Product Description
The NVIDIA MCX623105AN-VDAT is a cutting-edge network adapter card engineered to deliver exceptional performance for the most demanding data center and high-performance computing (HPC) workloads. Featuring two QSFP56 ports, this adapter supports ultra-high-speed networking, capable of achieving up to 200 Gigabits per second (GbE) per port, for a combined aggregate bandwidth of 400GbE. This makes it ideal for applications requiring massive data throughput and low latency, such as AI/ML training, big data analytics, and high-frequency trading. Leveraging the latest PCI-Express 4.0 x16 interface, the MCX623105AN-VDAT ensures maximum bandwidth between the network adapter and the host system, eliminating potential bottlenecks. The card is built upon NVIDIA's advanced ConnectX-6 Virtual Protocol Interconnect (VPI) technology, which provides a unified solution for Ethernet and InfiniBand, offering flexibility and scalability. It supports advanced features like RDMA over Converged Ethernet (RoCEv2), enabling efficient direct memory access between servers and reducing CPU overhead. Beyond raw speed, this adapter card incorporates intelligent offloads and acceleration engines to further optimize network performance. Features such as GPUDirect RDMA enhance data transfer efficiency for GPU-accelerated applications. The NVIDIA MCX623105AN-VDAT is designed for environments where performance, scalability, and efficiency are paramount, providing a robust foundation for next-generation data centers and supercomputing clusters.
