NSS5932 Series Data Center RoCE Switch

NSS5932 series switches are Maipu new generation 25GE data center RoCE switches designed for enterprise data center networks, providing high-throughput, high-density interfaces, larger buffer and lower latency. The NSS5932 series adopts advanced hardware architecture with 48*25GE access ports and 8*40/100GE uplinks. By using Maipu MyPowerOS software platform, NSS5932 series provide rich data center service features and management capability.

NSS5932 series realize large buffer of the interfaces, meeting the burst flow forwarding without packet loss, provide the M-LAG technology for virtualization scenarios, provide the modular power and fan design for high reliability. The key components adopt "overvoltage" designs to ensure that the product has the strong ability of continuous operation. NSS5932 series can work with NSS5950 & NSS18500 spine switches to build a complete, scalable, virtualized RoCEv2 fabric network that meets the data center requirements.

NSS5932-48FP8QS supports 48*10/25G SFP28 optical interfaces, 8*40/100G QSFP28 optical interfaces, five modular fan slots, one modular multi-function slot and dual modular power slots.

Product Features

· High-density 25GE Ports with 100GE Uplinks

NSS5932 series provide fixed 48*25GE interfaces in compact 1U device. The port combination fully satisfies the interface density requirement of data center scenarios. NSS5932 series have a maximum of 8*100GE QSFP28 uplinks, the uplink ports can be connected to NSS5950 & NSS18500 spine switches to build a non-blocking DC network architecture.

· RoCEv2 Standard Compliance

NSS5932 series fully support the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. The NSS5932 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

NSS5932 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.

· VxLAN and EVPN for L2 Virtualized Deployment

NSS5932 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. NSS5932 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.

· Telemetry for Intelligent OAM

NSS5932 series provide 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

NSS5932 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.

· 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.

NSS5932 series fully support the RoCEv2 standards, meeting the requirements for switch performance in high-performance data center scenarios. The NSS5932 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.
