NVIDIA Mellanox ConnectX-7 MCX755106AS-HEAT 400Gb/s NDR InfiniBand Smart Network Adapter

Engineered for AI factories, scientific computing, and hyperscale cloud environments, the ConnectX-7 MCX755106AS-HEAT delivers 400Gb/s throughput, sub-microsecond latency, and hardware-accelerated inline security (IPsec/TLS/MACsec). Supports PCIe Gen5 x16, GPUDirect RDMA, and advanced in-network computing offloads.

The NVIDIA ConnectX-7 family represents a breakthrough in RDMA networking, supporting both InfiniBand and Ethernet protocols up to 400Gb/s. The specific model MCX755106AS-HEAT is a high-density single-port NDR InfiniBand adapter designed for demanding HPC and AI clusters. It integrates PCIe Gen5 host interface, hardware offloads for NVMe-oF, collective communications (SHARP), and inline encryption engines, enabling users to build secure, ultra-efficient data centers with lower TCO.

The ConnectX-7 MCX755106AS-HEAT incorporates NVIDIA's latest in-network computing engines. It offloads critical data path tasks from the CPU:

Large-scale GPU clusters (NVIDIA DGX/HGX) requiring GPUDirect RDMA and SHARP offloads for NCCL/UCC acceleration.

Weather modeling, molecular dynamics, genome research -- MPI libraries (OpenMPI, MVAPICH) with adaptive routing.

Overlay networking, VXLAN offload, and ASAP2 flow processing for software-defined data centers.

High-performance disaggregated storage leveraging RDMA and hardware NVMe-oF target offload.

In-box drivers for Linux (RHEL, Ubuntu, Debian), Windows Server, VMware ESXi (SR-IOV), and Kubernetes/Container environments.

When selecting the MCX755106AS-HEAT, consider port speed (NDR), host slot (PCIe Gen5 x16) and form factor (HHHL). For dual-port or OCP 3.0 requirements, refer to the full ConnectX-7 portfolio:

Hong Kong Starsurge Group Co., Limited provides global logistics, technical consulting, and warranty support. Each adapter undergoes pre-ship validation. Services include:

This model is a single-port NDR InfiniBand HHHL adapter equipped with full inline security engines and PCIe Gen5 x16 interface, primarily targeting HPC and AI clusters requiring 400G per port.

Yes, ConnectX-7 supports dual protocol (InfiniBand / Ethernet), but MCX755106AS-HEAT is typically InfiniBand-focused. For Ethernet-only or dual-protocol need, please consult the VPI ordering guide.

Passive heatsink design; typical power consumption: Not publicly specified. Please confirm power/thermal requirement for server integration before ordering.

Yes, PCIe Gen5 is backward compatible with Gen4 slots, but will operate at Gen4 speeds (max 200Gb/s per port effective bandwidth limited by host).
