Introduction

Key Specifications

1、Network Performance

  • Ports: 36 × QSFP28 ports supporting EDR 100Gb/s InfiniBand (backward compatible with FDR 56Gb/s and QDR 40Gb/s) 
  • Throughput: 7.2Tb/s aggregate switching capacity (non-blocking architecture)  
  • Latency: 90ns switching delay – ideal for latency-sensitive applications

2、Hardware Design

  • Form Factor: 1U rack-mountable (43.6mm H × 428mm W × 685.8mm D) 
  • Redundancy:
    • Power: 1+1 redundant hot-swappable 80+ Gold/Energy Star-certified PSUs 
    • Cooling: N+1 redundant hot-swappable fans  
  • Power Efficiency: 122W typical power consumption (ATIS weighted) 

3、Advanced Technologies

  • SHARP (Scalable Hierarchical Aggregation Protocol): Accelerates collective communications (e.g., MPI/OpenSHMEM) by offloading operations to switch hardware, reducing CPU overhead by 30%+  
  • Adaptive Routing: Dynamically balances traffic across SlimFly/Dragonfly+ topologies 
  • VL2VL Mapping: Enables QoS prioritization for critical workloads
