Storage System 1 then acknowledges the write to the production
host.
Database Server 2, the other host, has no direct access to the mirrored
data. (The standby site does not need a server at all.) This server runs
applications that access other data stored on Storage System 2. If a
failure occurs in either the production host or Storage System 1, an
administrator can use the management station to promote the image
on Storage System 2 to the primary image. Then the appropriate
applications can start on any connected server (here,
Database Server 2) with full access to the data. The mirror will be
accessible in minutes, although the time needed for applications to
recover will vary.
