With 128 fixed 400G ports, this switch is capable of handling large volumes of data, making it an ideal solution for large-scale data centers, artificial intelligence (AI) computing, and cloud service providers. The RG-S6990-128QC supports a broad range of networking protocols, offering flexible network design options. It also integrates advanced security measures and intelligent management functions, making it a robust, reliable, and scalable solution for modern networking needs.
This switch is built to ensure seamless performance for data-intensive applications, such as artificial intelligence training, machine learning, distributed storage, and high-performance computing (HPC). The RG-S6990-128QC provides unmatched performance in a compact 4U height chassis, supporting 128 ports of 400G and utilizing the latest load-balancing technology to optimize bandwidth use and reduce AI training time.
Product Features
High Port Density and Scalability
The RG-S6990-128QC provides exceptional scalability with 128 fixed 400G ports, which can be expanded to 256 ports at 200G. This feature makes it suitable for large network environments where future expansion and flexibility are required. Its compact form factor (4U) means that the switch offers high performance without taking up too much rack space, which is critical in large data centers where rack space is at a premium.
Advanced Routing Protocols
This switch supports a wide variety of IPv4 and IPv6 routing protocols, including static routing, RIPng, OSPFv3, and BGP4+. It offers flexibility for network architecture, making it possible to design and deploy networks according to specific needs. This includes capabilities for handling both IPv4 and IPv6 traffic at wire speed, ensuring high performance in dual-stack environments.
Intelligent Management Interfaces
The RG-S6990-128QC provides multiple management interfaces, including Console, MGMT port, and USB port. In addition, it supports SNMP v1/v2c/v3, Telnet, SSH, and other protocols for secure and efficient device management. With support for CLI command line and web-based management interfaces, administrators can monitor, configure, and troubleshoot the switch with ease.
Moreover, the switch supports ZTP (Zero Touch Provisioning), which simplifies network setup by automating device configuration. This feature drastically reduces the time and effort required to deploy and configure new switches, making it a highly efficient choice for large-scale data centers.
Quality of Service (QoS)
The RG-S6990-128QC ensures that critical network traffic is handled efficiently with its advanced Quality of Service (QoS) features. It supports multiple queue scheduling mechanisms, such as SP (Strict Priority), WRR (Weighted Round Robin), and DRR (Deficit Round Robin). These scheduling methods guarantee that high-priority traffic, such as voice and video, is transmitted ahead of less critical data.
Additionally, it incorporates congestion avoidance mechanisms like WRED (Weighted Random Early Detection) and tail drop, which help manage network congestion proactively and maintain optimal network performance.
Enhanced Reliability
Reliability is a key feature of the RG-S6990-128QC. The switch supports multiple high-availability technologies, including GR (Graceful Restart) for RIP, OSPF, and BGP protocols, as well as BFD (Bidirectional Forwarding Detection) for fast link failure detection. Additionally, the switch offers 2+2 power redundancy and 7+1 fan redundancy, ensuring that critical network operations can continue even in the event of hardware failures. All power supplies and fan modules are hot-swappable, minimizing downtime during maintenance.
Comprehensive Security Features
The switch provides robust security with support for RADIUS and TACACS+, two widely used network authentication protocols. It also supports ACL (Access Control List) filtering for both IPv4 and IPv6 traffic, which helps protect the network from unauthorized access and malicious attacks. Furthermore, the switch includes MD5 authentication for OSPF, RIP, and BGP protocols, adding another layer of security to routing traffic.
Telemetry and Network Monitoring
For network administrators who require real-time visibility into network performance, the RG-S6990-128QC offers comprehensive telemetry and monitoring features. It supports sFLOW (Sampled Flow), a high-precision network traffic monitoring tool that provides detailed traffic analytics. In addition, it supports SPAN, RSPAN, and ERSPAN for remote traffic monitoring and troubleshooting. These features allow administrators to quickly identify and resolve network issues, ensuring that the network operates at peak efficiency.
