Lenovo 4XC7A95697 10GbE network card PCIe 3.0 x8 4 ports

Four-port 10 GbE adapter for servers

The Lenovo 4XC7A95697 is a quad-port 10GBASE-T network card built on the Broadcom BCM57412 controller. It plugs into a PCI Express 3.0 x8 slot and delivers up to 8000 MB/s of host bandwidth. The card targets servers and workstations that need dense 10 Gb Ethernet connectivity over twisted-pair copper cabling.

Sustained throughput on copper links

Each port negotiates 10 Gbps or 1000 Mbps over Category 6 cable up to 100 metres. The 57412 controller handles SR-IOV, VXLAN and NVGRE offloads, keeping CPU utilisation low during continuous virtualised workloads. Four independent MACs share the x8 PCIe lane budget, so aggregate throughput scales with the number of active flows rather than bursting on a single queue.

Standard half-height bracket fits most chassis

The adapter uses a standard PCIe half-height bracket, so it installs in rackmount servers, towers or workstations without a riser. Driver support is included in current Linux kernels and Windows Server releases; no proprietary firmware utility is required. Builders must verify that the host platform provides a physical x8 slot wired for at least x4 electrical lanes, otherwise the card will not enumerate.
