Intel PCIe 4.0 x16 - QSFP28 x 2 Ethernet Network Adapter

The Intel E810CQDA2 is a network adapter that fits into a PCIe 4.0 x16 slot and provides two QSFP28 ports, each capable of running up to 100 Gb Ethernet. It is designed for servers that handle large data flows, whether those flows come from cloud workloads, AI training jobs, or storage clusters that move enormous files around the clock.

By offering QSFP28 connectivity, the adapter lets you choose either copper or fiber cabling, so you can match existing infrastructure or future-proof a new rack without buying additional hardware. Each port supports 100, 50, 25, or 10 Gb speeds, giving network architects room to balance bandwidth and budget while maintaining a single card type across multiple deployment tiers.

Performance features such as RDMA over Converged Ethernet (iWARP and RoCEv2) reduce CPU overhead and latency during east-west traffic in microservice architectures or clustered databases. Dynamic Device Personalization adjusts packet processing on the fly, which improves efficiency for diverse protocols like storage over Ethernet or 5G user-plane data.

Virtual machine density also improves because the adapter includes hardware-assisted virtualization and single-root I/O virtualization. These capabilities carve out network resources for each VM or container, so tenants get predictable throughput without the administrative hassle of separate physical interfaces.

Installation is straightforward: full-height and low-profile brackets ship in the box, so the card slips into standard or compact chassis with equal ease. Support for IEEE 1588 Precision Time Protocol keeps distributed applications such as financial trading, media production, or scientific simulation in tight sync.
