Huawei CloudEngine CE16804-DC – Data Center Switch

Product Overview

The Huawei CloudEngine CE16804-DC is a high-performance modular chassis switch belonging to the CloudEngine 16800 Series, designed for data center core, cloud computing infrastructure, and large-scale enterprise backbone networks. As part of Huawei’s next-generation modular switching platform, it features an innovative backplane-free Clos architecture with cell switching and Virtual Output Queue (VoQ) technology, delivering high throughput, low latency, and exceptional scalability.

The switch chassis is 9.8U high and features a 4-slot architecture with service slots supporting flexible combinations of line processing units (LPUs). It includes 2 main processing unit (MPU) slots for 1:1 redundancy and up to 9 switching fabric unit (SFU) slots (6 factory-configured, scalable to 9 for future expansion). The CE16804-DC is specifically designed for -48V / -60V DC power environments commonly found in telecommunications facilities and data centers with DC power infrastructure. It supports up to 6 power modules with a recommended N+1 redundant power architecture (5+1 backup recommended for dual-input power supply systems). The chassis adopts a strict front-to-back airflow design, optimized for hot aisle/cold aisle data center layouts.

The CE16804-DC supports high-speed Ethernet evolution including 100GE, 200GE, and 400GE, enabling flexible data center expansion and seamless network scalability. It is widely deployed in spine-leaf architectures, hyperscale cloud platforms, high-performance computing environments, and telecom carrier-grade networks. The system integrates intelligent traffic management, carrier-grade redundancy design, and modular expansion capabilities, making it a critical foundation for next-generation network infrastructure.

Key differentiators of the CE16804-DC include its high-density modular architecture with up to 387 Tbit/s switching capacity, the innovative iLossless intelligent algorithm for zero packet loss and end-to-end microsecond-level latency, comprehensive VXLAN routing and bridging with BGP-EVPN support, M-LAG for cross-device link aggregation with active-active load sharing, millisecond-level Telemetry data collection for intelligent O&M, and support for IEEE 1588v2 (PTP) for time-synchronized networks.

The chassis is supplied without power modules and fan modules, which must be ordered separately.
