E810XXVDA4 Intel E810-XXVDA4 25G SFP28 PCIe 4.0 x16 Ethernet Network Card

High-Performance PCIe 4.0 Ethernet Adapter delivering quad-port 25GbE connectivity with the E810XXVDA4

The E810XXVDA4 is a PCIe 4.0 x16 plug-in network interface card engineered around the Intel Ethernet Controller E810-CAM1 to provide deterministic, high-throughput Ethernet for modern server and storage nodes. With 4 x SFP28 ports supporting 1/10/25GbE speed profiles, the E810XXVDA4 is designed for dense top-of-rack uplinks, leaf-spine fabrics, and high-availability host networking where predictable latency and line-rate packet processing are operational requirements.

Architecturally, the E810XXVDA4 aligns with virtualization-first CPU platforms by accelerating data-plane functions through SR-IOV and encapsulation offloads such as NVGRE and Geneve, reducing host CPU cycles consumed by overlay networking. The PCIe 4.0 x16 interface sustains multi-port throughput under east-west traffic, while RDMA capabilities (RoCE v2 and iWARP) enable low-latency transport for storage and HPC fabrics without compromising multi-tenant isolation. IEEE 1588 Precision Time Protocol support extends the E810XXVDA4 into time-sensitive deployments requiring synchronized packet timestamps across distributed systems.

Why Choose the E810XXVDA4?

The E810XXVDA4 delivers a balanced density-to-performance profile by combining 4 x 25GbE ports, PCIe 4.0 bandwidth, and enterprise offload features in a single adapter, enabling scalable host networking designs with fewer cards per node. For infrastructure teams standardizing on SFP28 optics and predictable fabric behavior, the E810XXVDA4 supports repeatable rollouts across virtualization clusters, storage targets, and latency-sensitive edge servers.

Intel designs the E810 family with a focus on stable drivers, long lifecycle availability, and interoperability with data centre standards, supporting controlled change management and consistent operational tooling in enterprise environments.

Key Applications:

• Virtualization and SR-IOV-enabled VM networking
• Container platforms with overlay offloads
• RDMA storage fabrics and NVMe-oF transport
• HPC cluster interconnect and low-latency Ethernet
• Time-synchronized networks using IEEE 1588 PTP
