well, its not 5-nines stuff, there's all kinda single points of 
failure.  you want 0.99999 kinda reliability, you need a fully redundant 
system with multipath, at every stage, like a fiberchannel SAN with dual 
HBA's on each system, dual switches, dual controllers on each storage 
array, etc, all components hotswappable, etc.  of course, this all comes 
at siginficant expense, both in complexity and cost.
