Product Description
NVIDIA ConnectX-7 MCX75310AAS-NEAT: 400G Smart Networking Adapter
The NVIDIA ConnectX-7 MCX75310AAS-NEAT is a high-performance dual-port network interface card (NIC) designed for modern, demanding data center environments. This advanced network card supports both InfiniBand and Ethernet protocols, delivering up to 400Gb/s per port. It is engineered to accelerate AI, machine learning, high-performance computing (HPC), and cloud-scale workloads through hardware-accelerated networking, storage, and security functions. Also identified by the alias mq9700, this adapter provides the ultra-low latency and extreme throughput required for data-driven applications.
Product Overview
The NVIDIA ConnectX-7 MCX75310AAS-NEAT is a versatile, high-speed network adapter card that serves as a critical component for building scalable and efficient data center infrastructures. It combines cutting-edge networking technologies with robust hardware acceleration to offload CPU workloads, reduce latency, and maximize data throughput. This NIC card is particularly suited for environments where performance, reliability, and intelligent networking are paramount.
Key Characteristics
- Dual-Protocol Support: Operates seamlessly with both InfiniBand and Ethernet networks
- Extreme Bandwidth: Delivers up to 400Gb/s per port, with support for NDR InfiniBand and 400GbE
- Hardware Acceleration: Comprehensive offload engines for networking, storage (NVMe-oF, GPUDirect Storage), and security (IPsec, TLS, MACsec)
- Advanced RDMA: Full support for RDMA over Converged Ethernet (RoCE) and native InfiniBand RDMA, enabling direct memory access between servers and storage
- In-Network Computing: Integrates NVIDIA SHARP™ technology for collective operation offloads, reducing CPU overhead in HPC and AI clusters
- Precision Timing: Provides hardware-assisted IEEE 1588 PTP capabilities; supported timing features depend on the selected SKU and configuration
Core Technologies & Standards
This smart network card is built on a foundation of industry-leading technologies and complies with key standards:
- Networking: InfiniBand Trade Association 1.5, Ethernet IEEE 802.3 (10G to 400GbE), RoCE v2, VXLAN/GENEVE overlay offload
- Interconnect: PCI Express 5.0 x16 host interface, supporting the latest server platforms
- Security: Inline hardware acceleration for IPsec, TLS 1.3, and MACsec (AES-GCM 128/256)
- Virtualization: SR-IOV (Single Root I/O Virtualization) for efficient virtual machine connectivity
- Management: NC-SI, Redfish, PLDM (Platform Level Data Model) for firmware and device management
Working Principle
The ConnectX-7 NIC card functions as an intelligent data plane processor installed in a server's PCIe slot. It offloads network, storage, and security processing tasks from the host CPU to its dedicated hardware engines. For data transfer, it utilizes Remote Direct Memory Access (RDMA) to enable direct, kernel-bypass communication between application memory spaces across the network, drastically reducing latency and CPU utilization. Its programmable pipeline and parsing engine handle complex packet processing, encapsulation (like VXLAN), and security protocols at line rate, ensuring maximum performance for virtualized and bare-metal deployments.
Application Scenarios
- Artificial Intelligence & Machine Learning: Accelerates distributed training by providing high-throughput, low-latency connectivity between GPUs and compute nodes
- High-Performance Computing (HPC): Essential for scientific simulations, climate modeling, and financial analytics clusters requiring massive parallel communication
- Hyperscale Cloud Data Centers: Enables high-density virtualized environments, software-defined networking (SDN), and efficient storage disaggregation
- High-Frequency Trading & Real-Time Analytics: Delivers the microsecond latency and precise time synchronization needed for time-sensitive decision making
- Enterprise Storage & Data Backup: Optimizes performance for NVMe-oF and GPUDirect Storage, facilitating fast access to centralized storage pools
