32 QSFP-DD Open Source Mellanox Ethernet Switches 400GbE 1U MSN4700-WS2F

NVIDIA MSN4700-WS2F Spectrum-3 Based 400GbE 1U Open Ethernet Switch with Onyx 32 QSFPDD Ports 2 Power Supplies (AC) x86 CPU Standard Depth P2C Airflow Rail Kit

SN4700 Series Switches

The SN4700 spine/super-spine offers 32 ports of 400GbE in a compact 1U form factor. It enables connectivity to endpoints at varying speeds and carries a throughput of 25.6Tb/s, with a landmark 8.4Bpps processing capacity. As an ideal spine solution, the SN4700 allows maximum flexibility, with port speeds spanning from 1GbE to 400GbE per port.

Visibility

• NVIDIA What Just Happened (WJH) telemetry dramatically reduces mean time to issue resolution by providing answers to: When, What, Who, Where and Why
• Hardware-accelerated histograms track and summarize queue depths at submicrosecond granularity
• Inband Network Telemetry (INT)-ready hardware
• Streaming Telemetry
• 512K on-chip flow counters

Performance

• Fully shared packet buffer provides a fair, predictable and high bandwidth data path
• Consistent and low cut-through latency
• Intelligent hardware-accelerated data movement, congestion management & load balancing for RoCE & Machine learning applications that leverage NVIDIA GPUDirect
• Best-in-class VXLAN scale-10X more tunnels and tunnel endpoints
• 512K shared forwarding entries flexibly shared across ACL, LPM routes, host routes, MAC, ECMP and tunnel applications
• Up to 1M IPv4 route entries

Agility

• Comprehensive Layer-2, Layer-3 and RoCE
• Advanced network virtualization with high performance single pass VXLAN routing and IPv6 segment routing
• Cloud Scale NAT - 100K+ sessions
• Programmable pipeline that can programmatically parse, process and edit packets
• Deep Packet Inspection - 512B deep

Spectrum-3 provides deep and contextual network visibility, which enables network operators to proactively manage issues and reduce mean time to recovery/innocence.The WJH 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-3 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-3 features a unique feature rich and efficient packet processing pipeline that offers rich data center

network virtualization features without compromising on performance or scale. Spectrum-3 has a programmable pipeline and a deep packet parser/editor that can process payloads up to the first 512B. Spectrum-3 supports single pass VXLAN

routing as well as bridging. Additionally, Spectrum-3 supports advanced virtualization features such as IPv6 segment routing, and Network Address Translation (NAT).

The SN4000 series is part of the NVIDIA complete end-to-end solution which provides 1GbE through 400GbE interconnectivity within the data center. Other devices in this solution include ConnectX®-based network interface cards and LinkX® copper or

fiber cabling.
