About the BCM957504A5041CC
BCM957504A5041CC is Broadcom's high-density NetXtreme-E quad-port 100GbE QSFP56 PCIe 4.0 x16 network adapter powered by the BCM57504 controller. Delivering up to 400Gb/s aggregate bandwidth, it is engineered for hyperscale cloud data centers, GPU computing fabrics, and high-speed NVMe-oF distributed storage clusters requiring high port density and TruFlow SDN offload.
Compatibility
The adapter requires a mechanical and electrical PCIe 4.0 x16 slot in high-performance enterprise servers. Features four QSFP56 cages supporting 100GbE, 50GbE, 40GbE, and 4x25GbE breakout cabling. Requires robust server chassis cooling fans to dissipate heat from the quad-port controller.
How to identify a genuine unit
The full-height PCIe card displays an official Broadcom label showing part number BCM957504A5041CC and BCM57504 controller branding. Four QSFP56 ports are aligned on the rear bracket. In Linux, the bnxt_en kernel driver identifies four 100G interfaces with RoCEv2 support.
Buying used
Verify that all four QSFP56 optical cages establish link cleanly under traffic load. Check thermal sensor telemetry in ethtool or vendor diagnostics to confirm the heatsink is properly mounted. Confirm that the card operates with standard Broadcom firmware.
