What was in the "Statement of Work"? I learnt: if you don't specify
everything you need/want then some company will offer without
that/these features - even if it is a crucial one for the solution.

What does your "Statement of Work" say about this?

Contractors can be "first point of contact" for the customer. So you
always call them - they tell you when you have to call Dell (or call
Dell for you if it is covered by the contract).

Right! Go for the specialists. There are some "hardware independent"
companys. They use whatever Hardware you like. As a customer (of a
certain size) you can even make the big ones work with a small
specialised company. The big guys just care about the number of
servers they sell... whatever makes that happen is okay...
