How to get MTBF of HP Servers. None of the manuals are mentioning anything about it. Also customer care guys doesn't know even what is MTBF means..!!!

 

You should make a formal request for a particular model.

But in the PC industry things change so fast that a model can be obsolete before there is significant experience with it And MTBF is so condition sensitive that any number that was quoted would likely not apply to your case unless it's a glass house environment with "typical" workload.

System MTBF will be limited by software in most cases.
Fans and drives will be the next highest offender.
