What is the maximum bandwidth per port on the 900-9X720-007N-SN0?

Each of the four OSFP ports supports 400Gb/s InfiniBand NDR (default mode) or 400 Gigabit Ethernet with full-duplex operation. Total adapter throughput reaches 1.6Tb/s bidirectional, ideal for non-blocking fat-tree fabrics in 4096+ GPU clusters.

Does this ConnectX-7 variant support PCIe Gen5?

Yes, the card features PCIe 5.0 x32 interface at SERDES 32GT/s with full backward compatibility to Gen4/3.0. The integrated PCIe switch enables innovative multi-host topologies without requiring server motherboard modifications or additional riser cards.

What advanced features does this specific SKU include?

This configuration provides multi-host and Socket Direct capabilities, secure boot enabled, crypto disabled, and no heatsink. It's optimized for bare-metal integration into custom AI servers and disaggregated compute architectures where liquid cooling handles thermal management.

Is this card compatible with NVIDIA DGX/HGX platforms?

Yes, designed specifically for DGX H100/B200 and HGX B200 platforms with NVLink switch system integration. Supports NCCL2.18+ all-reduce collectives and GPUDirect Storage for end-to-end pipeline from GPU memory to remote NVMe without CPU involvement.

What cable types are supported on the OSFP ports?

OSFP ports accept passive direct attach copper (DAC) up to 5m, active optical cables (AOC), and transceiver modules including QSFP-DD/OSFP adapters. Supports auto-negotiation across NDR/HDR/EDR InfiniBand speeds and 400/200/100GbE Ethernet modes.

What is the power consumption profile?

Typical power with passive cables in PCIe Gen5 x16 configuration is 19.6W total. Scales with active optics/transceivers and traffic load. PCIe auxiliary power support available through optional connection card for maximum performance configurations.

Product overview

The NVIDIA ConnectX-7 900-9X720-007N-SN0 is a high-performance network adapter card designed for hyperscale data centers, featuring four ConnectX-7 ASICs each supporting 400Gb/s InfiniBand (NDR default) or 400GbE connectivity through OSFP ports. It utilizes PCIe 5.0 x32 interface with an integrated PCIe switch, enabling multi-host and Socket Direct capabilities without requiring additional PCIe slots. This configuration delivers unprecedented bandwidth density for AI training clusters, large-scale HPC simulations, and cloud infrastructure requiring maximum east-west traffic throughput. Key specifications include PCIe Gen5/4.0 compatibility at SERDES 32GT/s, secure boot enabled, crypto disabled, and no heatsink (bare card configuration). The card measures standard PCIe Half Height, Half Length form factor (2.71 x 6.6 inches) with tall bracket support. It excels in RoCEv2, GPUDirect RDMA, and hardware-accelerated networking/storage offloads, reducing CPU utilization by up to 50% in NVMe-oF and distributed storage environments. Ideal for NVIDIA DGX/HGX platforms, InfiniBand fabric deployments, and 400GbE top-of-rack connectivity, this adapter supports advanced features like adaptive routing, congestion control, and telemetry for mission-critical reliability. Its multi-chip design provides redundancy and scalability for next-generation AI factories and exascale computing.
