Intel OCP 3.0 - 10/25 Gigabit SFP28 x 4 Ethernet Network Adapter

The Intel E810XXVDA4OCPV3 is a server-grade network adapter that brings four SFP28 ports to your OCP 3.0 slot, each able to run at 10 or 25 Gigabit Ethernet. It is built around the proven Intel Ethernet E810 controller, so it delivers the kind of low latency, high throughput, and efficient processing that modern data centers expect.

With a PCIe 4.0 interface, the card moves data quickly between the network and the host server, which helps applications such as virtual machines, storage clusters, and high-traffic web services stay responsive under load. Technologies like RDMA over Converged Ethernet (iWARP and RoCEv2) let storage and messaging workloads bypass the CPU for direct memory access, reducing both latency and processor overhead.

Virtualization features are baked in. Single Root I/O Virtualization (SR-IOV) and Virtual Machine Device Queues allow you to assign network resources directly to individual virtual machines, giving each one a predictable slice of bandwidth. On-chip quality of service tools add another layer of traffic management, letting administrators set priorities for critical streams.

The adapter fits naturally in cloud platforms, enterprise server farms, and telecom edge deployments where density and efficiency matter. It works with both copper and fiber cabling, so you can slide it into existing racks or new builds without re-cabling the whole row. If you are upgrading a legacy 10 GbE environment or rolling out new 25 GbE links, this card offers a straightforward path to higher speeds without sacrificing stability.
