I'm very new in RAID Hardware. I want to know in case of a motherboard failure, whether I could transfer all drives in a different same model server with everything same, and configured in same RAID. Will it work, or what would happen in case of motherboard failure, how would I bring it back online?

The RAID setup information is stored on the RAID controller and on the disks themselves.
In the case of a motherboard failure (presuming the RAID controller is on the motherboard), your RAID config would not be lost as the disks would repopulate the new RAID controller blank config with the RAID config when the server is powered up after the motherboard replacement.
In the case of a different same model server, as long as the config was blank on the server, the same principle should apply and moving the disks to the new server (in the same slots) should work too.

Thank you for reply.
I tested it using everything same, different server completely same, and it worked.
Is there any risk for it to fail, losing configuration, and in that case data (assuming that we cannot do a backup after a failure).

If your spare server already has a RAID config on it and you move the disks over to the spare server, you may be asked during server POST which RAID config you want to use - the config on the RAID card or the config on the disks. In your instance you would always want to use the config on the disks.
