Intel 25Gb Dual-Port PCIe 4.0 x8 Ethernet Network Adapter (No Bracket). P/N: E810XXVDA2.

This is a genuine Intel 25Gb Dual-Port PCIe 4.0 x8 Ethernet Network Adapter (P/N: E810XXVDA2, K57775-009). Part of the Intel Ethernet Network Adapter E810 series (codenamed "Columbiaville"), this advanced network interface card (NIC) is engineered to deliver high-performance, flexible, and scalable connectivity for demanding data center and cloud environments. It provides two ports of 25 Gigabit Ethernet (25GbE), offering significant bandwidth improvements over 10GbE while maintaining cost efficiency. Leveraging a PCIe 4.0 x8 host interface, it ensures maximum data throughput to and from the server CPU. The E810-XXVDA2 includes Intel's innovative ADQ (Application Device Queues) technology for improved application performance, Dynamic Device Personalization (DDP) for flexible packet processing, and comprehensive virtualization support (SR-IOV). This adapter is ideal for accelerating network-intensive workloads, virtualization, and storage over Ethernet in modern server infrastructures. 

Key Features
