·       Flexible Port Combination for Easy Expansion

The NSS5950-04C data center flexible modular switch supports high-density 1G/10G/25G/40G/100G ports and allows flexible combinations of various port types. The device can support up to 100*10G/25G ports, 64*40G ports, or 32*100G ports. This meets the high-speed interconnection demands of data centers, eliminates bandwidth bottlenecks, and supports network upgrades for the next 3 to 5 years.

·       Simplified and Flexible Network Deployment to Reduce Complexity

The NSS5950-04C enables easy deployment based on high-density access points and supports simplified network architecture, greatly enhancing access and aggregation capabilities while reducing the number of network layers and devices. This brings unprecedented convenience and efficiency to campus networks. Its high-performance and high-density features make it an ideal choice for aggregation and core layers in data centers, enabling box-to-box network architectures. Compared to traditional modular switch solutions, it significantly reduces network complexity and latency in data centers.

·       Supports RoCE for Building Zero-Jitter, Low-Latency Networks 

The NSS5950-04C core data center switch supports lossless Ethernet DCB (Data Center Bridging) technology, addressing packet loss issues due to congestion in traditional Ethernet networks. It provides a lossless, low-latency, and high-throughput network environment for RoCEv2 applications, meeting high-performance demands. Based on ECN (Explicit Congestion Notification), which is a congestion control technology, and using ETS (Enhanced Transmission Selection) for two-level scheduling, it controls the total data entering the network to prevent congestion. Combined with RoCE NICs, it enables end-to-end RoCE, increasing data transmission throughput, reducing network latency, and lowering CPU load. This helps create an end-to-end, zero-jitter, low-latency, lossless Ethernet network that meets the demands of cloud computing, big data, artificial intelligence, and high-performance computing deployments in data centers.

·       Integration and Openness with Exceptional Adaptability 

The NSS5950-04C offers exceptional adaptability for both data center and campus network scenarios.

In campus networks, it provides high-density interface access capabilities, delivering unmatched convenience and efficiency. In interconnection and dedicated line hubs, it offers a wide range of port options from 1GE to 100GE, ensuring smooth data traffic at high volumes. In integrated access zones, it efficiently supports seamless integration for security devices and various systems. In data centers, it provides robust performance for both aggregation and core layers, offering continuous power for network demands.

The NSS5950-04C is also highly open, seamlessly integrating into various converged infrastructure scenarios (storage/database/hyper-converged systems). It supports open platforms like ONIE (Open Network Install Environment) and Sonic (Software for Open Networking in the Cloud), empowering users to easily build more flexible, intelligent, and efficient data centers and campus networks based on cloud-native and open network architectures.
