Default How can I create raid 1 - Centos 5.7 64 minimal installation

Hello,

I have a server working on centos 5.7-64 minimal installation. I have
3 separate physical drives:

120 gb ssd, 2x 3tb disks for storage.

My linux installation is on ssd disk, and I want to make raid 1 for
these two 3tb disks and store data, like under /mnt/data.

Can you please tell me the path how this is possible?
Thanks for your help!

Best regards,

Here are some output of commands I ran for more data:
