Actually I HAVE done the analysis (in APL yet!) and
there definitely IS a
place for board swapping. Especially when you consider the down time of the
system and the cost of extra systems when you HAVE to have a system in
operation (specificly in Air Defense!)
At AOL, downtime obviously did not harm too many people as a failure in a
defense system, but sales took a beating. I forget the numbers, but for
the router interfaces, hard down time was SO damaging to sales that in
less than a minute, it would be cheaper just to buy a new interface ($18K
Cisco cards like loaded VIPs).
