- NVIDIA SN3420 25GbE Managed Switch – a versatile top-of-rack solution ideal for modern server and storage connectivity
- NVIDIA SN4700 400GbE Managed Switch – a high-performance 1U spine switch optimized for AI, HPC, and cloud-scale fabrics
- NVIDIA SN5400 400GbE Managed Switch - a high-performance 2U switch with double the ports of the SN4700
- NVIDIA SN5610 800GbE Managed Switch – an ultra-high-bandwidth platform enabling next-generation data center fabrics
Together, these systems provide a consistent architecture that enables organizations to build efficient, low-latency networks optimized for cloud, AI, and high-performance computing (HPC) workloads. With support for NVIDIA Cumulus Linux, these switches enable a Linux-based, open networking model that supports standards-based protocols and integrates seamlessly with existing automation frameworks and DevOps workflows.
By combining high throughput, low latency, and advanced telemetry with the operational simplicity of Linux-based networking, NVIDIA Spectrum switches empower IT teams to build agile, future-ready Ethernet fabrics that can efficiently support evolving application demands.
Did you know?
NVIDIA Spectrum Ethernet switches are not just high-performance networking platforms—they are engineered as part of a tightly integrated, end-to-end AI networking stack. NVIDIA Spectrum switches are designed in conjunction with NVIDIA SuperNICs, DPUs, and the Spectrum‑X architecture to optimize collective communication patterns common in AI and HPC workloads. This holistic approach enables more consistent latency, improved congestion control, and higher utilization across large-scale GPU clusters, helping organizations achieve faster time-to-insight and more predictable performance for distributed AI training and inference.
Ordering information
The following table lists the NVIDIA Ethernet switches orderable from Lenovo.
NVIDIA SN5600: The NVIDIA SN5600 800GbE switch is also currently available for ordering (model 7D5FCTONWW in oPSE airflow), however stock is limited. Contact your sales representative for more information. The SN5600 is not included in this product guide.

Lenovo EveryScale
Lenovo EveryScale is a framework for designing, manufacturing, integrating, and delivering data center solutions, with a focus on High Performance Computing (HPC), Technical Computing, and Artificial Intelligence (AI) environments.
With EveryScale, Lenovo pre-tests and validates a wide selection of Lenovo and third-party components, including NVIDIA Ethernet switches, to create a "Best Recipe" of components and firmware levels that work seamlessly together as a solution. From this testing, customers can be confident that these best-practice solutions run optimally for their workloads and are tailored to their specific needs.
Lenovo EveryScale hardware is pre-integrated, pre-cabled, and pre-loaded, optionally with an OS image, and is tested at the rack level during manufacturing. This process ensures reliable delivery and minimizes installation time in the customer data center.
With EveryScale, customers can focus their efforts on maximizing business value instead of consuming valuable resources to design, optimize, install, and support the infrastructure required to meet business demands.
