 I have Rocket RAID SATA RAID Controller with 4 x 1TB SATA HDs and created RAID 5 with no hot spare, so I have total 3TB effective storage space.
 I was trying to use all 3TB as one partition (for SBS2011 OS and data), but could not because it  created two partitions like below:

Disk1 Unallocated Space 2,048 GB
Disk1 Unallocated Space 746 GB

So I googled on 2TB Limitation with Windows 2008 and learned that you can't create BOOT partition more than 2TB, but also learned that I can create a data partition > 2TB.

I thought, then, I can create 200GB for OS partition and use the remaining space (2.8TB) as data partition. So when I saw 3TB partition showed up on Disk setup window, I entered 200GB. This time I get the following:

Disk1 Partition 1: System Reserved 100MB
Disk 1 Partition 2 192GB Primary
Disk1 Unallocated Space 1,852GB
Disk1 Unallocated Space 746GB

If I proceed to install SBS2011 on 200GB partition, will I be able to combine two separate partitions (1,852GB & 746GB)  into one (2.8TB) using COMPMGMT.MSC?
