7ZT7A00549 Lenovo ThinkSystem 10Gb 4-Port Base-T LOM

7ZT7A00549 (feature code AUKM) is the ThinkSystem 10Gb 4-port Base-T LOM, a LAN-on-motherboard adapter card that adds four RJ45 10GBASE-T ports to the server. The network silicon is the Intel Ethernet Connection X722, which is built into the Intel C624 chipset, so the card itself carries connectors and no separate controller.

Each port links at 10Gb or 1Gb Ethernet; 100Mb and 10Mb are not supported. At 10 Gbps the controller adds VXLAN, NVGRE and GENEVE offloads, up to 128 VMDq virtual machines, SR-IOV with 4 physical and 128 virtual functions, and iWARP RDMA. Jumbo frames reach 9728 bytes, and VLAN tagging covers up to 4096 tags.

For management, NC-SI connects the XClarity Controller to the network through port 1 only, and Wake on LAN also works on the first port only. UEFI and legacy PXE boot are available, and the card can act as an iSCSI software initiator. Ports are numbered from Port 1 at the top, the end furthest from the edge connector.

A built-in auto-detect feature means an installed LOM can be replaced by a different one, for example a 1Gb card by this 10Gb card, and the network interface reconfigures itself at boot. 10Gb LOM adapters can be teamed with the Intel X710 and other 10Gb adapters using adapter fault tolerance, switch fault tolerance, adaptive load balancing, VM load balancing or IEEE 802.3ad link aggregation.

The 4-port Base-T LOM is supported in the ThinkSystem SR630, SR650, SR850, SR850P, SR860 and SR950. The two-port Base-T version is 7ZT7A00548 (AUKL), built on the same X722 controller.
