NVIDIA ConnectX-7 MCX755106AS-HEAT 200G InfiniBand Network Adapter

The NVIDIA ConnectX-7 MCX755106AS-HEAT is a high-performance dual-port InfiniBand network card designed for next-generation data centers and high-performance computing environments. This advanced network interface card delivers 200Gb/s per port bandwidth, ultra-low latency, and hardware-accelerated features that make it ideal for AI training, scientific simulations, and cloud infrastructure. Building upon the success of the ConnectX-6 series, this network card offers enhanced performance and capabilities for the most demanding workloads.

Key Characteristics

• Dual-port HDR InfiniBand (200Gb/s per port)
• PCI Express Gen 5.0 x16 host interface
• Hardware-offloaded RDMA operations
• GPUDirect® RDMA and Storage technology
• Enhanced NVIDIA SHARP™ in-network computing
• Hardware-accelerated security encryption
• SR-IOV virtualization support

Advanced Technologies

This InfiniBand network card incorporates cutting-edge technologies including PCIe 5.0 interface, PAM4 signaling, and hardware-offloaded protocols. It supports InfiniBand HDR (200G) and EDR (100G) speeds, with compatibility for earlier generations. The NIC features comprehensive RDMA capabilities, NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP), and enhanced congestion control mechanisms for optimal performance in large-scale deployments.

Operational Principle

The ConnectX-7 network card operates by offloading network processing tasks from the host CPU to specialized hardware engines. Through Remote Direct Memory Access (RDMA), it enables direct memory-to-memory data transfer between systems without CPU involvement, significantly reducing latency. The integrated network card processor handles protocol processing, traffic management, and security functions, delivering line-rate performance regardless of packet size.

Application Scenarios

• Artificial Intelligence and Deep Learning clusters
• High-Performance Computing (HPC) systems
• Hyper-scale cloud data centers
• High-frequency trading systems
• Scientific research and simulation environments
• Storage Area Networks (SAN) and NVMe over Fabrics

Technical Specifications

Competitive Advantages

The ConnectX-7 network card represents a significant advancement over previous generations like the ConnectX-6, offering 2x the bandwidth and improved energy efficiency. This high-performance NIC card features enhanced in-network computing capabilities through SHARP technology, reducing MPI operation time by offloading collective operations to the switch network. The hardware-accelerated security engine provides inline encryption without performance degradation, making this network adapter ideal for secure environments.
