Hello.
You have 3 levels (servers, switches and storage) I understood it that way.
Most manufacturers have recommendation guides for installations with VMware and its equipment.
The usual is to have redundancy of fiber and network connections between all devices.
The firmware levels of all devices must be validated in both the manufacturer's and VMware matrices.
If your computers are IBM or Lenovo, I can help you with validations as a volunteer at no cost (Free)
