Description

Product Overview

The RG-S6920-4C switch represents a new generation of high-performance, high-density modular switches developed by Ruijie Networks. It is designed specifically for high-end data centers and AIGC intelligent computing scenarios.

This switch features an advanced hardware architecture that allows for a maximum of 32 400GE or 128 100GE ports, all capable of line-speed forwarding. Additionally, it supports redundant pluggable power supplies and fans. The RG-S6920-4C also integrates Ruijie’s AI-Fabric solution, which includes RALB and AILB load balancing technologies. This enhances bandwidth for AIGC intelligent computing applications and shortens AI training durations. In typical secondary network configurations, it can support up to 512 400G ports, while in tertiary configurations, it can handle up to 2000 400G ports. The switch also features one-click deployment for RoCE configurations, facilitating quick setups for complex RDMA network configurations such as ECN and PFC.

Product Features

Building Next-Generation Data Center Networks

The rapid advancement of applications like AI and machine learning is propelling the evolution of next-generation data center networks toward 100G and 400G. These networks necessitate devices with higher performance and greater bandwidth within constrained physical spaces. The RG-S6920-4C can provide:

• Up to 128 100G ports,
• A combination of 64 100G ports plus 16 400G ports,
• Or 32 400G ports,
  effectively meeting the demands of modern data center networks.

High-Performance, Low-Latency Data Center Network

When paired with the RG-S6510 series switches, the RG-S6920-4C can establish an end-to-end, lossless, low-latency RDMA (Remote Direct Memory Access) network using technologies such as PFC/ECN and MMU optimization. It supports Ruijie’s AI-Fabric solutions, including RALB and AILB load balancing, resolving ECMP conflicts caused by traditional flow-based load sharing. This significantly enhances bandwidth for AIGC applications and reduces AI training times, fulfilling network deployment requirements for AI/machine learning, high-performance computing, and distributed storage.

Telecom-Level Reliability Protection

The RG-S6920-4C is designed with reliability in mind, featuring:

• 2+2 power redundancy and 5+1 fan redundancy,
• Hot-swappable power and fan modules, allowing for maintenance without disruption,
• Fault detection and alarms for power and fans, with automatic speed adjustments based on temperature variations to better suit data center conditions.

The switch also includes multiple reliability protections at both the device and link levels, using over-current, over-voltage, and over-temperature protection technologies. It supports various link reliability techniques such as GR fast restart and BFD fast forwarding detection, which help mitigate the impact of anomalies on network services during periods of high traffic.

Rapid Deployment

This switch supports automatic configuration of network parameters and template imports, significantly speeding up project deployment times. It includes automatic acceptance testing for cables, optical modules, and devices, ensuring high quality upon delivery.

Intelligent Operation and Maintenance

The RG-S6920-4C supports:

• AI-driven automatic parameter adjustments,
• Real-time telemetry for key RoCE network indicators,
• Visualization of side-state and RoCE services, as well as congestion and packet loss analysis.

IPv4/IPv6 Dual-Stack Protocol Multi-Layer Switching

The RG-S6920-4C switch supports hardware-based multi-layer line-speed switching for both IPv4 and IPv6 dual protocol stacks. It distinguishes and processes both IPv4 and IPv6 protocol packets and supports various tunneling technologies, providing flexible inter-network communication solutions that align with the demands of IPv6 networks. It supports a variety of IPv4 routing protocols, including static routing, RIP, OSPF, IS-IS, and BGP4, accommodating diverse network environments. For IPv6, supported routing protocols include static routing, RIPng, OSPFv3, and BGP4+, allowing for flexibility whether upgrading existing networks to IPv6 or establishing new IPv6 networks.

Comprehensive Manageability

The RG-S6920-4C offers rich management interfaces, including:

• Console, MGMT, and USB ports,
• Support for SNMPv1/v2c/v3 and general network management platforms.

CLI commands, Telnet, and cluster management enhance device management convenience, with robust security measures such as SSH2.0 and SSL for secure management. The switch supports SPAN/RSPAN mirroring and multiple mirrored observation ports, enabling effective analysis of network traffic output for timely management and maintenance. This visibility helps users optimize network structure and adjust resource allocation as needed.
