As someone who works in a nationwide bank, let me tell you why we
choose IBM and Sun hardware: support. If we want to get a server for a
project, we can't just go get the most cost-efficient thing out there
for the job. We have a short list of servers that can be picked from,
and that's it. A given server makes it onto that list if and only if it
can be supported by a vendor in a matter of hours for at least 3 years.
We don't always purchase that support, but bank policy says it has to
be an option.
We don't generally purchase monster machines. Sure, there are some
mainframes, but they are few and far between. Everything else doesn't
really have anything more than 32 procs.
