NVIDIA Switch Solutions: Frequently Asked Questions - Segmentation and High Availability from Access to Core

NVIDIA switches support multiple segmentation approaches to optimize AI data center performance and security:

• VLAN-based segmentation for logical isolation of AI training, inference, and storage traffic
• Network virtualization enabling multiple virtual networks on shared physical infrastructure
• Quality of Service (QoS) partitioning to prioritize AI workload traffic
• Security zone separation between user access, management, and data planes

NVIDIA's high performance networking architecture maintains consistent performance through:

• Non-blocking switch fabrics across all port densities
• Advanced traffic management with deep buffers for AI workload bursts
• Lossless Ethernet capabilities preventing congestion in RoCEv2 environments
• Line-rate performance on all ports simultaneously, regardless of segmentation

NVIDIA switches provide comprehensive high availability capabilities essential for AI data centers:

• Hardware redundancy with dual power supplies, fans, and management modules
• Hitless failover protocols ensuring continuous operation during component failures
• Multi-chassis link aggregation for active-active uplink configurations
• Graceful system upgrades without service disruption
• Network monitoring with real-time health diagnostics and predictive analytics

Maintaining low latency while implementing segmentation is achieved through:

• Cut-through switching architecture minimizing processing delays
• Hardware-accelerated segmentation reducing CPU overhead
• Optimized forwarding paths for intra-segment and cross-segment traffic
• Priority-based flow control preventing congestion-induced latency spikes
• Dedicated AI traffic classes with expedited forwarding

For optimal performance from access to core layers, we recommend:

• Implement hierarchical segmentation matching organizational and application boundaries
• Use consistent policies across access, aggregation, and core switches
• Deploy automated provisioning tools for segment management at scale
• Monitor segment-specific performance metrics for AI workloads
• Plan for segment growth and evolving security requirements

NVIDIA's high availability solutions for AI data centers include:

• Active-active fabric architectures eliminating single points of failure
