Product Description
The Lenovo 4XC7A08229 adapter card leverages the advanced capabilities of the Mellanox ConnectX-5 technology to deliver exceptional 40 Gigabit Ethernet performance. Equipped with two QSFP28 ports, it provides high-density, high-speed connectivity essential for modern data centers, high-performance computing (HPC), and artificial intelligence (AI) workloads. The QSFP28 interface supports high-speed optical transceivers, enabling flexible and efficient network configurations. This adapter is built on the PCIe Gen4 interface, offering double the bandwidth of PCIe Gen3, which is crucial for maximizing the performance of 40Gb/s network speeds and preventing bottlenecks. The ConnectX-5 architecture is specifically designed for low-latency applications, incorporating features like RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE) and GPUDirect, which significantly accelerate data transfers between compute nodes and storage, and between GPUs. Ideal for demanding environments such as cloud infrastructure, big data analytics, and machine learning, the 4XC7A08229 provides the necessary throughput and low latency to support these intensive applications. Its advanced feature set, including network virtualization support and enhanced offloads, contributes to improved server efficiency and reduced CPU overhead. This adapter represents a high-performance networking solution for organizations pushing the boundaries of data processing and computational power.
