Intel E810-2CQDA2 100GbE Dual-Port QSFP28 PCIe 4.0 x16 Adapter

The Intel E810-2CQDA2 is a dual-port 100 Gigabit Ethernet adapter built on Intel's E810 Ethernet controller, delivering full line-rate 200 Gbps aggregate throughput across two QSFP28 ports. Operating over a PCIe 4.0 x16 host interface, the adapter provides the bandwidth headroom required for latency-sensitive and throughput-intensive workloads in modern data centers. The E810 controller integrates Intel's Dynamic Device Personalization (DDP) technology, enabling the adapter's packet processing pipeline to be reconfigured at runtime to support specialized traffic profiles for storage, telecommunications, and cloud networking without requiring hardware replacement.

The adapter supports a comprehensive set of offload and virtualization capabilities, including RDMA over Converged Ethernet (RoCEv2), SR-IOV with up to 256 virtual functions per port, and hardware-based flow steering through Intel's Advanced Flow Director. Precision Time Protocol (PTP) and IEEE 1588 hardware timestamping are supported natively, making the adapter well suited for time-sensitive networking (TSN) and telecom workloads that require sub-microsecond synchronization. The E810-2CQDA2 also supports the DPDK and RDMA software stacks, and is compatible with the Linux kernel inbox driver (ice) as well as Intel's out-of-tree driver package.

Targeted at hyperscale storage fabrics, ORAN radio access network fronthaul/midhaul, and high-performance computing interconnects, the E810-2CQDA2 is designed for platforms requiring sustained full-duplex 100GbE per port without port-level oversubscription. The adapter conforms to the PCIe 4.0 specification with backward compatibility to PCIe 3.0 slots, broadening platform compatibility across current and prior-generation server infrastructure. Its low-profile and full-height bracket options support installation in a range of rack server form factors.

Ideal for

• NVMe-oF storage fabric connectivity providing full 100GbE line-rate access between storage servers and compute nodes with RoCEv2 offload reducing CPU overhead
• ORAN-compliant 5G fronthaul and midhaul transport requiring IEEE 1588 hardware timestamping and sub-microsecond PTP synchronization across distributed radio units
• High-density server virtualization environments leveraging SR-IOV to present up to 256 virtual functions per port directly to guest VMs with near-native throughput
• High-performance computing (HPC) cluster interconnects where MPI workloads benefit from RDMA-capable low-latency 100GbE links between compute nodes
• Network function virtualization (NFV) platforms using DPDK-accelerated packet processing for virtual firewalls, load balancers, and deep packet inspection at line rate
• Cloud service provider spine-leaf fabric uplinks where DDP reprogramming enables customized per-flow classification and traffic steering without additional hardware
