Product Description
The Mellanox MCX4111A-ACAT is a cutting-edge 25 Gigabit Ethernet Network Interface Card (NIC) designed to meet the demanding requirements of modern data centers and high-performance computing environments. Featuring two 25Gbps SFP28 ports, this card provides exceptional bandwidth and low latency, crucial for applications such as big data analytics, artificial intelligence, and high-frequency trading. The integration of the ConnectX-4 controller ensures robust performance and advanced networking capabilities. Connectivity is established via a PCIe 3.0 x8 host interface, offering ample bandwidth to support the full throughput of both 25Gbps ports without becoming a bottleneck. The use of SFP28 cages allows for flexibility in choosing the appropriate optical transceivers based on network topology and distance requirements. This card is engineered to deliver high efficiency, reduced CPU overhead, and enhanced scalability for enterprise and cloud infrastructures. Beyond basic networking, the MCX4111A-ACAT supports advanced features like RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), which significantly accelerates network traffic by allowing direct memory access between applications on different servers, bypassing the operating system kernel. It also offers support for NVMe over Fabrics (NVMe-oF) and various storage acceleration technologies, making it a versatile solution for storage networking and demanding I/O workloads.
