Introduction
Welcome to Storage Mirroring Full-Server Failover! This manual is
for users who want to provide high availability for their entire server.
This chapter includes a Full-Server Failover overview, a list of
resources available to you while using Full-Server Failover, and a list
of conventions used throughout this manual.
Full-Server Failover
The Storage Mirroring Full-Server Failover feature provides high availability for an entire server,
including the system state, which is the server’s configured operating system and applications. Using
Full-Server Failover Manager, you identify your source, which is the server you want to protect, and
your target, which is the server that will stand-in for the source in the event the source fails. Once
the two servers are selected and their configurations validated, Full-Server Failover monitors the
source for a failure. When it fails, Full-Server Failover allows the target to stand-in for the source by
rebooting and applying the source, including its system state, on the target. After the reboot, the
target becomes the source, and the target no longer exists.
Full-Server Failover is installed with Storage Mirroring and is activated with your Storage Mirroring
activation code.
