    Hi everyone. I'm planning to move local ESX4.0 VM and physical servers to Hyper-V. Need your kindly suggestion on the file server virtualization.

    It's a Win2003 physical server. Its boot partion is built on local RAID and data volumes are LUNs in EMC Clariion fiber storages. Since I have more than 1 TB data, I plan to create a Win2008 VM and "attach" the data LUNs to the VM to speed up the virtualization. But in 2008R2, pass-through disks must be added into failover cluster. And I remembered that I got data lost warnings when I add other LUN into CSV.

    I will be apprieciated for any suggestion on below questions.

    1. Can I "attach" NTFS partions created in a Win2003 Server to a Win2008 server? 

    2. Can I "attach" two LUNs in two fiber storages to one VM?

    3. Will I lose data when I create the pass-through disk and adding it into fail-over cluster or CSV?

    Hi.

    Short answers:

    1. Yes
    2. Yes
    3. No

    You don't have to add a pass-through disk to the CSV. Just open up the Settings of the VM via the Failover Cluster Manager and add the passthrough Disk to the VM.

    After you click ok, this disk will be added as a "normal" cluster resource, not a CSV. The drawback here is that when you do a live-Migration the Cluster has to Failover the disk to the other node which adds some extra offline seconds. But this should be no Problem with a fileserver. I have some customers with this configuration that works fine!

    The question is why do you want to add existings LUNs into CSV? THe only reason I can imagine is that you want to move disk where VMs reside to a Cluster and there into a csv.

    I had never Problems or data loss with this....

    Regards Olaf

    Hi olaf,

    Thanks for replying!

    My test on local network tells me the data transfer speed is 60MB/s to 80MB/s if I copy these data through the Gigabit network. As I said, we have about 1 TB data. So that will be 20 - 30 hours for the full migration. To decrease the downtime I think it's better to keep using these LUNs by adding them as pass-through disks. Thanks again for clarifying that I haven't to add passthrough disks into CSV.
