Using RAID and Mirror configurations under Virtual PC

Using RAID and Mirror configurations under Virtual PC

  • Comments 5


One obscure thing that you can do with Virtual PC is to configure it to support software RAID and Mirror implementations While this is rather pointless from a practical perspective (as you are not actually gaining any performance or redundancy) - it useful from an educational point of view for people who wish to familiarize themselves with these technologies - and the process of recovering from a disk failure.

As you can see in the screenshots below - I had configured a virtual machine with both a mirrored boot disk and a RAID-5 secondary volume.  I then removed the second virtual hard disk, replaced it with a new disk and recovered the data:

raid1 raid2 raid3 raid4 raid5

While this was interesting to do in a virtual machine - I was much happier to be doing it there than having to try this out on a physical computer with valuable data on it :-)

Cheers,

  • Please add 6 and 1 and type the answer here:

  • You mention that it would be pointless to do this in a VM, but you could also physically separate the VHD's for the redundant disk across different physical disks so that you would be getting actual redundancy.
    Obviously that can be abstracted from the VM and done for all VM's, but it is possible to use this a some form of drive redundancy on a single VM.
    Do you agree?
  • Just what I was thinkking Karan! So I tried it today and yes it works fine and I am getting real mirroring to two VHD files on different phycail disks :)

    I posted in the virtualserver newsgroup about this also if you want to reply there.
  • Hi Karan,

    Yes - this is possible and would give the desired results - but I would argue that configuring the physical disks in a RAID would make a lot more sense.

  • Hey I can't see your pictures. Could you fix so I can see how to run a raid drive in Virtual PC? Thanks.

  • tex - pictures fixed.

    Cheers,

    Ben
