Full-Server Failover Option
The Storage Mirroring Full-Server Failover Option 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 Option
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 Option is installed with Storage Mirroring and is activated with your Storage Mirroring activation code.
