Intel Dual Port PCI Express 4.0X16 Ethernet Network Adapter

The Intel E810CQDA2G2P5 is an Ethernet network adapter that gives any compatible server two network links able to carry up to 100 gigabits of data per second. It drops into a PCI Express 4.0 x16 slot, so the host bus keeps pace with the line-rate traffic, helping critical workloads move information without an internal bottleneck.

At the center of the card sits Intel’s E810 controller, a design that balances high throughput with dependable performance. Virtualization features such as SR-IOV, VMDq, and Flexible Port Partitioning let administrators assign bandwidth precisely to individual virtual machines or containers, keeping noisy neighbors from affecting latency-sensitive services.

Each port terminates in a QSFP28 cage that works with direct-attach copper cables, active optical cables, or fiber transceivers. This flexibility makes the adapter a practical choice for top-of-rack links inside a single enclosure, spine-leaf uplinks across the data hall, or ongoing migrations where mixed cabling is unavoidable. The ports can also step down to 50, 25, or 10 gigabit speeds when connecting to legacy switches.

Intelligent offloads and advanced traffic management features reduce CPU overhead, which is valuable when hosting dense virtual environments, database clusters, or storage nodes that use iSCSI or NFS. By keeping packet processing on the adapter, system resources remain available for the applications that drive revenue or research.

Whether you are modernizing a cloud pod, expanding an enterprise storage array, or building a high-performance computing cluster, this card delivers the bandwidth headroom and feature set required. Both full-height and low-profile brackets ship in the box, so the adapter fits easily into standard rack servers, compact edge nodes, or workstations on the lab bench.
