Mirror iSCSI .VHD to local drive using Microsoft iSCSI Target: Similar to Kernsafe iStorage

Is it possible to mirror a Microsoft iSCSI .vhd...a feature that is similar to Kernsafe iStorage Server (http://www.kernsafe.com/product.aspx?id=5&&name=Features)?

Using Windows Server 2008 with iSCSI target 3.2, I have a d:\ drive (on one raid controller 1) that holds "mirror1.vhd" and an e:\ drive (on raid controller 2) that holds mirror2.vhd. I would like to mirror these vhd's and make them available to an initiating server.

The idea here is to protect the data in the mirrors in the event of a raid controller failure.

Is this type of setup even possible?

Thanks in advance

Thank you gtworek for this clarification...I was beating my head trying to find the answer on ths :-]

Andyalder...I'm looking at your solution. I have two Adaptec 5405 adapters, one running D:\ drive and the other running E:\ drive. I know that I could mirrior these drives using software based raid (Windows). Is it possible to do hardware raid on these adapters...somehow combining these adapters or do I need special adapters to support this configuration or is this option...not an option.

Thank your both for your help on this!

I can't think of any RAID controllers that do mirroring across two controllers (duplexing) but at least software RAID 1 doesn't have the CPU overhead of software RAID 5.
