Standard Mirror Configuration

The most common mirror configuration involves two servers with a mirror established between local

disks or partitions on each server, as shown below. Server1 is considered the primary server

containing the mirror source. Server2 is the backup server containing the mirror target.

N+1 Configuration

A commonly used variation of the standard mirror configuration above is a cluster in which two or

more servers replicate data to a common backup server. In this case, each mirror source must

replicate to a separate disk or partition on the backup server, as shown below.
