Why Choose the S9827-128DH-W1?

🔹 Ultra-High Density, Zero Oversubscription

128 QSFP112 ports deliver full-line-rate 400GE forwarding. Flexible port splitting (256×200GE or 100GE) maximizes server access density without bottlenecks.

🔹 Intelligent Lossless Fabric

Full support for RoCE v2, PFC, ECN, AI ECN, and Agile Buffer technology ensures zero packet loss and ultra-low latency — essential for GPU/DPU clusters, AIGC inference, and distributed storage.

🔹 SDN-Ready & Fully Programmable

Programmable switch ASIC with Netconf, gRPC, and Telemetry support enables real-time monitoring, automated fault diagnosis, and dynamic configuration — built for modern DevOps and NetOps workflows.

🔹 Carrier-Grade Reliability

Front-to-rear airflow, redundant hot-swap power and fan modules, and multi-layer protection (over-voltage, over-current, over-temperature) guarantee 24/7 uptime in mission-critical environments.

🔹 Comprehensive Security & Management

SNMPv1/v2/v3, CLI, SSH 2.0, SSL, ACL, AAA, 802.1X authentication, and native integration with H3C iMC for centralized, simplified network operations.

Ideal For

• Spine nodes in Spine-Leaf data center architectures
• AIGC / AI / ML training and inference clusters
• Cloud computing platforms and distributed storage systems
• High-performance GPU/DPU server interconnects
• Core/aggregation layers for enterprises, carriers, and internet companies
