I have a vmware esxi 5 running on a server with ssd and two hard drives. The server comes with software lsi megaraid and intel rapid storage raid. Neither of them work with esxi.

I need to somehow setup a fakeraid inside virtual machine to keep a copy data on each drive (raid0).

Is it possible to do so?

I must of been tired when posting this questions but I should clear something out. The questions is about setting up fakeraid for virtual machine or guest-os. –  jM2.me Mar 24 '12 at 16:12

ESXi is not supporting fake raid. You need to create 2 VMFS and add 2 disk each on one of the data stores and setup software RAID on the guest OS. You will have redundancy for VM, but not for ESX itself.

If you go this route, another option would be to expose the disks to a VM as raw block devices (instead of adding the extra VMFS layer) with vmkfstools --createrdmpassthru. –  Shane Madden Mar 17 '12 at 19:01
    
Sorry for late reply but this is what worked for me. Thank you Mircea and Shane –  jM2.me Oct 14 '12 at 16:44

You should use supported hardware. Fakeraid solutions aren't in the scope of VMWare ESXi blessed setup. You can make things work by acquiring a hardware RAID controller from the VMWare Hardware Compatibility List, though.
