Gerald refers to the web scale datacentres, where the door is shut and
servers just fail, till this exceeds a certain threshold.
I would move this discussion on - the initial guarantee for HPC servers is
three years, with many customers in the UK Assking for a five year  year
support plan. After this the servers are disposed. of...
Have we faced up to the environmental impact of this?
It is often said that CPUs can be upgraded - I have only once seen an
upgrade in place in my career. By the time a couple of years have elapsed
you are better going for the next generation of servers.
I dont have a magic wand to wave to solve this problem, but it is something
we should be thinking about.
