Core Features & Differentiators
-
Modular Line-Card Flexibility
Chassis accept 100 GE, 200 GE, or 400 GE line cards, enabling mix-and-match deployments per pod or rack requirements. -
Massive Fabric Capacity
Switch fabrics range from 19.2 Tbps to 25.6 Tbps, with forwarding up to 8,000 Mpps—ensuring non-blocking performance for east-west traffic. -
400 GE Spine Connectivity
Eight QSFP-DD uplinks per chassis deliver 400 GE (or fallback to 100 GE), ideal for spine-leaf or multi-pod architectures. -
Carrier-Grade Resilience
Hot-swap PSUs and fans, dual-bank firmware, and VSU clustering provide sub-200 ms failover and uninterrupted operation. -
Comprehensive L2/L3 & Overlay
Full support for VLANs, STP/MSTP, ERPS, OSPF v2/v3, BGP, IS-IS, VRRP, VXLAN, and EVPN—accelerating fabric virtualization and multi-tenant isolation. -
High-Performance Silicon
Purpose-built ASICs with large on-chip buffers (>64 MB) minimize latency and packet loss under congestion. -
Unified Management & Analytics
RGOS 12.X offers consistent CLI, GUI, SNMPv3, sFlow, NetStream, and RESTful APIs for automated orchestration.
Deployment Scenarios
A. Spine-Leaf Data Center Fabric
Use RG-S6920-4C or RG-S6930-2C as spine, aggregating leaf switches with 400 GE uplinks to sustain massive east-west flows.
B. High-Density Leaf Node
Deploy RG-S6910-3C or RG-S6920-4C as leaf switches, connecting servers via 100 GE or 200 GE ports and uplinking to spine chassis.
C. Campus Core Switch
Combine S6900 series with S6500/S6000 switches in VSU clusters for campus backbones requiring both 100 GE and 400 GE fabrics.
D. AI/HPC Clusters
Capitalize on zero-loss Ethernet (PFC & ECN) and high throughput to support machine-learning training and high-performance compute clusters.
E. Service Provider Edge
Integrate S6900 spine switches at edge PoPs for carrier networks, leveraging advanced routing, MPLS, and segment routing capabilities.
Deployment & Management Experience
- Zero-Touch Provisioning: Ruijie INC automates device discovery and template rollout at scale.
- Hot-Swap Hardware: PSUs, fans, and line cards replaceable under power; dual-bank firmware ensures in-service upgrades.
- Centralized RGOS: CLI, web GUI, SNMPv3, SSH, Telnet, and open APIs streamline multi-chassis operations.
- Deep Telemetry: sFlow, NetStream, and RMON provide real-time visibility into traffic and health metrics.

FAQ – Practical Insights
Q1: Which chassis supports 200 GE ports?
RG-S6930-2C accommodates 72×200 GE ports via two line cards; S6910-3C and S6920-4C support 200 GE through mix-and-match modules.
Q2: Can uplinks auto-negotiate between 100 GE and 400 GE?
Yes—QSFP-DD ports detect and configure either speed automatically.
Q3: Is VSU stacking possible across S65xx and S69xx series?
Absolutely—VSU spans heterogeneous chassis running compatible RGOS versions.
Q4: How is lossless Ethernet achieved?
Priority Flow Control (PFC) and Explicit Congestion Notification (ECN) ensure zero packet loss for storage and HPC traffic.
Q5: What routing protocols are supported?
Full suite: Static, RIP, OSPF v2/v3, IS-IS, BGP, and VRRP for high-availability core operations.
Conclusion
The Ruijie S6900 Series—spanning S6910, S6920, and S6930 chassis—delivers a future-proof platform for Data Center Switch, Spine Switch, and core Switch deployments.
With flexible 100/200 GE access, 400 GE uplinks, massive 16–25 Tbps fabrics, and advanced RGOS features, it stands as the go-to 100GE Switch and 400GE Switch solution for next-gen networks.
