I agree that a pass-through disk is what you really want to be doing here – Hyper-V doesn't always have the fastest networking stack and using that stack to pass data between guest and host would not be the way I'd want to do it. You can easily set various LUNs on the RAID-5 set to be passthrough disks, or another solution would be to create a second VHD for your storage and just drop that on the RAIDset volume. (Less efficient than a direct pass-through disk, more efficient than using SMB/CIFS to pass data.)

I would put it on the virtual machine, it just feels better in my head that way. FYI, you can partition the RAID5 and just share the partitions to individual virtual machines. You don’t have to share it all to one machine. From: Oliver Marshall [mailto:[email protected]] Sent: Monday, November 22, 2010 10:43 AM To: NT System Admin Issues Subject: Hyper-V pass through disks or sharing disks Hi, We have a hyper-v host here with a mass of raid5 storage space locally. We want that accessible to one of the VM guests. There's two ways of doing this. Marking the raid5 partition as offline and then setting it up as a pass through disk and also just to share the raid5 disk on the host so that it's accessible over the network. Are there any pro's/con's to either? I like the idea of sharing it and having it accessible as a share as it means that the data is accessible by other VM guests and physicals as well. I'm assuming that throughput to both is going to be about the same. Any comments?
