Product Features
l High-Density Interfaces Line Cards
NSS18500 series provide maximum 288*100GE, 272*40GE, 384*10GE, 384*1GE interfaces and use an industry-leading crossbar architecture. The port combination fully satisfies the interface density requirement of data center and campus network scenarios.
l Highly Reliable Enterprise-class Hardware Design
NSS18500 has enterprise-class reliability and stability to ensure long-term service continuity. Redundant MPUs work in 1+1 hot backup mode. Redundant SFUs work in N+M hot backup mode. Redundant power supplies support work in N+M hot backup and also redundant fan trays design. The fan trays work in 1+1 backup mode to ensuring efficient heat dissipation.
l M-LAG for cross-device link aggregation
NSS18500 series support 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.
l VxLAN and EVPN for L2 Virtualized Deployment
NSS18500 series can work with the industry's mainstream virtualization platforms and acts a hardware gateway on a 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. NSS18500 series support BGP-EVPN, which is used as the overlay control plane and provides virtual connectivity between different layer 2/3 domains over an IP network.
l RoCEv2 Standard Compliance
NSS18500 series fully support the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. NSS18500 series 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.
l Southbound and Northbound API
NSS18500 series support NETCONF and RESTCONF API which can work with 3rd party SDN controller for simplified device remote configuration and management.
l Telemetry for intelligent OAM
NSS18500 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.
l Reliable hardware design and energy-saving
NSS18500 series use 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. NSS18500 series have energy-saving chipsets with EEE technology and can save system power consumption in real time.
l 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.
NSS18500 fully supports the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. NSS18500 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.
