2. Product Overview (Full English)

The Huawei CloudEngine CE8851-32CQ8DQ-K is a next-generation, high-performance, high-density data center Ethernet switch from Huawei’s CloudEngine 8800 series. Designed for cloud-oriented data center networks and high-end campus networks, the CE8851-32CQ8DQ-K delivers a combination of high performance, low latency, and extensive port density to meet the demanding requirements of modern data center environments.

High-density port configuration – The switch provides 32× 100GE QSFP28 ports (also operable as 32× 200GE QSFP56 ports) and 8× 400GE QSFP-DD ports. The 100GE and 200GE ports are backward compatible with 40GE, with 100GE ports supporting breakout into 4×25GE, 4×10GE, or 2×50GE. The 400GE QSFP-DD ports support breakout into 4×100GE, providing flexible and scalable networking capabilities.

Key capabilities of the CE8851-32CQ8DQ-K include:

High switching capacity – Up to 25.6 Tbps switching capacity with 7200 Mpps L2/L3 wire-speed forwarding performance
Extensive data center features – Full support for Software-Defined Networking (SDN) capabilities, VXLAN hardware gateway functionality, and BGP-EVPN as the VXLAN control plane
High network reliability – Supports M-LAG (Multichassis Link Aggregation Group) for device-level link reliability, independent node upgrades with zero service interruption, and M-Lag Lite for server active-active access
Intelligent automation and open integration – Supports NetConf protocol for integration with Huawei iMaster NCE-Fabric, Ansible automation management, and deep integration with mainstream cloud platforms (both commercial and open-source) via Open API
Flexible airflow design – Supports both front-to-back and back-to-front airflow with 6 hot-swappable fan modules

The CE8851-32CQ8DQ-K employs advanced hardware architecture and a 1U chassis design, delivering high-density 400GE/200GE/100GE/40GE/25GE/10GE ports. It can interoperate with Huawei CloudEngine 16800 or CloudEngine 12800 series core switches to build elastic, virtualized, and high-quality 400GE/100GE full-mesh networks for cloud computing data centers. The switch can function as a core or aggregation switch in data center networks, helping enterprises and carriers build scalable data center network platforms for the cloud computing era.
