Lenovo ThinkSystem Intel E810-DA4 10/25Gb 4-Port SFP28 PCIe Ethernet Adapter

Four SFP28 ports rated at 10/25Gb on one Intel E810 controller are what the Lenovo ThinkSystem Intel E810-DA4 10/25Gb 4-Port SFP28 PCIe Ethernet Adapter, part number 4XC7A80267, delivers. It installs in a standard PCIe slot.

The four-port layout fits hosts that need many fast links in one slot: separate production, storage and backup networks, or two redundant pairs going to different switches. Ports run at 10Gb or 25Gb depending on the switch side, so the card works while a network is being upgraded.

The DA4 name signals four ports, while the DA2 version has two and its own part number. Confirm the count against your cabling plan before ordering.

SFP28 cages take SFP28 optics or direct attach cables, bought separately. Modules are not included. Match the connector type and speed your switches support.

The PCIe form is distinct from the OCP module that shares the controller. Check which slot type your server has.
