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.
