Looking to purchase a server need advice

I am really not great  looking at server details. I have the opportunity to purchase the server below

I need a rack mount server that I can split using VM Wear

I am aware the OS does not come with the server

I need to make 2 servers using VM Ware

The processor speed must be 2.5 GHZ or higher on each server

Both server must have a at least 1 TB of space. This does not include the hard drive space

I believe the server needs to be setup as RAID 5 with redundant power supply

Can someone explain this to me? Am I missing something?

Do I have to do something different when purchasing the MS Server license?

Both servers will be used for data mining

I belive it was explained to me that this server has (quanity 12) 600 gb hard drives and 2 Intel Xeon X5650 Processors
