Lastly, keep your configuration simple. Software RAID stinks. Fake RAID stinks. Only pure hardware RAID makes any sense at all, but a good hardware RAID solution is very expensive.
Sorry miss understanding.
It must be RAID 1.
Server is real and also RAID controller is real.
So once again...
Is it possible to create RAID 1 if we have one disk with data and one empty drive ? I mean, is it possible to configure RAID 1 without formating both drives ?
