availability and resiliency

[Irwin Lazar <ILazar () tbg com>]

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
