Huawei Digital Power

CloudEngine 16800 Series

CloudEngine16800 Series, now upgraded with the CE16800-X, is Huawei’s flagship core switch for large-scale, AI-driven, and high-performance data centers. Designed for intelligent computing, cross-region scheduling, and the evolving needs of data traffic in cloud environments, it supports massive bandwidth, zero packet loss, and intelligent network management.


Key Highlights


Massive Capacity

  •  Up to 173 Tbps / 1548 Tbpsswitching capacity

  • Smooth evolution to 400GE to support future traffic demand

Intelligent Performance

  • iLosslessalgorithm enables real-time traffic learning and dynamic optimization

  • Zero packet loss for full-throughput forwarding and stable supercomputing environments

Smart Operations & Maintenance

  • Telemetry-based millisecond data collection

  • Faults located in under 3 minutes

  • Predicts up to 90% of network risks proactively

Unified Network Architecture

  • Supports Huawei’s hyper-converged Ethernet for computing, storage, and HPC network unification

  • Reduces TCO by consolidating traditionally separate networks
