On this page we have answered the most frequently asked questions about our products. If you don’t find the answer here, you can write us directly, or learn more in our resources section where you can find data sheets, white papers, and much more.
Napatech SmartNICs will not drop any packets even when receiving 64 byte minimum frame size at full line rate.
Napatech SmartNICs are made for performance acceleration of network management and security applications, enabling them to stay ahead of the speed of networks in order to do their jobs. Standard NICs are made as an end point of network to provide peer-to-peer communication functionality for general user applications.
Read more in our Product Overview Data Sheet.
Napatech SmartNICs are equipped with onboard hardware acceleration features for network management and security applications with minimal impact on server platform resources. To distinguish from regular NICs, which have no (or very limited) performance acceleration features, we call our products “SmartNICs.”
For more detailed information about acceleration features, read our Feature Overview Data Sheet.
A server equipped with appropriate PCIe slots can be a server platform for Napatech SmartNICs. Supported OS are Linux, FreeBSD, and Windows. The host server resources consumed by Napatech SmartNICs are minimal, with no specific requirement for CPU performance and its memory size.
Read more in our accelerator data sheets for host interface and environmental requirements.
Yes, all Napatech SmartNICs support PCAP and there is an application note for running SNORT with Napatech SmartNICs available. The Napatech driver provides the possibility for setting up 32 virtual PCAP interfaces per accelerator.
Read more in Running Snort with 3GD which is included in the software package under application notes.
Yes, it possible to combine up to eight SmartNICs in one server, but check with a Napatech sales representative for such setup, as not all SmartNICs can be used.
Napatech SmartNICs are designed for use with Commercial Off-The-Shelf (COTS) servers, and work with any PCIe compliant server. Hint: Make sure that the length of the slot, number of lanes, and power supply matches the chosen Napatech product.

Depending on the software you use, you should order the following accelerators:
- CA: order the NAC10-2 or NAC10-4
- Symantec: order the NT4E-4T (801-0075-09-02-SY) and the 2GB memory module (802-003400-02) or the NT4E-4 (801-0074-09-02-SY)
- Oracle: order the NT4E-4T (801-0074-09-02) and the 2GB memory module (802-0034-00-02)
- Viavi (Formerly JDSU): order the 4 x 1GbE (801-0090-01-14)
If you are using different software, please contact us for further guidance.
The list of qualified pluggable modules is available via the support center. If you don’t have a login to the support center, please contact sales for more information on what SFP and SFP+ qualified modules you can use with Napatech SmartNICs.
Napatech Pandion will continue to capture and overwrite the oldest data.
Yes, Pandions can be grouped together, and a federated search can be performed across all of them.
The data from all grouped Pandions is merged in time order and returned in a single PCAP file.
Yes, captured packets are indexed using a 5-tuple, thereby accelerating searches that contain these 5-tuples.
It can be any mix.
Yes. Pandion packet timestamping can be synchronized via PTP.
One per chassis, i.e. one for Pandion 20 and one per unit for a Flex Solution.
Microsoft AD and full LDAP can be used for authentication.
NACs have the same basic properties as our SmartNICs, but support only the PCAP interface and are designed to be used with popular open source applications without any development or integration effort.
The Installation and Configuration Wizard for Linux and Windows enables you to get your PCAP application up and running in minutes.
Yes, our NACs support multiple PCAP streams and enable you to scale up to 32 PCAP applications for maximum performance.
