00YK537 Lenovo ThinkSystem Broadcom 57412 25GbE SFP28 1-Port PCIe Ethernet Adapter

The ThinkSystem Broadcom 57412 25GbE SFP28 1-Port PCIe Ethernet Adapter is spare 00YK537, tied to option 7ZT7A00505 and feature code AUKS. The card carries one SFP28 cage on the Broadcom BCM57412 controller.

The cage takes a transceiver, a direct-attach copper cable or an active optical cable, and the link works with 10 Gb or 25 Gb switches. Traffic reaches the host over PCIe 3.0 x8. Jumbo frames reach 9600 bytes, and link aggregation under 802.3ad and 802.1AX, forward error correction and IEEE 1588 time sync are supported. Peak packet rate is 30 million packets per second.

TruFlow flow processing offloads traffic handling from the host, and RoCEv2 with Data Center Bridging provides remote direct memory access. Up to 128 SR-IOV virtual functions and 16 NIC-partitioned physical functions can be configured. VXLAN, NVGRE, Geneve and GRE offloads are included. The PCIe board is 167 mm long and 63 mm high. Rated operating temperature is 0 to 55 degrees C, and humidity may range from 5 to 95 percent if no condensation forms.

Installation of 00YK537 is supported in ThinkSystem ST250 (7Y45, 7Y46), SR250 (7Y52, 7Y51), SR550 (7X03, 7X04) and SR590 (7X98, 7X99) systems. The two-port Broadcom 57414 relative in the same family is 4XC7A08238, and its OCP version is 4XC7A08237.
