Lenovo lists 4XC7A80566 (feature code BNWM) as the ThinkSystem Broadcom 57504 10/25GbE SFP28 4-port PCIe Ethernet Adapter. It is built on the Broadcom BCM57504 four-port controller and runs at 10 or 25 Gb/s; other speeds are not supported.
The card has a PCIe 4.0 x16 host interface in a low-profile form factor and four SFP28 cages that take a transceiver, direct-attach copper cable or active optical cable. Lenovo lists jumbo frames up to 9600 bytes, link aggregation, 100 million packets per second, and forward error correction at Clause 74 and Clause 91 on 25 Gbps links. TruFlow flow processing handles VXLAN, NVGRE, Geneve and RoCE traffic.
Network boot is by PXE or UEFI; Wake-on-LAN is not supported, and iSCSI boot works only through the server UEFI, not in legacy mode.
The same controller is sold in an OCP 3.0 form factor as 4XC7A80567 (BPPW).
