Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I try to Install a Hyper-V 2012 Core on a HP Proliant ML110 G7 with a Raid 5 (4x3TB=~8TB for use). It seems, that this Server has no UEFI Support (can't figure it out). So I ended up with 350MB System-Partition and a 2TB Install-Partition. Diskpart shows 8TB, but only ~2TB are free. Is there anything I can do, to use the whole 8TB? Could it be, that the ML110 G7 doesn't Support GPT (I really didn't find any information, very dissappointing).

Any help would be appreciated

As a complete aside, you're absolute asking for data loss with RAID5. –  Dan Oct 23 '12 at 8:28
    
Don't know if you've been answered yet, but any RAID 5 array larger than 2TB is considered to be BAD practice, the rebuild time on a single disk failure becomes huge, and the opportunities for URE's (unrecoverable raid errors) grows exponentially. Best practice is to use OBR10 (One Big RAID 10) or if you can't afford the capacity loss (atleast on arrays larger than 4 discs) to implement a RAID6 install. –  user157879 Feb 6 '13 at 18:03

Make an OS VD of 100GB and then assign the remaining DiskGroup space to another VD which will be the remaining 7.9TB. If your system doesn't support booting from GPT partitions, this should work even without UEFI boot support. –  Martino Dino Feb 6 '13 at 18:09

People I still don't get what you all have against RAID5... It works even with 3TB drives, and yes the URE rate and rebuild times are higher than anything else, yet RAID6 is not the solution or any distributed parity RAID. The only acceptable solution is a good backup policy, and if you value your data, go with RAID1 or 10. And for anyone else, stop yelling at RAID5 like it's a guaranteed dataloss as it isn't especially with only 4HDD –  Martino Dino Feb 6 '13 at 18:15
