Product Overview #

The RG-S6990-128QC2XS is a state-of-the-art modular switch designed specifically for high-end data centers and advanced AIGC (Artificial Intelligence Generated Content) intelligent computing environments. This switch is engineered with an impressive hardware architecture featuring 128 400GE ports and 2 10GE ports, all capable of supporting line-speed data forwarding. It boasts robust redundancy with hot-swappable power supplies and fans, ensuring uninterrupted operation. Moreover, it integrates AI-Fabric solutions alongside RALB (Real-time Adaptive Load Balancing) and AILB (Adaptive Intelligent Load Balancing) technologies, enhancing bandwidth efficiency and significantly reducing the training time required for AI models. In typical configurations, it can support clusters of up to 8,000 cards in a two-level network and up to 100,000 cards in a three-level network. The switch also enables quick deployment of RoCE (RDMA over Converged Ethernet) configurations, streamlining complex setups such as ECN (Explicit Congestion Notification) and PFC (Priority Flow Control) for RDMA networks.

Product Features #

• Next-Generation Data Center Networking: The increasing demands of AI machine learning, big data, and high-performance computing necessitate advancements in data center networking towards 200G/400G capabilities. The RG-S6990-128QC2XS meets these demands with a staggering configuration of up to 128 400G ports and 2 10G ports in a compact 4U chassis.
• High Performance with Low Latency: This switch, combined with the RG-S6580 series, utilizes advanced PFC and ECN flow control technologies, alongside optimized MMU (Memory Management Unit) settings, to establish a lossless and low-latency RDMA network. By employing RALB and AILB, the RG-S6990-128QC2XS effectively enhances bandwidth and minimizes AI training durations.
• Telecom-Level Reliability: Engineered for high availability, the switch features dual power supply redundancy (2+2) and fan redundancy (4+1), with all modules designed for hot-swapping without service interruption. It includes sophisticated fault detection capabilities for both power supplies and fans, automatically adjusting fan speeds in response to temperature changes.
• Rapid Deployment: The RG-S6990-128QC2XS simplifies the deployment process through automatic configuration of network parameters and template-based setups. This efficiency dramatically reduces project timelines, while built-in acceptance testing guarantees quality through comprehensive testing of cables, optical modules, and devices.
• Intelligent Maintenance Solutions: With features like AI-driven ECN tuning and real-time telemetry for key ROCE network metrics, the switch offers visibility into end-system statuses and congestion, facilitating proactive maintenance.
• Support for IPv4/IPv6 Dual-Stack Protocols: The hardware is designed to accommodate both IPv4 and IPv6 protocols, providing flexibility in communication strategies and a diverse range of routing protocols.
• Comprehensive Device Management: The RG-S6990-128QC2XS supports multiple management interfaces—including Console, MGMT, and USB—while also offering management through SNMP, CLI, and Telnet, ensuring secure and straightforward device administration.
