Windows - how to use something like "LVM" in Unix

Hi Gurus!

An academic question:

Scenario: two storage-systems, like EVA8100 or similar, in two different locations. Wan't to connect a Windows-server (actaully a VM-Ware guest, but that does not matter I suppose) to a data-LUN. Would like to mirror this LUN between the two EVA's "live".

In UNIX I would do this with LVM, which would make a uptodate mirror between the two EVA-LUN's and presenting them as one LUN for the OS.

But how would I do this in Windows? Use some kind of hardware for doing this? Using Windows Dynamic Disks, mirroring the two EVA-LUN's?

Ideas, of any kind, would be very welcome.

Thanks in advance.
Yours
Danny

This could be a solution:

Hope this helps!

The simplest way would be to set up the 2 disks as dynamic disks on the box, and mirror them using the OS's built in Disk Management.

It's no frills though. You set it, and forget it.


For a more robust solution, look for something with a Volume Manager. I think SVSP might be a bit to "big" for what you are looking for.

Yeah, we have looked into the SVSP.

If we choose the Dynamic Disk-route - if several guests on an ESX-hosts where doing this, would it make an severe performance-degradation?

Thanks everyone.

Kind regards

Re: Windows - how to use something like "LVM" in Unix

How are you presenting the disks to your vm's? datastore/virtual disk? rdm?


I don't think the performance impact will be "severe", but I hink it will be at least somewhat noticable.
