NVIDIA ConnectX-7 VPI Adapter – Dual-Port NDR 400Gb/s, PCIe 5.0, GPUDirect, RoCE

The NVIDIA ConnectX-7 VPI adapter MCX755106AS-HEAT is a dual-port 200Gb/s smart network interface card designed for high-performance computing (HPC) clusters, AI factories, and enterprise data centers. Combining InfiniBand and Ethernet protocol support, it enables Remote Direct Memory Access (RDMA), GPUDirect Storage, and advanced in‑network computing engines such as SHARPv3 and rendezvous offload. With PCIe 5.0 host interface and hardware-based security accelerators, this adapter offloads the CPU, reduces TCO, and delivers consistent low-latency performance.

Ideal for organizations modernizing their IT infrastructure from edge to core, the ConnectX-7 family brings software-defined, hardware-accelerated networking, storage, and security — empowering scalable and secure solutions with minimal overhead.

ConnectX-7 integrates NVIDIA ASAP² (Accelerated Switch and Packet Processing) technology to deliver software-defined networking at line-rate without consuming CPU cores. Inline hardware engines handle encryption/decryption for IPsec, TLS, and MACsec, protecting data in motion from edge to core. For storage, built-in NVMe-oF offload and GPUDirect Storage enable direct data movement between storage and GPU memory, reducing latency and maximizing throughput. The adapter also supports advanced time synchronization (PTP with 12ns accuracy) and on‑demand paging (ODP) for registration‑free RDMA, making it ideal for disaggregated and memory-centric architectures.

• AI & Large Language Model (LLM) Clusters: High-speed interconnect for GPU servers, leveraging GPUDirect RDMA and SHARP collective offloads.
• High-Performance Computing (HPC): 200Gb/s HDR InfiniBand fabric for MPI, OpenSHMEM, and scientific simulations.
• Hyperscale Cloud & SDN Data Centers: RoCEv2, overlay acceleration, and SR-IOV for multi-tenant virtualization.
• Enterprise Security Gateway: Inline MACsec/IPsec encryption for edge-to-core communications with hardware offload.
• Storage Systems: NVMe-oF/TCP offload, distributed storage platforms requiring ultra-low latency and high IOPS.

*Specifications are based on NVIDIA public documentation. Verify exact configuration for your system before ordering.

• Ultra-low latency & high throughput: Hardware RDMA and in‑network computing minimize application tail latency.
• Unified fabric: One adapter supports both InfiniBand and Ethernet, simplifying inventory and deployment.
• Future-proof PCIe 5.0: 32 GT/s per lane, double bandwidth of PCIe 4.0, removing I/O bottlenecks.
• Reduced TCO: Offloads CPU from networking, storage, and security tasks, enabling more efficient server utilization.
• AI-optimized: Native GPUDirect and SHARPv3 collective operations accelerate model training and inference.

Hong Kong Starsurge Group Co., Limited provides end‑to‑end support including pre-sales consulting, custom firmware configuration, and worldwide shipping. All ConnectX-7 adapters are backed by a 1-year warranty (extendable) and technical assistance from experienced network engineers. We offer multilingual support, RMA services, and fast replacement logistics to minimize downtime.

• Ensure PCIe slot provides sufficient power (75W via slot, no auxiliary power required for standard operation).
• Check physical clearance: HHHL form factor fits in most 1U/2U servers; OCP variants require corresponding mezzanine slot.
• For RoCE deployment, configure DCB (Priority Flow Control) and ECN on switches for lossless Ethernet.
• Always update firmware to latest stable version to leverage security and performance enhancements.
