FPGA SmartNIC for low-latency networking

The Cisco NXN-V9P-16X-9GB is an FPGA-based SmartNIC built around a Xilinx Virtex UltraScale Plus VU9P device with 2.5M logic cells. It targets developers and infrastructure teams deploying custom packet-processing, acceleration or telemetry workloads directly on the network interface. The card occupies a single PCIe 16x slot in a low-profile, half-height, half-length form factor.

Half-height card with dual QSFP-DD cages

A compact bracket set includes both full-height and half-height brackets for flexible chassis compatibility. Two QSFP-DD cages accept 100GBASE-SR4, 100GBASE-LR4, 40GBASE-SR4, 40GBASE-LR4 modules or direct-attach breakout cables. Breakout support expands the physical connectivity to sixteen 10GbE or 25GbE lanes, enabling dense direct-attach topologies without an intermediate switch layer.

9GB DDR4 on a 72-bit bus for memory-bound workloads

Onboard memory comprises 9GB of DDR4 DRAM connected via a 72-bit-wide bus, supplemented by 75Mbit of block RAM and 270Mbit of UltraRAM inside the FPGA. This hierarchy serves applications that require high-throughput, low-latency access to large working sets such as stateful flow tables or inline analytics. Firmware upgrades and the FDK require an active Cisco SMARTnet subscription.

Questions about this item

What bandwidth does the PCIe 16x interface deliver to the FPGA?

The card uses a PCIe 16x interface to move data between the host and the Xilinx VU9P FPGA with 2.5M logic cells.

Which brackets are included for mounting in different chassis heights?

Both a full-height bracket and a low-profile half-height bracket ship in the box.

What is required to program the FPGA after the card is seated?

A Cisco SMARTnet subscription for firmware and the separate FDK (NXN-N35-FDK) are needed to enable programmability.
