E810XXVDA2OCP3G Intel E810-XXVDA2 25G SFP28 PCIe 4.0 x16 Ethernet Network Card

High-Performance OCP 3.0 Server NIC delivering 10/25GbE low-latency Ethernet with the E810XXVDA2OCP3G

The E810XXVDA2OCP3G is an Intel Ethernet 800 Series server network adapter engineered for deterministic 10/25GbE connectivity in modern virtualized and bare-metal racks. By combining dual SFP28 interfaces with hardware offloads, the E810XXVDA2OCP3G enables predictable east-west traffic behavior and efficient CPU utilization for cloud, storage, and HPC clusters.

Built on a PCIe 4.0 x8 electrical interface in a x16 physical connector, the E810XXVDA2OCP3G is optimized for high-throughput packet processing and low-latency transport while keeping platform lane consumption efficient. RDMA capabilities via RoCE v2 and iWARP align the adapter with latency-sensitive MPI-style workflows and NVMe-over-fabrics adjacent designs, while iSCSI and NFS offload support improves storage networking efficiency. For multi-tenant architectures, SR-IOV, VMDq, and Intel VT-c help isolate workloads and scale virtual interfaces without excessive host overhead. IEEE 1588v2 PTP timing support strengthens the E810XXVDA2OCP3G for time-aware environments where microsecond-level synchronization matters.

Why Choose the E810XXVDA2OCP3G?

The E810XXVDA2OCP3G provides a balanced density-to-performance profile for 1/10/25GbE fabrics, delivering enterprise-class reliability and consistent latency under mixed traffic. Its offload and virtualization feature set supports repeatable deployment patterns across clusters, enabling scalable network segmentation, predictable QoS planning, and straightforward integration into standardized server builds.

Intel designs the Ethernet 800 Series around stable driver ecosystems, long lifecycle support, and data center interoperability. The architecture focuses on standards-based Ethernet, robust offload pipelines, and validation for continuous operation in demanding enterprise and service-provider environments.

Key Applications:

• Cloud virtualization and SR-IOV tenant networking
• HPC low-latency Ethernet with RDMA
• RoCE v2 and iWARP RDMA fabrics
• Storage networking with iSCSI/NFS offloads
• Time synchronization using IEEE 1588v2 PTP
