Based on our conversations with customers, we know that customers prefer InfiniBand or Ethernet. For this reason, the HPC Ready Architecture for AI and Data Analytics offers these options:
The following figure shows the Ethernet switch architecture:

The performance of both types of switches is comparable in most use cases. Customers must choose a networking switch that enables them to run multiple workloads at high bandwidth and low latency for best performance. The networking switch must have a fast connection to compute and storage resources for best performance.
