Are you guys on commission to Dell, or something?
I fail to see why trusting your data to proprietary firmware - and
limiting your operating system choice in the process - is a better option
than a tried and tested open source solution. It may take a little longer
to figure out the optimum configuration, but at least you're not reliant
on a single vendor or unaudited code.
