fbC2CGhh Dual Capture Card

fbC2CGhh - half height Capture Card - Dual QSFP28 port card supporting multiple Ethernet speeds, PCIe Gen3 16 lanes

General Details

fbC2CGhh – half height Dual Port Capture Card – Dual QSFP28 port card supporting multiple Ethernet speeds, PCIe Gen3 16 lanes

The Silicom fbC2CGhh Dual Capture Card offers network connectivity and capture to host memory with zero packet loss and with hardware packet processing. The 2xQSFP28 slots allow link speed support for 2x100GE/40GE/25GE, 8x10GE and 8x25GE. The fbC2CGghh card is based on cutting edge Xilinx FPGA technology in the Kintex UltraScale+ series, providing packet filtering, advanced processing, traffic management, load balancing and host offloading mechanisms.

This high performance hardware platform connects to the network using QSFP28/QSFP+/SFP28 modules and performs packet processing, while delivering a sustained throughput to host memory of up to 107 Gbps, using the standard PCIe connector with full support for standard gen3 x16. The fbC2CGghh uses a single-slot x16 lane PCIe solution, while only being half height. This makes it suitable for high performance applications with a minimal footprint. NUMA specific memory allocation allows for effective traffic management and load balancing in NUMA environments.
