it's my understanding that google mainly uses commodity hardware.
to get google's scale i would guess that they would have:
1. s/w to distribute data among many machines (note the google fs).
2. a system to bring up new machines with little human intervention
behond physically moving them.
3. a system for identifying boxes behaving badly. either a
physical indicator on the box, or a print out, or some sort of
pda based system. i'd lean towards the middle one. walk the
machine room once a day and rip out dead boxes, put in new boxes.
4. an agreement with a computer company (or two) to pick up dead
machines and drop of good ones - all within certain specs.
that leads to an efficient of labour and low equipment costs. assuming
i'm anywhere close to right in my guess, i'd kind of hope they work at
making sure those machines are energy efficient, and that they or their
suppliers do more than just chuck the "dead" machines.
regardless of the solution, everything i've read about google indicates
they don't use exotic hardware solutions.
