The NVIDIA Mellanox MCX653106A-HDAT-SP is a flagship ConnectX-6 (CX6) series virtual protocol interconnect (VPI) adapter designed to provide industry-leading performance for high-growth workloads. As the world’s first 200Gb/s HDR InfiniBand and 200GbE Ethernet adapter card, it offers a perfect balance of high bandwidth, sub-microsecond latency, and high message rates.
Equipped with a PCIe 4.0 x16 interface and dual QSFP56 ports, this single-pack (SP) retail-ready adapter is the ideal solution for enterprises and service providers building mission-critical infrastructures, including AI training clusters, High-Performance Computing (HPC), and hyper-scale cloud data centers.
Product Description
NVIDIA MCX653106A-HDAT-SP ConnectX-6 VPI Adapter Card HDR InfiniBand and 200GbE Dual-Port QSFP56 PCIe 4.0 x16 Tall Bracket (-SP indicates Single Pack)
ConnectX-6 VPI Card 200Gb/s InfiniBand & Ethernet Adapter Card
ConnectX-6 Virtual Protocol Interconnect (VPI) cards are a groundbreaking addition to the ConnectX series of industry-leading network adapter cards. Providing two ports of 200Gb/s for InfiniBand and Ethernet connectivity, sub-600ns latency and 215 million messages per second, ConnectX-6 VPI cards enable the highest performance and most flexible solution aimed at meeting the continually growing demands of data center applications. In addition to the innovative features of previous versions, ConnectX-6 cards offer enhancements that further improve performance and scalability.
ConnectX-6 VPI supports HDR, HDR100, EDR, FDR, QDR, DDR, and SDR InfiniBand speeds as well as 200, 100, 50, 40, 25, and 10Gb/s Ethernet speeds.
Key Features
Dual-Protocol Connectivity (VPI): Seamlessly supports both 200Gb/s HDR InfiniBand and 200GbE Ethernet, providing maximum flexibility for diverse networking environments.
PCIe 4.0 Support: Fully compatible with PCIe 4.0 (and backward compatible with PCIe 3.0), doubling the available bandwidth to the CPU and significantly reducing performance bottlenecks.
Smart Offloading Technology: Features advanced hardware offloads such as RDMA (RoCE), ASAP² (Accelerated Switching and Packet Processing), and NVMe-over-Fabrics (NVMe-oF), which offload network processing from the CPU to maximize application performance.
Enhanced Security: Built-in Hardware Root of Trust and secure boot capabilities ensure your data center remains protected against firmware-level attacks.
Optimal Efficiency: Delivers high throughput with low power consumption and small CPU overhead, ensuring a lower Total Cost of Ownership (TCO).
