fbC2CGg5 Capture Card

Dual Port QSFP28 Ethernet Capture Card

The Silicom fbC2CGg5 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 fbC2CGg5 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.

Capture Card fbC2CGg5

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 fbC2CGg5 uses a single-slot x16 lane PCIe solution. The card is prepared for inter-card connection and for second-slot connectivity for double PCIe bandwidth to the host system. NUMA specific memory allocation allows for effective traffic management and load balancing in NUMA environments.
