About the Intel Ethernet Network Adapter E810-2CQDA2T
The Intel Ethernet Network Adapter E810-2CQDA2T delivers two ports of 100 Gigabit Ethernet, providing 200 Gbps of aggregate bandwidth for high-speed data center interconnect and storage fabric applications. Each port supports QSFP28 connectivity with multiple media options including 100GBASE-CR2 DAC, 100GBASE-SR2, and 100GBASE-LR2, enabling flexible deployment across short-reach and long-reach network topologies. The adapter connects via PCIe 4.0 x16 host interface and includes both standard low-profile and full-height brackets, making it suitable for diverse server form factors. Intel built this adapter around the Intel Ethernet Controller E810, delivering deterministic performance for mission-critical workloads.
Data center network engineers and infrastructure architects choose the E810-2CQDA2T for its advanced offload capabilities and traffic management features. The adapter supports RoCEv2 hardware offload for low-latency RDMA operations, up to 256 virtual functions per port via SR-IOV, and hardware-based Flow Director for precise packet steering to specific queues. Intel included support for tunnel encapsulation and decapsulation across VXLAN, GENEVE, and GRE protocols, alongside IEEE 1588 PTP hardware timestamping for synchronized cluster operations. Application Device Queues enable per-application traffic isolation, while DPDK support unlocks custom packet processing pipelines. The adapter operates across RHEL, SUSE Linux, Windows Server, VMware ESXi, and FreeBSD environments with typical power consumption around 24W and an operating temperature range from 0°C to 55°C.
Organizations requiring ultra-high-speed, low-latency networking with offload-rich feature sets should evaluate the E810-2CQDA2T for their next-generation infrastructure refresh.

Frequently Asked Questions about Intel Ethernet Network Adapter E810-2CQDA2T
Does the Intel Ethernet Network Adapter E810-2CQDA2T support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
