Product Overview
Huawei CloudEngine CE9855U‑32DQ is a 1U fixed‑port FCoE‑enabled spine/aggregation switch of CloudEngine 9800 series, built for hyperscale AI data‑center fabrics, high‑performance computing, and converged Ethernet‑FCoE storage environments. It provides32×400GE QSFP‑DD high‑speed service ports plus 2×10GE SFP+ extension ports, supporting multi‑rate auto‑negotiation and flexible port breakout. It delivers 25.6 Tbps non‑blocking switching capacity and 8000 Mpps line‑rate L2/L3 forwarding performance with large‑capacity shared packet buffer (130 MB). Besides rich data‑center Ethernet features, it natively supports FCoE for converged SAN‑LAN deployment. It supports iStack stacking, M‑LAG multi‑chassis link‑aggregation, hardware‑accelerated BGP‑EVPN VXLAN, RoCE‑v2 lossless Ethernet, AI‑ECN intelligent congestion tuning, MACsec encryption and comprehensive intelligent telemetry O&M capabilities. It can be deployed as high‑speed spine node in spine‑leaf architecture or high‑end aggregation switch for converged storage‑compute DC networks.
