NVIDIA ConnectX-7 MCX75310AAS-HEAT 400G Network Adapter

The NVIDIA ConnectX-7 MCX75310AAS-HEAT is a high-performance dual-port network card supporting both InfiniBand and Ethernet protocols at speeds up to 400Gb/s. Designed for modern data centers, this advanced NIC delivers ultra-low latency, hardware-accelerated security, and support for RDMA and RoCE, making it ideal for AI, machine learning, high-performance computing, and cloud infrastructures.

Key Features

• Dual-port 400G InfiniBand and Ethernet support
• Hardware-offloaded RDMA and RoCE for low CPU utilization
• Advanced security with inline TLS, IPsec, and MACsec encryption
• GPUDirect® RDMA and Storage support for GPU-to-GPU communication
• Support for NVIDIA SHARP™ in-network computing

Core Technologies

The ConnectX-7 network card leverages cutting-edge technologies including PCIe Gen 5.0, PAM4 signaling, and hardware-accelerated networking protocols. It supports InfiniBand NDR (400G), HDR (200G), and EDR (100G), as well as Ethernet speeds from 10G to 400G. Key protocols include RDMA, RoCE, SR-IOV, NVMe over Fabrics, and advanced timing synchronization via IEEE 1588 PTP.

How It Works

The ConnectX-7 NIC offloads network processing from the host CPU through dedicated hardware engines. It uses RDMA to enable direct memory access between systems, reducing latency and improving throughput. In-network computing capabilities like SHARP allow aggregation and reduction operations to be performed within the switch fabric, further accelerating collective operations in HPC and AI workloads.

Applications

• Artificial Intelligence and Deep Learning Training
• High-Performance Computing (HPC) Clusters
• Cloud Data Centers and Hyper-Scale Infrastructure
• Storage Area Networks (SAN) and NVMe over Fabrics
• Real-Time Data Analytics and Financial Modeling

Specifications

Advantages

• Superior throughput and lower latency compared to previous generations like ConnectX-6
• Hardware-offloaded encryption enhances security without performance loss
• Support for NVIDIA Multi-Host technology enables shared adapter access
• Advanced timing and synchronization for precision-critical applications
• Comprehensive driver support for Linux, Windows, and virtualization platforms

Frequently Asked Questions

Q: Is this network card compatible with existing ConnectX-6 infrastructure?
A: Yes, the ConnectX-7 NIC is backward compatible with earlier InfiniBand and Ethernet standards.

Q: Does it support virtualization?
A: Yes, SR-IOV and VirtIO acceleration are supported for high-performance virtualized environments.

Q: What cables are required for 400G operation?
A: You will need NDR InfiniBand or 400G Ethernet compatible cables and transceivers.

Precautions

• Ensure proper cooling as the adapter may operate at high temperatures under full load.
• Verify PCIe slot compatibility (PCIe Gen5 x16 recommended).
• Use certified optical or DAC cables for optimal signal integrity.
• Update to the latest firmware and drivers for full feature availability.
