Hyper-V 2012 R2 HOST hard drive limit

Is there a limit to the size of the HOST hard drive?

I recently loaded Hyper-V on a server with a 2500GB hard drive array.  I did not notice till it was too late (server already in production with Guests) that the install created a 2047 GB partition and left 466 GB 'unallocated'.

Is there a 2 TB limit on the HOST?
