Broadcom based BCM975414A NIC PCIe 3.0 x8 Dual Port 25GbE Open SFP28

The PCIe x8 Broadcom BCM57414 Dual-Port 25G SFP28 Network Adapter is a dual-port 25Gbps, PCI Express Gen3 x8 Network Interface Card that supports both SFP28/SFP+ optical modules and copper direct attach cabling. The card uses the Broadcom BCM57414 25GbE MAC controller with the integrated dual-channel 25GbE SFI transceiver. This enables low latency, a high message rate and an embedded PCIe switch and NVMe over Fabrics offloads. These intelligent remote direct memory access (RDMA) enabled adapters provide advanced application offload capabilities for high-performance computing (HPC), cloud hyperscale, and storage platforms.
