have passed relevant PCI-SIG tests and have been adopted on the PCI-SIG integrators list.

Safety Compliance

To enable trouble-free server integration, Napatech SmartNICs are fully compliant with all applicable safety standards.

By ensuring safety compliance as an integral part of the SmartNIC design, the risk of delays is eliminated. Compliance testing is performed in a mainstream server, potentially directly applicable to the use case.

Conflict Minerals Compliance

To ensure quick and trouble-free server integration, Napatech SmartNICs are manufactured using only materials that fully comply with the relevant Conflict Mineral Legislation. For US based SmartNIC integrators, this facilitates submission of the mandatory Conflict Mineral report to SEC.

Shock & Vibration Robustness

Many server environments expose the SmartNIC to substantial shock and vibration, predominantly during the transportation phase. To ensure trouble-free server integration and operational robustness throughout the product life cycle, validated design aspects include:

  • Cooling enclosure for superior mechanical stiffness
  • Key exposed components are under-filled (glued) to the PCB
  • Shock robustness validated against JESD22-B110A
  • Vibration robustness validated against ASTM D4169-09

Used across industries

Telecom operators and Cloud-based data centers

Break the cost/performance barrier when upgrading to 25G.
With the increasing number of telecom carriers and CSPs migrating to 25G solutions, the need to continually upgrade network performance is growing.

Cloud-based data center network architectures, 5G/edge computing and the Internet of Things (IOT) are driving an incredible scale in bandwidth, number of users, and network flows. These factors are driving the explosive growth in the 25GbE server-class Ethernet adapter market with programmable SmartNICs offering the highest CAGR in all segments in the Ethernet NIC market

The Napatech NT200A02 SmartNICs deliver complete platforms to address numerous demanding networking and security workloads including hardware offloladed virtual switching to accelerate NFV, and 4G/5G mobile applications This flexible solution save rack space and reduce the overall solution cost by offloading virtual switching workloads returning valuable CPU cycles to the general purpose CPU for application processing.

Cyber security

Detect Advanced Persistent Threats (APT) and other breaches to your network at – no activity goes unnoticed.
Across industries, cyber assaults are accumulating at alarming rates. Hackers are constantly refining their tactics and repeatedly circumventing static defenses.

To identify any suspicious activity on your network, you need full visibility at all times. Even a marginal fraction of information lost can potentially compromise the safety of your business. Who has been on your network, what have they done, and when exactly did they do it? A myriad of intelligent security solutions are available to help you answer these questions – but to deliver the needed insights, they need fully reliable data. And with network speeds advancing to 25G, the challenge of attaining reliable data is firmly growing.
