Product Description
The Mellanox MCX566A-CDAB is a cutting-edge network adapter designed to meet the extreme bandwidth and low-latency requirements of modern high-performance computing (HPC), artificial intelligence (AI), machine learning (ML), and data center environments. Equipped with two 100 Gigabit Ethernet (GbE) QSFP28 ports, this card provides a total aggregate bandwidth of up to 200 Gbps, enabling massive data transfers and high-speed interconnectivity. The card leverages the PCIe 4.0 x16 interface, offering significantly higher bandwidth compared to previous PCIe generations. This ensures that the NIC is not a bottleneck for the host system, allowing CPUs and accelerators to communicate with the network at full speed. The ConnectX-5 architecture is renowned for its advanced offload capabilities, including Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) and Internet Wide Area RDMA Protocol (iWARP), which reduce CPU utilization and improve application performance by allowing direct memory access between nodes. Furthermore, the MCX566A-CDAB supports features like NVMe-oF (NVMe over Fabrics) offload, enhancing storage performance for networked storage solutions, and various virtualization acceleration technologies. These capabilities make it an ideal choice for building scalable, efficient, and high-performance network infrastructures in demanding enterprise and research settings.
