Intel E810 25 Gbps SFP28 OCP 3.0 Adapter

This Intel E810 network adapter delivers four 25 Gbps SFP28 ports in an OCP NIC 3.0 small form factor. It connects through a PCI Express 4.0 x16 interface and supports both RDMA iWARP and RoCEv2 for low-latency data movement. The card targets servers and high-performance workstations needing dense 25 Gigabit Ethernet connectivity.

Verify PCIe 4.0 x16 slot

Confirm the host system provides a PCI Express 4.0 x16 slot that can supply the required lane width for full throughput. Ensure SFP28 transceivers and matching cables are sourced separately, as the adapter ships without optics. Check that the chassis accommodates the OCP 3.0 small form factor dimensions and airflow path.

Replaces older 10 Gbps or single-port 25 Gbps NICs

The four-port 25 Gbps design consolidates multiple legacy 10 Gbps adapters into a single slot, reducing cabling and power draw. Upgrading is worthwhile when workloads demand RDMA over iWARP or RoCEv2 and the platform supports PCIe 4.0 x16. It is not for builds limited to PCIe 3.0, lacking OCP 3.0 bays, or needing only a single 25 Gbps link.

Questions about this item

Does the Intel E810XXVDA4OCP3G include SFP28 transceivers or cables in the box?

The adapter ships without SFP28 transceivers or cables; compatible 25 Gbps SFP28 modules and direct-attach cables must be purchased separately.

Which PCIe generation and lane width does the E810XXVDA4OCP3G use?

The card plugs into a PCIe 4.0 x16 slot, delivering 16 GT/s per lane for full 25 Gbps throughput.

What real-world throughput can I expect from the 25 Gbps rating once the card is installed?

In a PCIe 4.0 x16 system the adapter sustains close to 25 Gbps line rate, limited mainly by the switch port and cable quality.
