00YK535 Lenovo ThinkSystem Broadcom 57416 10GBASE-T 2-Port PCIe Ethernet Adapter

Spare part 00YK535 is the ThinkSystem Broadcom 57416 10GBASE-T 2-Port PCIe Ethernet Adapter, which Lenovo lists as option 7ZT7A00496 with feature code AUKP. The card is a dual-port copper network adapter that follows the IEEE 802.3an standard for 10GBASE-T and also supports 1000BASE-T under IEEE 802.3ab.

Two RJ45 connectors share one BCM57416 controller, which presents a dual-channel 10 Gbps Ethernet interface to the host. Copper links run over UTP Category 7 or 6a cabling up to 100 m, or over Category 6 cabling up to 55 m. The controller handles IPv4 and IPv6 traffic and includes the Broadcom TruFlow flow processing engine.

The host interface is PCI Express 3.0 x8 on a low-profile card, with a full-height 3U bracket attached and a 2U bracket included. Virtualization support covers NIC partitioning with 16 physical functions, SR-IOV with up to 128 virtual functions, and VXLAN, NVGRE, Geneve and GRE encapsulation. RDMA over Converged Ethernet, Data Center Bridging and DPDK are supported, and network boot works through PXE and UEFI. The board measures 168 mm long, 69 mm wide and 15 mm high without its bracket. Storage conditions run from -40 to 65 degrees C at 5 to 95 percent non-condensing humidity.

Servers that accept 00YK535 include ThinkSystem SR630 V3 (7D72, 7D73), SR650 V3 (7D75, 7D76) and ST250 V3 (7DCF, 7DCE). Earlier SR630 (7X01, 7X02) and SR650 (7X05, 7X06) models are supported as well, alongside the OCP 3.0 sibling 4XC7A08236 and the ML2 sibling 7ZT7A00497.
