ServeTheHome.com takes an in-depth look at how to configure Microsoft’s Hyper-V to use raw disks and RAID volumes:
After the recent article on passing controllers through to ESXi virtual machines, I did get some questions around pass-through in Hyper-V. First off, it works a bit differently in Hyper-V, but you can still expose raw disks and RAID volumes to Hyper-V virtual machines, and this does not require Intel VT-d. This is an important feature of Hyper-V because it allows for the virtual machines to get raw disk access which is important when you have a storage operating system controlling the drives.
