Introduction
The NVIDIA Spectrum SN5000 series switches are the 5th generation of Spectrum
switches, purpose-built to accelerate data center fabrics. The SN5000 series provides port
speeds spanning from 40GbE to 800GbE, and delivers accelerated Ethernet to every data
center. The SN5000 series is ideal for enabling cloud-scale infrastructure for data centers
of any size. The SN5000 switch systems provide high performance and consistent low
latency along with support for advanced software defined networking features, making
them the ideal choice for AI, cloud, data analytics, and simulation applications.
Powered by NVIDIA Spectrum-4 ASICs, the SN5000 series features dynamic, flexible
shared buffers and predictable wire speed performance. The SN5000 is built to
accelerate NVIDIA platforms, including NVIDIA EGXTM, NVIDIA DGX PODTM , and NVIDIA
OVXTM SuperPODs, and AI solution stacks such as NVIDIA AI Enterprise and NVIDIA
LaunchPad. As part of the Spectrum platform, the SN5000 systems are pre-tested and
pre-validated with NVIDIA’s full portfolio of Ethernet networking technology, including
BlueField DPUs, ConnectX SmartNICs, and LinkX interconnects. This end-to-end switch to
host solution is critical to powering accelerated workloads, and delivers the high
performance and innovative feature set needed to supercharge cloud-native applications
at scale.
SN5000 switch systems are based on the high-performance Spectrum-4 ASIC with a
bidirectional switching capacity of up to 51.2 Tbps. SN5000 platforms are available in a
range of configurations, each delivering high performance combined with feature-rich
layer 2 and layer 3 forwarding, ideally suited for both top-of-rack leaf and fixed
configuration spines. SN5000 series provides full wire speed, cut through-mode latency,
on-chip fully-shared 128MB packet buffering, and flexible port use in addition to
advanced capabilities. Combining a wide range of innovations in the area of
programmability, telemetry, and tunneling with industry-leading performance, NVIDIA
SN5000 series is capable of addressing the complex networking requirements of today’s
data centers.
The SN5400 smart spine/super-spine offers 64 ports of 400GbE in a dense 2U form
factor, fully splittable to up to 128 ports of 200GbE/40GbE, and up to 256 ports of
10/25/50/100GbE when used with splitter cables.
