The NVIDIA Spectrum™ SN5000 series of Ethernet switches is the fifth generation of NVIDIA Ethernet switches, purpose-built to accelerate data center fabrics. With port speeds spanning from 10 to 800 gigabits per second (Gb/s), the SN5000 series switches deliver accelerated Ethernet to every data center without compromising performance or feature set. The SN5000 series is ideal for enabling cloud-scale infrastructures for data centers of any size. SN5000 switch systems provide high performance, consistent low latency, and support for advanced data center networking features, making them ideal for cloud networks and end-to-end data center fabrics. Powered by the NVIDIA Spectrum-4 application-specific integrated circuit (ASIC), the SN5000 series features dynamic, flexible shared buffers and predictable performance. SN5000 switches are built to accelerate clouds and power NVIDIA platforms, including the NVIDIA Spectrum-X networking platform, NVIDIA EGX™, NVIDIA DGX™, NVIDIA HGX™, and NVIDIA OVX™, and AI software tools such as NVIDIA AI Enterprise and NVIDIA LaunchPad.
