availability and resiliency

Hi all, Does anyone know if a template exists for what it takes to provide 5 9's of availability, 4 9's etc.for Internet data centers? Specifically I'm looking for something that would say "if you want 5 9's of availability, here's what you need to do", and so on. Ideally, the template would define issues such as divergent fiber, redundant power, hot spares, etc. Thanks in advance, Irwin
