Product Description
The Mellanox MCX4111A-ACUT is a high-performance dual-port 25 Gigabit Ethernet (25GbE) Network Interface Card (NIC) designed to deliver cutting-edge connectivity for demanding data center and high-performance computing (HPC) environments. Leveraging the advanced Mellanox ConnectX-4 architecture, this adapter provides exceptional throughput and ultra-low latency, crucial for applications such as AI/ML training, big data analytics, and high-frequency trading. The card utilizes SFP28 connectors, supporting 25GbE speeds for each of its two ports. Equipped with a PCIe 3.0 x8 host interface, the MCX4111A-ACUT ensures ample bandwidth between the NIC and the host system, preventing bottlenecks and maximizing data transfer efficiency. It supports key technologies like Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which allows network adapters to transfer data directly between the memory of different servers without involving the CPU, significantly reducing latency and improving application performance. Furthermore, it offers support for NVMe over Fabrics (NVMe-oF), enabling high-speed access to NVMe storage devices over the network. For virtualized environments, the MCX4111A-ACUT includes support for Single Root I/O Virtualization (SR-IOV), which allows a single PCIe device to appear as multiple separate devices to virtual machines, enhancing I/O performance and efficiency. This makes it an ideal choice for cloud providers, enterprise data centers, and research institutions seeking to optimize their network infrastructure for speed, scalability, and efficiency.
