01PE767 Lenovo ThinkSystem Broadcom 57414 10/25GbE SFP28 2-port PCIe Ethernet Adapter

Lenovo spare 01PE767 corresponds to the ThinkSystem Broadcom 57414 10/25GbE SFP28 2-port PCIe Ethernet Adapter, option 4XC7A08238. Feature code B5T0 identifies it in most systems, and some servers use BK1H. The card brings TruFlow flow processing, RoCE and virtualization offloads to a pair of SFP28 ports.

Two SFP28 cages accept a transceiver, a direct-attach copper cable or an active optical cable. The ports connect to 10 Gb or 25 Gb switches, and a 4:1 breakout cable shares one 100 Gb switch port. The BCM57414 controller supports jumbo frames up to 9600 bytes, link aggregation and forward error correction. Packet throughput peaks at a maximum of 30 million packets per second on this controller.

Host connectivity is PCIe 3.0 x8, and the card ships with a full-height 3U bracket attached plus a low-profile 2U bracket. Broadcom BroadSAFE technology provides a silicon root of trust for firmware, and RoCEv2 with Data Center Bridging is supported. SR-IOV exposes 128 virtual functions, and NIC partitioning reaches 16 physical functions. The board is 167 mm long and 63 mm high, and it runs at 0 to 55 degrees C. Relative humidity can range from 5 to 95 percent as long as it does not condense. Dual-rate 10G/25G SR transceivers run at 25 Gb/s only on this PCIe model, and 10 Gb and 25 Gb optics cannot be mixed.

Compatible servers include ThinkSystem SR630 V3 (7D72, 7D73), SR650 V3 (7D75, 7D76) and SR665 V3 (7D9B, 7D9A). The older SR630 (7X01, 7X02) and SR650 (7X05, 7X06) also take it, and the OCP version, 4XC7A08237, shares the family.
