Nvidia Spectrum-2 SN3420 - Introduction

NVIDIA Spectrum-2 SN3000 1U and 2U Switch Systems Hardware User Manual 8
Introduction
NVIDIA SN3000 series switches are the third generation of NVIDIA Spectrum purpose-
built switches for leaf/spine and super-spine datacenter applications. Allowing maximum
exibility, SN3000 series provides port speeds spanning from 1GbE to 200GbE, and a port
density that enables full rack connectivity to any server at any speed. In addition, the
uplink ports allow a variety of blocking ratios to suit any application requirement. This
series is ideal for building wire-speed and cloud-scale layer-2 and layer-3 networks.
SN3000 platforms deliver high performance, consistent low latency along with support
for advanced software dened networking features, making it the ideal choice for web
scale IT, cloud, hyperconverged storage and data analytics applications.
Open Ethernet breaks the paradigm of traditional switch systems, eliminating vendor
lock-in. Instead of forcing network operators to use the specic software that is provided
by the switch vendor, Open Ethernet oers the exibility to use a choice of operating
systems on top of Ethernet switches, thereby re-gaining control of the network, and
optimizing utilization, eciency and overall return on investment. Open Ethernet adopts
the same principles as standard open solutions for servers and storage, and applies them
to the world of networking infrastructure. It encourages an ecosystem of open source,
standard network solutions. These solutions can then be easily deployed into the modern
data center across network equipment that eases management and ensures full
interoperability. With a range of system form factors, and a rich software ecosystem, the
SN3000 series allows you to pick and choose the right components for your data center.
NVIDIA SN3000 series platforms are based on the high-performance 50G PAM4 capable
NVIDIA Spectrum-2 ASIC. SN3000 platforms are available in a range of congurations,
each delivering high performance combined with feature-rich layer 2 and layer 3
forwarding, ideally suited for both top-of-rack leaf and xed conguration spines. The
NVIDIA SN3000 series provides full wire speed, cut through-mode latency, on-chip fully-
shared 42MB packet buering, and exible 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 SN3000 series is capable of
addressing today’s data center’s complex networking requirements, growth and
expansion.
As data-center switching architectures increasingly adopt 100GbE, the SN3420 system
oers a high performance, cost-eective way to evolve host connectivity from 10G to
25G. Equipped with 48 ports of 10/25GbE and 12 ports of up to 100GbE in a compact 1U
form factor, the SN3420 is an ideal Top-of-Rack (ToR) switch platform, delivering a total
throughput of up to 4.8Tb/s with a processing capacity of 3.58Bpps. The SN3420 enables
