NVIDIA Spectrum MSN4600-CS2FC 64-Port 100GbE Open Networking Switch
1. Product Overview
The NVIDIA Spectrum MSN4600-CS2FC is a high-density 64-port 100GbE
open networking switch designed for modern data center spine and
leaf applications. This 2U network switch delivers exceptional
performance with 6.4Tb/s throughput and 8.4 billion packets per
second processing capacity. Featuring the advanced Spectrum-3 ASIC,
this switch provides complete flexibility with ports that can be
configured from 1GbE to 100GbE speeds, making it an ideal solution
for diverse data center environments.
2. Key Characteristics
- 64 x QSFP28 ports supporting 1/10/25/40/50/100GbE speeds
- 6.4Tb/s throughput capacity with 8.4Bpps processing performance
- 64MB fully shared dynamic packet buffer management
- Cut-through switching with consistent low latency
- Dual hot-swappable power supplies with 1+1 redundancy
- Pre-installed Cumulus Linux network operating system
- P2C (Port-to-Controller) airflow configuration
- Advanced hardware telemetry with WJH technology
3. Core Technologies
The MSN4600-CS2FC leverages NVIDIA's fourth-generation Spectrum-3
ASIC technology with support for advanced data center protocols
including VXLAN routing, EVPN, IPv6 segment routing, and RoCEv2. It
features a programmable pipeline, deep packet inspection (up to
512B), and hardware-accelerated telemetry for real-time network
visibility and analytics.
4. Operational Architecture
This high-performance network switch operates with cut-through
switching technology, minimizing latency by forwarding packets
immediately after destination address identification. The
innovative 64MB buffer architecture employs dynamic memory
allocation that automatically directs resources to congested ports,
preventing packet loss and ensuring equitable bandwidth
distribution across all 64 ports. The Spectrum-3 ASIC provides
predictable performance regardless of packet size or traffic
pattern.
5. Applications & Deployment Scenarios
Ideal for enterprise data centers, cloud service providers, and
high-performance computing environments. The MSN4600-CS2FC network
switch is optimally deployed as:
- Spine layer switch in large-scale leaf-spine architectures
- Core distribution switch for cloud and enterprise networks
- High-density aggregation switch for storage and data analytics
- Fabric backbone for hyper-converged infrastructure deployments
- High-performance interconnect for AI/ML and GPU computing clusters
