Creating biggest partition Using 4TB
Hi,
I have HP Proliant ML 110 G6 (test server) with two 4TB hard drives on a LSI MegaRAID controller. I created RAID 0 for each 4TB in RAID BIOS. This server does not have UEFI boot option. I installed Windows Server 2016 on 150GB partition. After OS install was completed, I ran diskmgnt. It asked me if I wanted GPT or MBR on "disk1" and I selected GPT and I see 3725GB as one drive (F:) in Disk1. But In Disk0 where I created 150GB OS partition, it shows two unallocated partitions (1900GB & 1677GB). How can I combine these two partitions into one?
Thanks.

You can't combine since MBR maximum size is 2TB
You not going to be able create any partition on MBR disk bigger than 2TB
All you can do is delete both partition and release to get Free disk space but you not going to be able to use it.

Yes because Like I said, maximum size for MBR is 2TB and you've already used this space for System Reserve+C drive+D drive. No more free space in MBR left

I should be able to get two 2TB partitions in MBR, right?
Should I go back and reinstall Windows Server 2016 and select entire 2TB for OS partition (at least to use all 2TB space)?

Call your hardware manufacture support and ask them if they have any new BIOS with UEFI GPT boot option

"consider adding a small drive (250G)" --> That is a good idea. Let me add that to the RAID.
"An option would be to split your Array into 2 separate virtual volumes, provided your controller supports that" --> I created 200GB partition out of 4TB virtual drive in RAID BIOS and when I installed OS on that 200GB, it does not show the rest of the space(3800GB) in diskmgmt. In RAID BIOS, I could not find the option to create 2nd volume for the rest of the space either.

I'm not talking about partitions. You need to split the array into two separate volumes. Not all controllers support this though. and sometimes they need additional options which you have to buy before they support this. The volumes must appear as separate disks to the OS, and not as one large disk with partitions.

@Tom "Call your hardware manufacture support and ask them if they have any new BIOS" --> They have a new BIOS, but requires active support contract in order to download the file. This server is very old and I don't have a support contract from HP.

Adding 1TB as OS drive did let me see two 4TB HDs as full 4TB drives in Windows.
Thanks for your help!
