[SASAG] Hardware Life Cycle Rationale

I don't have any sources, but here are a couple of points to
mention:
* Bathtub failure curves
* Unexpected cost of replacing hardware that failed after
warranty expired, vs budgeted cost of replacing hardware on a
schedule. How long will it take to get finance approval for a
new box vs having one cross-shipped under warranty? If it is one
of 100 loadbalanced webservers this isn't as big of a deal, but
if it is 1 of 2 failover database servers it is a much larger
exposure.
* Cost offset by eBay'ing old hardware (may not apply to your
situation)
