The Dell PowerSwitch Z9664F-ON is a part of the AI backend that is used for distributed training, fine-tuning, and inferencing, and can scale far beyond what has been discussed. In an example leaf-spine fabric, the figure below shows 96 switches connecting 256 XE9680s with 2048 GPUs.
This example Dell GenAI fabric shows:
- A GenAI fabric of 2,048 GPUs
- A Leaf-Spine architecture
- No link oversubscription between the workload clusters and fabric
- 96 Dell PowerSwitch Z9664F-ON switches
- 256 Dell XE9680s
