Mellanox MCX416A-BCAT 2-Port 100Gbs QSFP28 PCIE 3.0 x16 Network Card

Product Description

The Mellanox MCX416A-BCAT is a high-performance network interface card (NIC) designed for demanding data center and high-performance computing (HPC) environments. Featuring two 100 Gigabit Ethernet (100GbE) ports, each utilizing the QSFP28 form factor, this card provides exceptional bandwidth and connectivity for servers and storage systems. The QSFP28 connector supports various optical transceivers and direct attach cables, offering flexibility in network deployment. The card connects to the host system via a PCIe 3.0 x16 interface, ensuring sufficient bandwidth to keep pace with the high data rates of the network ports. Based on Mellanox's ConnectX-4 architecture, this NIC is optimized for low latency and high throughput, making it ideal for applications such as high-frequency trading, big data analytics, cloud computing, and storage networking. It supports advanced features like Remote Direct Memory Access (RDMA) and RDMA over Converged Ethernet (RoCE), which allow network traffic to bypass the host CPU and operating system kernel, significantly reducing latency and freeing up CPU resources for application processing. This is crucial for performance-sensitive workloads. Furthermore, the MCX416A-BCAT often includes acceleration technologies such as NVMe-oF (NVMe over Fabrics) support, enabling high-performance access to storage devices over the network. Its robust feature set, including support for virtualization technologies like SR-IOV (Single Root I/O Virtualization), makes it a versatile solution for modern, scalable network infrastructures. The card is typically a full-height, full-length PCIe card, requiring a standard PCIe x16 slot in the host server.
