N9570-128QC, 128x400G QSFP112, NVIDIA Spectrum-4 51.2Tbps, Enterprise SONiC by NADDOD, for AI/ML/Cloud Data Center/HPC
The N9570-128QC is purpose-built for future-ready data centers, driving performance in AI/ML, hyperscale cloud, and HPC environments through its full adherence to the SONiC Network Operating System. Powered by NVIDIA Spectrum-4 high-performance silicon, it delivers unprecedented bandwidth, deterministic ultra-low latency, and sophisticated congestion management. This foundational design empowers organizations to architect a highly scalable, cost-efficient, and energy-optimized network infrastructure.
The N9570-128QC switch offers versatile deployment, delivering extreme performance in both Leaf and Spine layers:
As a Leaf-layer switch, it connects up to 128 servers with 400G NICs directly. It also supports port breakout for up to 256 x 200GbE or 512 x 100GbE connections.
As a Spine-layer switch, it utilizes its 128 x 400GbE ports to downlink to up to 128 Leaf-layer switches, ensuring ultra-high bandwidth and low-latency connectivity across the data center.
The N9570-128QC features up to 128 high-speed 400G ports combined with redundant power supplies, fans, and control plane. Together, these form its high-availability architecture, ensuring extreme stability and uninterrupted service when the system operates under high load.
Powered by the NVIDIA Spectrum-4 high-performance chip, the N9570-128QC supports RoCEv2 lossless networking and full L2/L3 forwarding, delivering 1.6x higher AI networking performance, ultra-low latency, and reliability. Ideal for data centers, AI/ML clusters, HPC, and distributed storage, it combines standard Ethernet connectivity with performance isolation for mission-critical workloads.
Adaptive Routing (AR) intelligently balances traffic at the packet level across multipath networks, reducing latency, maximizing bandwidth utilization, and significantly boosting throughput. Its end-to-end optimization eliminates congestion bottlenecks, making it ideal for HPC, AI workloads, and other bandwidth-intensive environments.
The open-source SONiC network OS features hardware-agnostic design, enabling cross-vendor compatibility and seamless third-party integration via SNMP/RESTful APIs to meet diverse network needs. Backed by an active community, it efficiently addresses technical challenges for flexible management and stable operation.
By combining end-to-end adaptive RDMA routing and lossless networking technologies, N9570-128QC significantly enhances the effective bandwidth of the network, increasing it from 60% to 95%.
