Key selling points

1. 400G Ultra-High Density, Flexible Splitting

Integrates 32x400GE QSFP-DD ports in a 2U space, with a maximum support of 128x100GE per device, meeting the ultra-high bandwidth requirements of AI clusters, supercomputing, and distributed storage.

The 400GE ports can be split into 4x100GE or 2x200GE, flexibly adapting to access and aggregation layer networking.

2. Non-blocking Full Line-Speed, Low Latency, Large Buffer

Non-blocking switching architecture ensures line-speed forwarding on all ports, eliminating bandwidth bottlenecks.

Hardware-level low-latency forwarding + 65MB large buffer adapts to high-frequency transactions, real-time computing, and RoCEv2 lossless traffic.

3. iLossless Intelligent Lossless, Adaptable to AI/Storage

Supports the iLossless intelligent lossless algorithm, providing a "no packet loss, low latency, high throughput" network environment for RDMA/RoCEv2 traffic.

Supports lossless data center features such as PFC, ECN, and DCQCN, ensuring stable operation of AI training and distributed storage.

4. Cloud Computing Full-Scenario Features

Supports VXLAN, EVPN, SRv6, SDN, Telemetry, and INT in-path detection.

Improves IPv6, multicast, security, QoS, and traffic visualization, adapting to cloud-native and intelligent computing networks.

5. High Reliability, Easy Operation and Maintenance, Green Energy Saving

Dual power supplies + dual fan redundancy, supporting hot-swapping, BFD, and ISSU non-disruptive upgrades.

Supports M-LAG, stacking, and cross-device link aggregation, enhancing network resilience.

Intelligent fan speed control and low-power chips create a green and low-carbon data center.
