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
