Product Description
The Mellanox MCX516A-CCHT is a cutting-edge network interface card designed for the most demanding data center and high-performance computing environments. Leveraging the powerful ConnectX-5 architecture, this adapter provides two 100 Gigabit Ethernet ports, each equipped with QSFP28 connectors, enabling extremely high-speed network connectivity. The card utilizes a PCIe 3.0 x16 interface, ensuring that the full bandwidth potential of the network ports can be realized without becoming a bottleneck for the host system. This NIC is engineered with advanced features to accelerate network and storage workloads. It supports Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which allows network traffic to bypass the host CPU and kernel, significantly reducing latency and improving throughput for applications like distributed storage, high-frequency trading, and large-scale data analytics. Furthermore, the MCX516A-CCHT incorporates hardware offload engines for various protocols, including TCP/UDP/IP, NVGRE, and VXLAN, which further reduce CPU utilization and enhance overall system efficiency. Ideal for AI/ML training clusters, big data analytics platforms, cloud infrastructure, and high-performance storage solutions, the Mellanox MCX516A-CCHT offers unparalleled performance, scalability, and efficiency. Its dual-port design provides redundancy and increased bandwidth options, making it a versatile choice for modern, high-density server deployments that require robust and high-speed network connectivity.
