Product Features
· High-density 400G Ports
The NSS7816-32QE adopts advanced hardware architecture with full 32*400G interfaces in compact 1U device. The port combination fully satisfies the interface density requirement of data center scenarios.
· RoCEv2 Lossless Ethernet Technology
The NSS7816-32QE supports lossless Ethernet (RoCEv2) features such as Priority-based Flow Control (PFC) and Explicit Congestion Notification (ECN) control algorithms which can avoid packet loss and message retransmission that may occur in traditional Ethernet protocols when encountering network congestion, reduce network latency and jitter, and thus achieve higher performance and lower latency.
· M-LAG for Cross-device Link Aggregation
The NSS7816-32QE 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 for Layer2/3 Virtualized Deployment
The NSS7816-32QE 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. NSS7830-09C supports BGP-EVPN, which is used as the overlay control plane and provides virtual connectivity between different layer 2/3 domains over an IP or MPLS network.
· Telemetry for Intelligent OAM
The NSS7816-32QE 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.
· Netconf & Restfonf API Integration
The NSS7816-32QE supports NETCONF and Restconf API and can work with 3rd party SDN controller for simplified device remote configuration.
· Reliable Hardware Design
The NSS7816-32QE 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 t8ypical challenges associated with standard Ethernet communications.
NSS7816 series fully support the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. The NSS7816 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.
