[PVE-User] RAID 10 with proxmox

Indeed, if it is the only option you have, SW RAID means Software Raid, 
so fake Raid. As Proxmox-ve use in fact a RHEL kernel, you can try the 
setup with RHEL option, but I am not sure it will work...

The best option is to invest in a good hardware Raid card (adaptatec, 
3Ware...).

The other option is to setup your Raid inside Linux, with Linux Raid 
Software, madm. See for example :
http://www.linuxplanet.com/linuxplanet/tutorials/6518/1

But it is not supported in Proxmox.  And I am not sure it will be 
possible, after Proxmox installs on the first disk, to configure a Raid 
10 with the three other...
