can we implementation RAID in vertual machine
 

Can we implement RAID in vertual machine for learning bases..
because some people say there can be chances of hard disk failure when we implement in actual hard disk.
so what would you say????
thank you

You can implement a software RAID by simply attaching several virtual hard drives to the VM.

Hardware RAID cannot be simulated, as I'm not aware of any hypervisor capable of emulating a RAID controller.

I think the basic question would be what do you mean, hardware raid or software? Software would be a trivial task and relate directly to production use and testing for the most part.


I haven't played with some of the advanced vm's on some of the very newest hardware. What I had heard was that some systems can allow pass though on pci and maybe some other buses so that a real hardware chip could be used.

To go the long way around this you could do some things like create an iscsi on a hardware raid and use it for the vm.

It might be possible to use zfs or btrfs or lvm in some vm setup.

why implement raid in the VM, and have the VM generate extra IO overhead, when you can place the virtual disk on an existing raid array?

I think they were testing a production server in a vm.
