Architecture Overview – Built on Intel® Ethernet 800 Series
The E810-CQDA2 leverages the 800 Series controller architecture, which is optimized for performance consistency, hardware-based packet classification, and programmable pipeline processing.
Key architectural highlights:
- Intel® DDP enables protocol-specific traffic steering for different workloads (e.g., iSCSI, RoCEv2).
- Advanced load balancing across cores via ADQ and RSS enhances application performance.
- SR-IOV & VMDq ensure virtualization-ready throughput in hyper-converged environments.
- Support for RDMA (iWARP and RoCEv2) reduces CPU load for latency-sensitive applications.
Performance for Next-Gen Data Centers
High Throughput & Scalability
With dual 100GbE support over QSFP28, the E810-CQDA2 enables scalable bandwidth for:
- Large-scale data analytics
- Hyperconverged infrastructure (HCI)
- High-performance storage solutions (NVMe over Fabrics)
- AI and ML pipeline acceleration
- Cloud-native and containerized workloads
Latency Optimization
- ADQ enables deterministic latency by isolating and prioritizing traffic queues.
- Hardware timestamping enables precise time synchronization for financial or telco applications.
Use Cases of Intel® Ethernet Network Adapter E810-CQDA2
1. Cloud and Virtualized Environments
With support for SR-IOV and DPDK, this adapter ensures efficient I/O virtualization and packet processing for virtualized workloads in OpenStack, VMware, and Kubernetes ecosystems.
2. NFV & Edge Computing
Dynamic Device Personalization (DDP) allows service providers to program the adapter for specific network functions—enhancing packet filtering, classification, and forwarding in edge and NFV environments.
3. High-Performance Storage Networks
Support for NVMe over Fabrics, RoCEv2, and iWARP makes this adapter ideal for storage area networks demanding low latency and high throughput.
4. AI/ML Workload Infrastructure
As AI/ML workloads generate massive data transfers between GPUs, CPUs, and storage, the E810-CQDA2 delivers the bandwidth and efficiency required for training pipelines and real-time inference.
Compatibility and Integration
The E810-CQDA2 is validated across a wide array of enterprise operating systems and virtualization platforms. It supports:
- Windows Server 2019/2022
- Red Hat Enterprise Linux 8/9
- Ubuntu 20.04/22.04 LTS
- SUSE Linux Enterprise Server
- VMware ESXi 7.0 and 8.0
Intel also provides open-source drivers and firmware updates via GitHub and vendor repositories for streamlined deployment.
Security and Telemetry
Hardware-based Security
- Secure firmware update
- Anti-rollback protection
- UEFI Secure Boot compatibility
Advanced Telemetry
Built-in telemetry and monitoring capabilities provide insights into packet drops, port health, traffic types, and queue stats—essential for proactive diagnostics and SLA assurance.
Deployment Considerations
Form Factor & Cabling
