2TB storage Limit Windows 2012 R2 on Intel Raid Card
We just go an Intel Server with 8 Drives and a PCI raid card with 1GB memory on the raid card. I did a Raid 6 with a total 8 drives ( 4TB each) . I installed Windows on the raid 6 volume that I created using the RAID bios. When the install finished and I logged in . I see a 2 TB partition which windows is on and then I see a 20TB unallocated space. Please see the attached image. What do I need to do to make the space usable. I was hoping to have two partitions on this volume since I was going to install Hyper-v and have two vm running and one being a file server with 12 TB of files on it. Someone suggested that this happened because I marked the volum as MBR when creating the RAID volum in the raid bois. ( yes, I did that) . When I go back in the bios , there is nothing there to remove that or change anything . I have attached some pictures. It seems like I could just extend the 2TB drive to the empty space, but I am not sure.

Graycase and Rindi,
I have an intel Rs25AB080 Raid card. I think by setting UEFI in the bios , you are talking about the RAID card bios and not the server's bios? Correct? , If so, in the RAID bios ( raid utility ctrl+ G during boot) , I do not see a UEFI option or can't find it.
Cliff, I appreciate your help in this post and the other post about hyper-v from earlier today, but going forward, please do not respond to my questions if your response is going to be " You need to know more, Understand x,y,x, and give more info" . Thank you,

So we (not just me, but all experts, are supposed to psychically know if your RAID controller supports 512e or native 4k disks? Or if your computer has UEFI support? Because both of those factors *FUNDAMENTALLY* change how you fix your problem. But hey, I guess you want free easy help with no effort while attacking those providing assistance. Good luck with that!

Good News. The Intel server had option that came to my aid . If you hit f6 during post, you get the boot options and one of those options is UEFI boot. When you do that , it will install the OS on a GPT partition. Or you can do Shift + f10 and use command line during install and convert the disk to GPT. Now I have a disk with 22TB.
Now I plan to Install hyper-v and setup a VM that will be the file server that will hold around 14TB of data and growing.
What would be the best way to do do this considering backup and snapshots? Should I leave this 22TB as it is or should I create two partitions.
Also, should I create a VM and then once the VM is created create separate virtual disk to hold the DATA for the file server VM. So, that I would have a C; drive(os) and D: (files) drive within the file server vm?
Thank you,

1 partition for the o/s and 1 more or many more for data (which includes the virtual machines)
With a gpt disk you can create unlimited primary partitions (not limited to 4)

David,
Within the fileserver VM which will hold 14TB data, should I have a C: drive ( os) and create another virtual disk for D: for the data? or should the vm data and the files be on the same drive?I wonder if there is a difference. ? Thank you,

Cliff's post was exactly what I would have posted, the link he gave is about "drives" as Windows sees them, i.e. virtual/logical drives as presented by the RAID controller and how to use GPT disks with UEFI.
Not until we knew it was a Rs25AB080 we did not know that it does allow multiple virtual disks on a single drive group. You can't expect him to guess it's a re-badged LSI controller without telling him what card it was.

David's solution was the one that allowed me to install the OS. Thank you all for your inputs.
