Ethernet switches are an often forgot about component of an HPC cluster, especially when there is a secondary high speed networking included.

However, choosing the right Ethernet switch is an essential component of a cluster as it is often used for management, monitoring, and other access. Aspen Systems can help you choose the right Ethernet switches, whether they will be for Top of Rack (TOR) or for other needs.

NVIDIA is the world’s leading provider of open networking for all tiers of hardware and software.

NVIDIA Spectrum® switches are based on industry-leading application-specific integrated circuit (ASIC) technology and provide a wide variety of modern network operating system choices, such as Cumulus® Linux, SONiC, and NVIDIA Onyx®.


NVIDIA Spectrum Ethernet Switch offers a broad portfolio of top-of-rack and aggregation switches. Implement in your layer-2 and layer-3 cloud designs, in overlay-based virtual networks, or within mission-critical, high-performance ethernet storage fabrics. In any deployment, you’ll get:

  • Industry-leading performance and predictability
  • Comprehensive visibility
  • High-performance remote direct-memory access over converged ethernet (RoCE) Advanced virtualization


Open networking is about removing constraints while providing choice and flexibility, which means all tiers must be open. NVIDIA is a leader in end-to-end open networking across all layers of software and hardware.

  • NVIDIA networking features, from adapters to switches to data processing units (DPUs), can all be accessed and managed through open interfaces. Additionally, NVIDIA has contributed heavily to projects like SONiC, Data Plane Developers Kit (DPDK), and Free Range Routing (FRR).
  • Spectrum programmable ASICs provide flexibility to handle evolving networking technologies, including new protocols that may emerge in the future.
  • Since NVIDIA doesn’t restrict usage or programming of the ASIC, Spectrum’s Open SDK API helps the Ethernet community create open-source networking applications and protocols much faster.
