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...
