I am a storage engineer. But I am interested in Dell products. There are some questions about me.

1. What is the bandwidth of the stack cable?

2. Why should I use two stack cables? Does the switch not work when only one is connected?
As far as I know, I know that stack cables must be used for synchronization, but I need an exact answer.

3. N4064F and N4032F. Are the two switches stacked?
I know that because the firmware is different, the stack does not work, but I need the correct answer.

4. I would like to know the official name of the stack cable. - model, cable name
ex) dell stack cable (model), cable 123 (cable name)

5. The cables using for extending the JBOD on the storage (full name: sff 8088 to sff 8088, 6G to 6G) and the switch stack connection cable look the same. Then, could we use the 8088 cable to connect the switch stack? Or if we use the 8088 cable to connect the switch stack, is there any problem with the switch stack?
