NVIDIA MSN3420-CB2F Spectrum-2 Based 25GbE/100GbE 1U Open Ethernet Switch with Onyx 48 SFP28 Ports and 12 QSFP28 Ports 2 Power Supplies (AC) x86 CPU Short Depth P2C Airflow Rail Kit
SN3420 Series Switches
As data-center switching architectures increasingly adopt 100GbE, the SN3420 offers a high-performance, cost-effective 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) network switch, delivering a total throughput of up to 4.8Tb/s with a processing capacity of 3.58Bpps. The SN3420 enables the seamless use of QSFP28 connections for leaf-spine topology and future-proofing the data center.Visibility

Packet buffer architecture has a major impact on overall switch performance. The Spectrum-2 packet buffer is fully shared across all ports, supporting cut through line rate traffic from all ports, without compromising scale or features. With its fast packet buffer, Spectrum-2 is able to provide a high-performance fair and bottleneck-free data path for mission-critical applications.
Spectrum-2 provides deep and contextual network visibility, which enables network operators to proactively manage issues and reduce mean time to recovery/innocence. The What Just Happened (WJH) Spectrum feature leverages the underlying silicon and software capability to provide granular and event-triggered information about infrastructure issues. In addition, the
rich telemetry information from Spectrum-2 is readily available via open APIs that are integratable with third party software tools and workflow engines.
For modern data center infrastructure to be software defined and agile, both its compute and network building blocks need to be agile. Spectrum-2 features a unique feature rich and efficient packet processing pipeline that offers data center network virtualization features without compromising on performance or scale. Spectrum-2 is a programmable pipeline and a deep
packet parser/editor (can process payload up to the first 512B). Spectrum-2 supports single pass VXLAN routing as well as bridging. Additionally, Spectrum-2 supports advanced virtualization features such as IPv6 segment routing, and network address translation (NAT).
