Al Switches

Dell offers high-density Ethernet up to 800 GbE (e.g., PowerSwitch Z9864F-ON with 64x 800 GbE) and 400 GbE options (e.g., Z9664F-ON with 64x 400 GbE). For InfiniBand, NVIDIA Quantum-X800 delivers 800 Gb/s per port with up to 144 ports per chassis, while Quantum‑2 provides 400 Gb/s. This gives you the flexibility to scale training and inference fabrics as your GPU footprint grows.

Yes. Dell AI Ethernet switches support RoCEv2 and advanced congestion control features designed for consistent, low-latency performance across GPU clusters. Enhanced hashing and optimized throughput help maintain stable job completion times under load.

The PowerSwitch Z9864F-ON delivers sub-microsecond latency (<700 ns), with nonblocking throughput across 64x 800 GbE ports. This performance helps minimize step times in distributed training and reduces fabric-induced stalls. It’s designed to support massive data movement typical of GenAI workloads.

Yes. Many environments use Ethernet for the broader data center and storage access, and InfiniBand for dedicated training clusters. Dell supports both approaches, and you can interoperate via gateways or data pipeline design while maintaining separate, optimized fabrics.

Start with nonblocking leaf–spine tiers sized to your GPU node counts and east–west traffic. Use 400/800 GbE on leafs and spines with balanced uplinks, and follow validated designs for hashing, buffer tuning, and RoCEv2 settings. Dell publishes reference architectures to accelerate and de-risk deployments.

800 GbE platforms like Z9864F-ON use OSFP112 ports, while 400 GbE systems like Z9664F-ON use QSFP56-DD. Your choice of DACs, AOCs, or optics will depend on distance and power budgets, and Dell provides qualified transceivers and cables for each platform.

Yes. Options include NVIDIA Spectrum SN2201 (48x 1G BASE‑T with QSFP28 uplinks) and Dell PowerSwitch S3248T-ON (48x 1G with higher-speed uplinks). Dedicated OOB networks improve reliability, upgrade safety, and troubleshooting for production fabrics.

Dell AI switches are validated with PowerEdge AI servers and PowerScale AI storage to maintain high throughput and predictable latency end-to-end. You can use published reference designs to size links, choose topology, and align storage bandwidth to GPU demand. This supports faster time-to-value and simpler scaling.

Yes. Dell Design Services for AI Networking tailors the fabric to your models, GPU counts, and growth plan, and ProDeploy accelerates rollout with best practices. ProSupport Infrastructure Suite delivers 24/7 assistance to keep your AI network performing at its best.

Yes. PowerSwitch Z9864F-ON earned TMC’s 2025 Unified Communications Product of the Year, with Z9664F‑ON and Z9432F‑ON also recognized in prior years. Independent industry accolades reflect performance and innovation for high-capacity data center networking.
