Description

The NVIDIA MCX545A-CCUN is a cutting-edge 100 Gigabit Ethernet Network Interface Card (NIC) built to meet the demanding requirements of modern data centers and high-performance computing (HPC) environments. Featuring a single QSFP28 port, this card delivers exceptional throughput at speeds of up to 100Gbps, enabling rapid data transfer and communication between servers, storage, and other network devices. The QSFP28 interface supports various high-speed Ethernet standards, providing flexibility for network configurations. Equipped with a PCIe 3.0 x16 host interface, the MCX545A-CCUN ensures maximum bandwidth between the NIC and the server's CPU. This high-speed connection is critical for applications that require low latency and high I/O operations, such as AI/ML workloads, big data analytics, and high-frequency trading. The card is designed to offload network processing tasks from the CPU, further enhancing system efficiency and performance. Beyond raw speed, this NVIDIA NIC incorporates advanced features such as Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE), which allows for direct memory access between servers, bypassing the operating system kernel for significantly reduced latency. It also supports NVMe over Fabrics (NVMe-oF), enabling high-performance access to storage devices over the network. These capabilities make the MCX545A-CCUN an indispensable component for building next-generation, high-performance networks.
