N9520O-64OC, 64x 800Gb OSFP and 2x25G SFP28, Broadcom Tomahawk 5 51.2Tbps, ONIE Preinstalled, for AI/ML/Cloud/HPC
With the flexible upgrade Open Network Install Environment (ONIE), the NADDOD switch is specifically engineered to meet the most demanding AIDC network requirements. It supports up to 8,192 400G NIC ports in a two-tier Leaf-Spine architecture, while accommodating a comprehensive range of optical and copper connectivity options—including DAC, ACC, AEC, and 800Gbase-SR8/DR8/FR8 transceivers. This significantly enhances network scalability, improves deployment flexibility, and dramatically reduces Total Cost of Ownership (TCO). Moreover, by leveraging the inherent agility and high-performance architecture of Naddod OS, it provides unparalleled network support for AI workloads.
In AIDC network architecture design, cost-effectiveness and operational efficiency are critical considerations. By implementing an advanced two-tier Leaf-Spine architecture, the NADDOD 51.2T switch can remarkably interconnect 8,192 400G NIC ports. This enables the construction of unprecedented ultra-large-scale networks with significantly fewer devices, thereby:
Dramatically reducing network costs:
Decrease the demand for expensive optical modules and cables, while reducing rack space and energy consumption.
Optimizing operational efficiency:
Significantly simplify the network topology structure, reduce the complexity of troubleshooting, and release valuable IT resources.
Broadcom Tomahawk 5 delivers breakthrough network performance for AI/ML workloads with its ultra-high bandwidth of 51.2 Tb/s, 5 nm process technology, monolithic architecture, and shared buffer design.
The NADDOD N9500 switch platform delivers comprehensive RoCEv2 support with ultra-low latency and near-zero CPU overhead. Combined with congestion control mechanisms such as PFC and ECN , it enables lossless network infrastructure.
The NADDOD N9500 switch platform is optimized for AI/ML/HPC workloads, featuring Dynamic Load Balancing for efficient and resilient path selection.
