Huawei CloudEngine 6863-48S6CQ Data Center Switch

The Huawei CloudEngine 6863-48S6CQ (CE6863-48S6CQ) is a high-density 25GE/100GE leaf switch purpose-built for modern data center spine-leaf architectures and AI/ML training fabric deployments. It provides 48 × 25GE SFP28 downlink ports and 6 × 100GE QSFP28 uplink ports in a compact 1U form factor, delivering a non-blocking switching capacity that supports the lossless, low-latency traffic demands of GPU cluster interconnects, distributed storage, and high-performance computing workloads. The switch is powered by Huawei's proprietary Unified Forwarding Engine (UFE) ASIC and runs VRP (Versatile Routing Platform) software, enabling advanced features such as RDMA over Converged Ethernet (RoCE v2), Enhanced Transmission Selection (ETS), and Priority Flow Control (PFC) for congestion-managed lossless Ethernet.

The CE6863-48S6CQ supports a comprehensive suite of data center networking protocols including VXLAN, BGP EVPN, ECMP, and BFD, enabling scalable overlay network automation for multi-tenant cloud environments and large-scale east-west traffic distribution. Its hardware-based telemetry capabilities, including iNOF (in-band Network OAM and Flow) and gRPC streaming telemetry, provide per-flow visibility at microsecond granularity, which is critical for detecting and mitigating congestion in AI training clusters where tail latency directly affects compute utilization. The switch integrates with Huawei's iMaster NCE network controller for intent-based automated provisioning, topology visualization, and closed-loop network assurance.

Designed for energy efficiency and operational simplicity, the CE6863-48S6CQ features front-to-rear and rear-to-front airflow options with hot-swappable power supplies and fan modules, supporting continuous operation in mission-critical environments. Its combination of high port density, lossless Ethernet capabilities, and deep-buffer architecture makes it a primary choice for enterprises and cloud operators building AI fabric leaf layers, converged storage-compute networks, and high-throughput HPC interconnects where bandwidth predictability and minimal jitter are non-negotiable requirements.

Ideal for

• AI and machine learning GPU cluster leaf interconnect, providing lossless RoCE v2 fabric with PFC and ECN for collective communication operations such as AllReduce in distributed training jobs
• Spine-leaf data center underlay fabric leaf node, supporting BGP EVPN with VXLAN overlay to deliver scalable multi-tenant network segmentation across large enterprise or cloud data center deployments
• High-performance NVMe-oF and all-flash storage network, leveraging lossless Ethernet and low-latency forwarding to meet the IOPS and bandwidth requirements of disaggregated storage architectures
• High-performance computing (HPC) cluster interconnect for financial modeling, scientific simulation, and real-time analytics workloads requiring predictable ultra-low latency and high bisection bandwidth
• Hyperconverged infrastructure (HCI) ToR switching for platforms such as VMware vSAN or Nutanix, consolidating compute and storage traffic on a single lossless 25GE fabric with hardware-enforced QoS
• Enterprise private cloud leaf layer within OpenStack or Kubernetes-based IaaS platforms, using automated BGP EVPN provisioning via iMaster NCE to accelerate workload onboarding and network lifecycle management
