Product Overview
DBET-52 Series High-Performance Data Center Switches
The DBET-52 series delivers the high-density, ultra-low-latency switching required for modern data centers, cloud infrastructure, and HPC clusters. Featuring advanced deep buffer management and extensive scale, these switches are engineered for predictable performance under demanding workloads.
Key Features at a Glance
High-Speed Connectivity: Choose between 200G and 100G models to match your network's core and spine layer requirements.
Massive Scale: Supports large-scale network architectures with high-capacity MAC and VLAN tables.
Predictable Performance: Advanced traffic management with deep buffers (on 200G model) ensures lossless transport for storage and AI/ML traffic.
Comprehensive Automation: Fully programmable with industry-standard interfaces (OpenConfig, gNMI) for seamless integration into CI/CD pipelines.
Robust Security: Features like MACsec encryption, ACLs, and dynamic segmentation provide a zero-trust foundation.

Frequently Asked Questions
Unmatched Performance for AI/ML Clusters: The DBET-52/200G24K4M, with its 200G ports and 4 Mbits of deep buffer, is purpose-built for GPU-to-GPU communication. It minimizes packet loss and jitter, ensuring efficient and predictable training times for large language models (LLMs) and other AI workloads.
Guaranteed Investment Protection (Future-Proofing): Both models support flexible port breakout capabilities. The 200G ports can split into 50G, and the 100G ports into 25G or 10G, allowing you to scale bandwidth granularly and connect to legacy or newer servers without a hardware swap, maximizing your infrastructure's lifespan.
Automation-First Design for DevOps: The series provides a fully open NOS (Network Operating System) with native support for gNMI, OpenConfig YANG models, and Python scripting. This enables true infrastructure-as-code, allowing network teams to integrate switch provisioning and management directly into their application deployment pipelines.
Optimized for Hyper-Converged and Storage Networks: The deep packet buffers on the 200G model are critical for handling "elephant flows" and bursty traffic common in storage protocols (NVMe-oF, RoCE) and vMotion events. This prevents congestion and ensures consistent performance for your most sensitive data and applications.
Carrier-Grade Reliability and Operational Simplicity: Built with dual, hot-swappable power supplies and fans, the series ensures five-nines (99.999%) availability. A consistent CLI/API across the series and detailed telemetry streaming reduce operational complexity and mean-time-to-resolution (MTTR), making it ideal for always-on environments.
