Cannot create partitions on 16TB disk

I have a brand new HP DL380e with 8 x 3 TB HDDs. During setup (2008 R2 std setup with Intelligent Provisioning) I use all of the disks to create one large RAID5 + spare disk of 16 TB.
I choose to install on a 100GB partition.
When setup is finished I have a C:\ of 100GB with the OS and a 2 TB partition I don't know where comes from, and about 14TB of unallocated space I can not do anything with. What must I do to be able to remove the 2 TB partition and format all of the unused space to one large partition?

As additional information the best way to setup partitions on an HP server is through the ACU utility that comes with the server.

1. Boot the server. During POST, the system recognizes devices.
2. When the system recognizes a Smart Array controller, press F5
The system launches the ACU GUI.

Once you are done with the configuration you can use windows to format the drive as GPT through Disk Management.

Common problem and leew has the answer (although the wrong terms) - "two RAID containers"...

Create two separate logical disks on your single array of physical disks, one small one to boot from and a large one that you can convert to GPT before putting any data on it. The ACU through AI/SmartStart is needed to do that since ORCA doesn't have all the options needed for anything but the simplest settings.
Actually on Dell Servers (at least a few years back - PERC 3/4 days) they were called Containers.
Yes, but this is a Smart Array controller, hence different terminology. Just making sure they find their way around the ACU.

OK guys

Thank you all. I will replace two of the large disks with smaller ones to install the OS. Which is what I would have done if I had been in control of this project from the start. This is how it goes when the sales dep. don't check with the tech guys prior to ordering HW. I just wanted to see if I had missed out on any solution. Thank you all.
You don't need to do that as Lee and I have explained, you can make a hardware partition in the array so that Windows sees it as two disks. Don't blame sales since it's a perfectly good configuration.

Yes, that is a possible solution. But in the end I would like my OS and my data on separate RAIDs. I believe that is a far better solution than putting all your disks on one RAID. Thank you.
