The Cisco Nexus® V9P and V9P-3 FPGA Application SmartNIC is an FPGA (Field Programmable Gate Array) based network application card, optimized for low latency and high density.
The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters are equipped with a powerful 16nm Xilinx Virtex UltraScale Plus (VU9P) FPGA with 2.5M logic cells, into a compact, half-height, half-length, PCIe 16x form factor.
An extensive memory hierarchy for complex, memory-intensive applications.
The Xilinx VU9P FPGA features 75Mbit of block RAM and 270Mbit of UltraRAM on chip. The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters are also equipped with an additional 9GB of DDR4 DRAM on the board for high throughput access. The DRAM is accessible via a 72-bit-wide bus for maximum performance.
The Cisco Nexus V9P-3 FPGA Application SmartNIC model performs at a higher speed reducing the compile time by 40% over the V9P model compile times, that reduces project build time while increasing network uptime. The improved V9P-3 model logic performance and the faster clocked FPGA helps to eliminate any timing issues and can be programmed to reduce network latency to create a better user experience.
Dual QSFP-DD ports provide up to 400Gbps of full duplex connectivity.
The dual QSFP-DD ports offer high-speed 4x40GbE or 2x200GbE connectivity. Using QSFP-DD breakout cables expands the connectivity to 16x10GbE/25GbE4 connections. This high-density connectivity enables a range of high-performance, directly connected network applications, bypassing the need for traditional switching and multiplexing requirements.
Cisco is a specialist in low-latency, high-performance FPGA IP cores.
We provide you the same high-speed, low-latency IP blocks used in our market leading products, including:
● 10GbE PCS/MAC with ultra-low-latency performance
● Low-latency, high-throughput PCIe DMA engine
● Timing, signaling, and register interfaces, including I2C
● Packet field extractor and frame multiplexer (with source code)
● Asynchronous FIFO and CDC modules (with source code)
Several example designs are also provided to help get design work started and completed quickly.
A standard Linux driver as well as transparent TCP and UDP acceleration and low-level packet access.
The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters function out of the box as a high-performance network adapter. The entire Cisco Nexus SmartNIC software library is available, including the ExaSOCK sockets application acceleration system and the libexanic direct user-space access API. Libexanic provides easy support for low-latency packet TX/RX, managing the FPGA state (through register access), and low-latency TCP/UDP delegated sending of operations for hybrid hardware/software applications. The Cisco Nexus V9P and V9P-3 FPGA Application SmartNIC adapters also support fast and easy firmware updates (without requiring reboots) and vital statistics monitoring (temperatures, light levels, etc.).
