Failure of an indi#idual host

Advantages o' Virtual )isaster Recovery

Virtual machines are portableVirtual hardware can be automatically configured

)est and failo#er can be automated (minimizes human error$

)he need for idle hardware is reduced

osts are lowered* and the quality of ser#ice is raised

Site Recovery Manager Core Fene'its

B+pand disaster recovery protection6ow any worload in a VM can be protected with minimal incremental

effort and cost

Reduce ti(e to recovery

%s soon as disaster is declared* a single button ics off reco#erysequence for hundreds of VMs

Increase relia,ility o' recovery

.eplication of system state ensures a VM has all it needs to startup

Bardware independence eliminates failures due to different hardware

'asier testing based off of actual failo#er sequence allows more

frequent and more realistic tests
