This is OS level arrangements. not sure I understand what you are asking.

Whoever set it up, used Physical drives as dynamic and carved them up to setup the volumes and types...

Look in device manager whether these resources are comming from a SAN, or similar.....

You are using RAID mirror and RAID span on this configuration. Span means you can span one volume over several dynamic drives thus expanding the size of the volume like you did with E:
And yes, this is a software RAID and such representation of volumes and disks is absolutely typical for software RAID.

It's not called span, that's when you concatenate several disks one after the other, it's called "striped volume with parity".

Maybe they don't understand that some old servers didn't have hardware RAID controllers, must be pretty old with those disk sizes.

Yes, correct. Stripe was meant.
