Raid 10 Bootable?

Thinking about building a Windows 2012 server with a raid 10.  I want to know is, can a server boot from a raid 10 or do I have to have a separate disk or a raid 1 to boot from?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is it the software-based RAID10, or do you have a hardware RAID controller.  If the latter, then no worries, the O/S doesn't even know the RAID level.    If the former ... no.

It is a hardware based raid.

Hardware controllers in most cases will do fine booting from a RAID 10.  HOWEVER, BE CAREFUL - The controller and the system must support UEFI and booting off GPT drives because MBR format disks can only support booting off a 2 TB "physical" disk.

With software there is a setup possible.
If you ensure the bootloader + kernel comes from a raid 1 partition on the disks...
then the remainder can be configured as a stripe set.
(This is a configuration used on many NAS systems, with say 8 disks, then there is a
part of the disk partitioned for firmware, 8 way raid 1, with 2 hot + 6 spare)
and the remainder of each disk in the wanted raid, 5,6,10..

If it is hardware RAID and as long as the presented LUN is <2TB then a UEFI BIOS is not required, and Windows will boot quite happily off whatever the RAID level is.

If the LUN is >2TB then a UEFI BIOS is required.

When using hardware RAID, as far as the BIOS/OS is concerned, the presented LUNs are locally connected SCSI disks.
