HP StorageWorks Storage Mirroring Full-Server Failover Evaluation Guide (T2558-96331, April 2009)

Introduction
Welcome to HP StorageWorks Storage Mirroring 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.
