how to add a disk to a VM in order to be seen as a raw device?

I am running Hyper-V in Windows 8.1 Pro with Oracle Linux installed in the VM. I am running in the Linux VM an Oracle database (for testing purposes). I want to add a SSD which is seen as a raw device by the VM. Is this possible? How?

As far as I understand in order to assign devices to a VM you need Vt-d, which must be supported by the CPU (i7-4771), motherboard (Intel DQ87PG) and by the hypervisor. Is this correct? The CPU and the mobo both are supporting Vt-d last time I checked.

Thanks,
