Product Description
The Dell CX422A, based on the Mellanox ConnectX-4 technology, is a high-performance Network Daughter Card (NDC) designed to deliver exceptional network throughput and low latency. It features two 25 Gigabit Ethernet (25GbE) SFP28 ports, enabling extremely fast data transfer rates crucial for modern data centers, cloud computing environments, and high-performance computing (HPC) clusters. The card connects to the host system via a PCIe Gen3 x16 interface, providing ample bandwidth to support the high-speed network connections. This network adapter is engineered to accelerate applications by minimizing network overhead and latency. It supports advanced features such as Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which allows network traffic to bypass the CPU and operating system kernel, directly accessing memory on the host and target systems. This significantly reduces latency and improves overall system performance for storage, compute, and communication-intensive workloads. The Dell CX422A is an ideal solution for servers and workstations that require high-speed connectivity for tasks like large-scale data analytics, machine learning, high-frequency trading, and virtualization. Its dual-port design offers redundancy and increased bandwidth, ensuring reliable and efficient network communication in demanding enterprise environments. The SFP28 form factor allows for flexible deployment with various optical transceivers.
