Product Features
· 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.
· RoCEv2 Standard Compliance
NSS5950-04C fully support the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. The NSS5950-04C supports a wide range of lossless Ethernet technologies, including PFC, ECN, ETS, DCBX, etc. 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.
· M-LAG for Cross-device Link Aggregation
NSS5950-04C supports multi-chassis link aggregation group (M-LAG), which enables links of multiple switches to aggregate into one to implement cross-device link backup. The rest of switches in the M-LAG group are working actively regardless any switch failure. During the upgrade, other switches in the system take over traffic forwarding to ensure uninterrupted services.
· VxLAN and EVPN for L2 Virtualized Deployment
NSS5950-04C series can work with the industry's mainstream virtualization platforms and acts a hardware gateway on an VxLAN overlay network. Virtual extensible LANs (VxLAN), a common network virtualization overlay protocol that expands the layer 2 network address space from 4,000 to 16 million. NSS5950-04C supports BGP-EVPN, which is used as the overlay control plane and provides virtual connectivity between different layer 2/3 domains over an IP network.
· Southbound and Northbound API
NSS5950-04C supports NETCONF and RESTCONF API which can work with 3rd party SDN controller for simplified device remote configuration and management.
· Telemetry for Intelligent OAM
NSS5950-04C provides telemetry technology to collect device data in real time and send the management data to customer network analyzer platform. Telemetry systems, done properly, play an important role in providing you with information about the health of your network, so you can respond intelligently to prevent hardware failure and network downtime. It can help customers to identify and analyze network problems which affect user experience.
· Reliable Hardware Design
NSS5950-04C uses a standard airflow design which isolates cold air channels from hot air channels. This design improves heat dissipation efficiency and meets design requirements of data center. It adopts hot swap redundant power modules and fans which ensure hardware reliability and non-stopping operation. The fan speed can be adjusted dynamically based on system workload.
· Free Licensing Policy
Maipu always insists on “One-time investment” free license policy, the standard features and advanced features will be never divided to different version. For any new firmware version, Maipu will share to customers without extra charge. Compared with other manufacturers, Maipu free license policy can better protect users' short-term and long-term investment.

Typical Application
RoCEv2 Lossless Ethernet Solution for Data Center
RoCEv2 is a network protocol that enables servers in data centers to perform Remote Direct Memory Access (RDMA) directly over Ethernet. RoCEv2 benefits significantly from a lossless Ethernet environment because it relies on high reliability and low latency for performance efficiency. Lossless Ethernet technology ensures that RoCEv2 can deliver its full potential benefits by avoiding the typical challenges associated with standard Ethernet communications.
NSS5950-04C fully supports the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. NSS5950-04C supports a wide range of lossless Ethernet technologies, including ETS, PFC, ECN, DCBX, etc. 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.
