Description
The Dell K07HG, featuring the Mellanox ConnectX-4 CX4421A chipset, is a high-performance dual-port 25 Gigabit Ethernet (25GbE) network daughter card. This adapter is engineered to deliver exceptional network throughput and low latency, making it an ideal solution for demanding server and storage applications in modern data centers, high-performance computing (HPC) clusters, and cloud environments. With two 25GbE ports, each utilizing SFP28 transceivers (sold separately), this card provides significant bandwidth for data-intensive workloads. The ConnectX-4 architecture is known for its efficiency, offloading network tasks from the host CPU and enabling advanced features such as RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE) and NVMe-oF, which further reduce latency and improve application performance. The daughter card form factor is designed for integration into specific server chassis that support this type of expansion card. Its PCIe interface ensures high-speed communication with the server's motherboard. The K07HG is a critical component for building scalable and high-performance network infrastructures, enabling faster data transfers, improved application responsiveness, and efficient resource utilization.
