This is more related to MS SQL than to VMware vCenter, basically from vCenter side you will need to create a DSN and point to the remote MS SQL server.
Here is the documentation that includes all database requirements that you should give to your DBA: Preparing vCenter Server Databases
BUT, if you're the DBA, take a look at these following links:
Create an ODBC 64bit connection on the vcentre server and point it towards the database on the sql server. At the end of the vcentre install just choose the ODBC connection you created previously.
