Product Description
The Mellanox ConnectX-4 MCX4121C-LOW is a cutting-edge network interface card (NIC) engineered to deliver exceptional performance and scalability for modern data centers and high-performance computing (HPC) clusters. Equipped with two 25 Gigabit Ethernet ports, each utilizing SFP28 cages, this adapter provides substantial bandwidth crucial for data-intensive workloads such as AI/ML training, big data analytics, and high-frequency trading. The 25Gb/s speed per port offers a significant upgrade over traditional 10GbE solutions, enabling faster data movement and reduced latency. Designed with a low-profile form factor, the MCX4121C-LOW is optimized for deployment in dense server environments where space is at a premium. Its PCI-Express 3.0 x8 interface ensures a high-bandwidth connection to the host system, preventing bottlenecks and maximizing the throughput of the network ports. This adapter supports a rich set of advanced networking features, including Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which allows network traffic to bypass the CPU and kernel for lower latency and higher efficiency. It also supports NVMe over Fabrics (NVMe-oF) for high-performance storage access and Single Root I/O Virtualization (SR-IOV) for improved virtual machine I/O performance. The ConnectX-4 architecture is renowned for its efficiency and reliability. The MCX4121C-LOW is built to handle the demanding requirements of cloud computing, storage networking, and virtualized environments. Its ability to offload network tasks from the CPU frees up valuable processing resources for applications, leading to improved overall system performance and cost-effectiveness. The flexibility of SFP28 cages allows for the use of various optical transceivers, enabling compatibility with different network infrastructures and distances.
