esxi 6 file server question

Hey Guys,

So I have a dell poweredge 1950 with two hard drive bays, 1 is a 160GB where I store all of my VM's and the other one is a 1TB drive that I want to share out to the rest of my network as a file server.

So my question is how do I install ubuntu server in esxi 6 and share out that 1TB datastore to the rest of my network?

Do I have to install the ubuntu server on that 1TB harddrive and then create shared folders?  Or can I install the VM on the 160GB HD and then share out the entire 1TB datastore?

Any help would be welcomed for a noob!

Thanks
