What's the largest size of a VHD for a MS Hyper-V VM

I have a hyper-v VM and added some storage to the host server (11TB).

I want to create a 7TB G drive and a 3TB H drive. Is this possible in hyper-v or is there a limit on the drive size?

Hello,

I have been using Hyper-V 2008 R2 and it's max allowable VHD size is 2 TB.  But that is the standalone free server, I am not sure if Wind2k8 ENT is different.

The way to find out is in the Hyper-V management tool, create a new VHD and it should indicate the max size in parenthesis next to it.

Still the same 2TB maximum size of a vhd, use a share on the server for increased size.

Resolved (with MS)

We assigned the space to the HOST machine and took then took the space offline.

Then in the VM we went and added a SCSI controller, with the drive set to offline you now had the option of assigning a PHYSICAL drive an option not available unless the allocated space has been set to offline on the host.

We then selected physical disk1 as the drive to add (all 12TB).

why you went this route, I have absolutely no clue. I never use physical disks for virtual machine storage.  IMHO virtual machines only contain the operating systems  and I use pooled storage for everything else.  You do realize that unless the host machine AND the virtual machine are online that this 12TB storage block is unavailable.  

I may be a bit strange but just using a shared drive and not using it exclusively for a virtual machine is what I'd do. This may work for you but personally I'd class it under not a best use of resources practice. C'est la vie
