Product Description
DBETE-5X/315G24K31A1V / DBETE-5X/315G24K31A1M
Rexroth original German imported proportional relief valve
Product Overview
The DBETE-5X 315G series delivers a new standard of predictable performance for the most demanding, latency-aware environments. Built on a robust 315G interface architecture, this series offers two purpose-built variants: one engineered for massive multi-tenant scale (31A1V) and another for deep network observability and analytics (31A1M). Both leverage the same ultra-low-latency alternative buffer (31A), providing the foundation for deterministic application performance.
Key Features
- 315G Optimized Performance: Utilizes a high-efficiency 315G interface for optimal signal integrity and reliable, long-reach connectivity in dense fabrics.
- Ultra-Low Latency Core: Both models feature the same 31 Mbit Alternative Buffer (31A) architecture, designed for the lowest possible cut-through switching latency.
- Specialized for Scale or Insight: Choose between extensive layer-2 segmentation (4,000 VLANs) for cloud networks or advanced telemetry (1MB cache) for performance monitoring.
- Massive MAC Scale: Supports 24,000 MAC addresses to handle large, dynamic data center environments.
- Consistent Management & Automation: Unified network operating system with full programmability (gNMI, OpenConfig) across both variants.

Frequently Asked Questions
1. Both models have the same 315G speed and 31A buffer. What is the main practical difference?
The core difference is their specialized hardware feature. The DBETE-5X/315G24K31A1V is built for massive logical scale, featuring support for 4,000 VLANs ("1V") to isolate thousands of customers, applications, or domains. The DBETE-5X/315G24K31A1M is built for deep network insight, featuring a 1 MB on-chip cache ("1M") dedicated to collecting granular, real-time telemetry data for performance analysis and troubleshooting.
2. Why is the 315G interface speed significant, and who is it for?
The 315G interface is optimized for superior signal integrity and power efficiency over optical cabling. It is particularly significant for:
- Large-Scale Fabric Builders: Operators building extensive leaf-spine fabrics where link reliability and reach are critical.
- High-Performance Computing: Environments that prioritize deterministic latency and low bit-error rates over absolute peak bandwidth.
- Future-Proofing: It provides a balanced, efficient upgrade path from existing 100G networks.
3. Should I choose the 1V (VLAN) model or the 1M (cache) model for my AI/ML cluster?
For an AI/ML cluster, the DBETE-5X/315G24K31A1M (1M cache) is typically the superior choice. The 1 MB telemetry cache enables In-band Network Telemetry (INT), allowing you to monitor micro-bursts, pinpoint congestion hotspots, and optimize collective communication library performance (e.g., NCCL), which is crucial for reducing AI training times. The 1V model's extensive VLAN scale is less critical in a dedicated, flat AI/ML fabric.
4. Is the 31A (Alternative Buffer) suitable for lossless RoCE (RDMA) traffic?
Yes, but with a key consideration. The 31A buffer is designed for ultra-low latency, not deep storage. It is excellent for RoCE traffic in environments with well-provisioned bandwidth and controlled congestion, such as tightly coupled HPC or financial trading systems. For large-scale, general-purpose AI/ML training or storage networks where massive incast traffic is common, a switch with a deeper, flexible (F) buffer might offer more congestion protection.
5. Can I mix both models (1V and 1M) in the same network fabric?
Absolutely. This is a key strength of the series. You can deploy the 31A1V model at the network edge or in multi-tenant pods where VLAN segmentation is required, and deploy the 31A1M model in the performance-critical core or adjacent to GPU clusters where visibility is paramount. They share the same operating system, management tools, and base latency profile, ensuring seamless operation and consistent policy enforcement across the entire fabric.
