[nsp] Disaster Recovery

[Roberto Paoletti]

Hi guys, 
 
i'm studing for my site(banking) a solution for disaster recovery and
I'd like to have some questions:
 
-         Business Continuity------Disaster Recovery
 
To guarantee business continuity in a data center  you 'll let the core
in a only room or divide the core in a different rooms/floors?
Can someone help me for ideas,documents or link?
 
Thanks
