Dell 21WF2 E810XXVDA2 2-Ports 25GbE SFP28 PCIe Adapter

Product Description

The Dell 21WF2 is a high-performance network adapter card featuring two 25 Gigabit Ethernet (25GbE) ports, each equipped with SFP28 connectors. This adapter is built around the advanced Intel E810XXVDA2 controller, renowned for its robust capabilities in delivering high throughput and low latency network connectivity. The dual-port design allows for increased bandwidth and redundancy, making it suitable for critical server applications and high-demand network environments. Leveraging the PCIe Gen 4.0 x8 interface, the 21WF2 ensures that the network adapter can keep pace with the fastest server CPUs and memory subsystems, minimizing potential bottlenecks. The integration of the Intel E810XXVDA2 chipset brings support for cutting-edge networking technologies. This includes Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE v2), which offloads network processing from the CPU, leading to significant performance gains in latency-sensitive applications. It also supports advanced network virtualization features like VXLAN, NVGRE, and GENEVE, essential for modern cloud infrastructures and containerized environments. Furthermore, the Dell 21WF2 adapter is equipped with Single Root I/O Virtualization (SR-IOV) capabilities, which enhance the performance of virtual machines by providing them with direct access to the network adapter's hardware resources. This reduces overhead and improves I/O performance in virtualized environments. The combination of high port speeds, advanced controller features, and a high-bandwidth PCIe interface makes the 21WF2 an ideal choice for data centers, high-performance computing clusters, and enterprise servers requiring superior network performance.
