Lenovo ThinkSystem Intel E810-DA2 10/25GbE SFP28 2-Port OCP Ethernet Adapter

Intel's E810 controller powers the Lenovo ThinkSystem Intel E810-DA2 10/25GbE SFP28 2-Port OCP Ethernet Adapter, part number 4XC7A08294. It provides two SFP28 ports rated at 10/25GbE in an OCP 3.0 module.

Two features guide the buying decision. First, the OCP 3.0 form means the card fits only a server with an OCP slot. Second, the E810 controller is the choice when your platform standard is Intel networking for this speed class, since drivers and firmware follow Intel's family.

Dual-speed SFP28 ports let one adapter connect to either 10GbE or 25GbE switches. Two ports cover redundancy or separate networks. SFP28 optics and direct attach cables are sourced separately, so check which your switch accepts.

The DA2 in the name denotes the two-port layout; verify the port count against your cabling plan when ordering.

The 4XC7A08294 is offered new and refurbished, with 1 year or 3 years of warranty on both. No used unit is listed. Send your quantity and the server model with your request for pricing.
