In a mirrored SQL Server configuration, which server hosts the principal copy of the database?

Explanation:
In a mirrored SQL Server setup, one server hosts the primary, or principal, copy of the database. This is the server actively handling client connections and write operations. The other server hosts the mirror copy, which is kept in sync by applying log records sent from the principal. The mirror is a standby that is not writable in normal operation, and only takes over as principal if a failover occurs (with or without a witness, depending on configuration). So the server that contains the primary copy is the Principal SQL Server.
