if you want to make it an additional domain controller, fine
not recommended to put sql on the same box; keep it separate

If this 2012 server is already holding different roles and also acting as an application server for SQL, I personally would NOT be promoting this as a DC. Really there are no longer Backup domain controllers. Rather they are called Additional DC's. If you promote the server to a DC clients will start to authenticate to it and use it for DNS etc. This could compromise server performance for AD and other applications like SQL.

It is also not recommended to have addtional roles on A DC. The only roles that should be on a DC outside of SBS setup is AD/DNS/DHCP nothing else.

then, the recomendation is not, because the main function is sql, im searching for install certains featurs in order to take benefit of the new Hardware

Yeah i hear ya. Even if you do have the resources it is still not a good idea to mix these services up. However, what you could have done before setting it up as a SQL server is create a Hyper-V Host and then create individual VM's on this machine.

Doing this you are isolating the applicaiton to a specific set of resources virtually.

As stated above not recommended but it is what it is.

First of all, I'm going to assume the server is strong enough as its primary role will be a SQL server.

As this will be a BDC it's pretty straight forward.

After you join the server to the domain, install the Active Directory services and the DNS service.

After installing AD, promote it to a DC.   After the DNS service is installed, point each DC to each other as the primary DNS server for each other and put their own IP address in as the secondary.  Don't put 127.0.01., but the actual address.

That should be all you need to do.
