Description

The Intel E810-CQDA1 is a high-performance Ethernet adapter delivering up to 100 Gbps via a single QSFP28 port. Designed for modern data centers and high-performance computing, it provides versatile connectivity—with support for 100, 50, 25, or 10 GbE—over DACs, AOCs, or optical transceivers. It seamlessly plugs into a PCIe 4.0 x16 low-profile slot, ensuring maximum throughput. 


This adapter incorporates advanced technologies such as Application Device Queues (ADQ) for optimized traffic steering and Dynamic Device Personalization (DDP) for enhanced packet classification—delivering up to 3× throughput improvements in cloud and NFV workloads. It also supports RoCEv2 and iWARP for low-latency RDMA access, ideal for storage and HPC applications.


Built using the Intel E810 Ethernet controller, the E810-CQDA1 supports virtualization features like SR-IOV and VMDq, along with Intel® VT-c for high-performance cloud and virtualized environments. It also enables flexible port partitioning and endpoint configuration—all programmable via the Ethernet Port Configuration Tool (EPCT).

This adapter excels in delivering high bandwidth with ultra-low latency, making it perfect for storage targets, edge computing, AI clusters, and hybrid cloud services demanding predictable and scalable performance.

Key Features
  • Single QSFP28 port with configurable speeds: 100, 50, 25, or 10 GbE
  • OCP 3.0 mezzanine form factor (also available in low-profile PCIe card)
  • PCIe 4.0 ×16 interface for full throughput support
  • Advanced traffic optimization: ADQ, DDP, EPCT port partitioning
  • Low-latency RDMA with iWARP and RoCEv2 support
  • Virtualization-ready: SR-IOV, VMDq, VT-c
  • Enhanced DPDK and storage offload support (iSCSI, NFS)

Compatibility
This adapter is primarily designed for servers with OCP 3.0 mezzanine slots. It also works with standard PCIe 4.0 x16 slots using the low-profile version. Compatible with Linux, VMware, and other enterprise OSes that support RDMA and advanced Intel virtualization features. Supports DAC, AOC, and optical modules within QSFP28 specifications.

Usage Scenarios

Ideal for hyper-scale data centers, AI/ML clusters, or HPC deployments requiring bandwidth, low latency, and efficient traffic steering.

Perfect for storage appliances and NVMe over Fabrics setups leveraging RDMA protocols.

Supports virtualization and NFV environments requiring flexible, high-throughput network slicing.

Excellent for 5G RAN and mobile edge systems requiring precise timing (PTP v2) and deterministic packet flows.


Frequently Asked Questions
Q1: What data rates does the E810-CQDA1 support?
It supports 100, 50, 25, or 10 GbE speeds per QSFP28 port, configurable via EPCT.

Q2: Does it support RDMA protocols?
Yes—both iWARP and RoCEv2 are supported for low-latency storage and compute acceleration.

Q3: Can I virtualize this adapter?
Absolutely—features like SR-IOV, VMDq, and Intel VT-c provide advanced virtualization support.

Q4: How does the adapter optimize cloud workloads?
With ADQ for traffic steering and DDP for packet classification, it achieves up to threefold throughput gains in cloud and NFV scenarios.
