Intel Ethernet Adapter E810-XXVDA2 25GbE Dual Port PCIe 4.0 x8 Optical

The Intel Ethernet Adapter E810-XXVDA2 brings 25-gigabit Ethernet speed to any server, workstation or high-performance client. Two SFP28 ports let you connect optical fiber links, delivering reliable, high-capacity connections over long distances while using only one PCI Express slot. Built on the Intel 800 Series, the card leverages PCIe 4.0 x8 to provide the bandwidth needed for demanding cloud, enterprise and storage workloads. Application Device Queues (ADQ) create dedicated traffic paths, cutting latency and boosting throughput for latency-sensitive applications. Dynamic Device Personalization automatically tailors packet processing to the active protocol, improving efficiency without manual tuning. The dual-port design fits into a single expansion slot, freeing up space for additional components while delivering the performance required by next-gen web-scale environments. Because it uses optical fiber, the adapter can bridge servers across data-center racks or to external switches without the signal loss common to copper cables. This makes it ideal for high-availability clusters, storage arrays, and any scenario where consistent, low-latency connectivity is essential.
