Asynchronous database mirroring is supported only by SQL Server 2005 Enterprise Edition Service Pack 1 (SP1) and later versions. When transaction safety is set to OFF, the database mirroring session operates asynchronously. Asynchronous operation supports only one operating mode—high-performance mode....
The configuration consists of only the two partners. When the partners are connected and the database is already synchronized, manual failover is supported. If the mirror server instance goes down, the principal server instance is unaffected and runs exposed (that is without mirroring the data)....
Updates made by clients to the principal database are applied on the other copy of the database, known as the mirror database. Mirroring involves applying the transaction log from every insertion, update, or deletion made on the principal database onto the mirror database....

RAID0+1 provides the performance advantage of striping, and the availability of mirroring. However, the cost is higher because you use twice as much disk space. Before determining the number of tablespaces and how to assign them to logical devices, determine the number of available logical device...
One way of creating a datafile backup on disk is to use disk mirroring. For example, the operating system can maintain three identical copies of each file in the database. In this configuration, you can split off a mirrored copy of the database to use as a backup. RMAN does not automat...
