Actually, Adrian has a point.
Nano CPU's can be bonded for additioanl load.

Mercedes make a Deisel that turns off cylinders not in use.

It makes sense to devise a server that is capable of doing the same
thing.
Interesting - Bernard claims multiple cpu's are required for redundancy
and load, and Adrian claims that a server with multiple cards with CPU's
being turned on by demand is a more efficient model.

>From my CCI (Harris Scarfe) mini computer days (1985-86), I vote for
Adrians idea. Smaller CPU's load sharing as demand increases; and one
owould think, the individual CPU's can be selected to replace failed
cards so redundancy is built in.
That was pretty much the ICL DRS 300 SCSI (1990) backplane approach - it
worked - well. Small paralell independent processor units that could
load share tasks.

An interesting option  - methinks.
