Add storage to VMware ESXi

Can you create a datastore with more than one physical hard drive at the same time or every datastore can contain only one hard drive?

How do you save the datastore if you neef turn off your host?

a comprehensive and state of the art short video. pls also explain
1. How to remove storage from server and side effects of removing so far.
2. How to add SAN with server physically and adding its storage in server.

can you make a video on how mapping between storage -> vm esx -> datastore -> vm (disk) and how to identify the same disk at each level

do you have a video explaining how to add a disk to a vm. I want this disk to be formatted by Linux (i think) as ext4. It will soley be storage for that linux box which is physical 2tb disk

I have an ubuntu server 20.04 liver server on VMWare ESXi 6.5.0 so now i want to add more storage to my ubuntu server how can I do without shutting down my server?
