I have cut out the company information header and other "private
information", its a document for the people who have to authorize the
switchover from RedHat to Gentoo. I'm new in this company and have found
a lot of bad configured RedHat machines and replaced them with Gentoo.
Now i must explain my choose.

gentoo($Hardware + $software + $Maintenaince + $Man + CustomerSatisfaction + Security) \
= \
red_hat($Hardware + $software + $Maintenaince + $Man + CustomerSatisfaction + Security)
Explained:
Generally boss are not interested in how fast a program run but if it does what is intended for, ie they are not interested to know if a webserver return a page in 150 ms or 15 ms, as they an the users can't see the difference.
For sure you spend more time to install a gentoo server than a rh one, but gentoo should be faster to maintain.
(rh_inst_time + rh_monthly_maintain_time) when it reach (gentoo_inst_time + gentoo_monthly_maintain_time) ?
When using suse I was used to recompile only the main servers running on that systems this time expensive,
- compile in a separated tree all the libraryes
- document every configure used
- compile the server again
- a lot of man time spent
in gentoo you have simply to backup your portage overlay, your etc, shorter documentation time, the time spent is more from the machin part than to the man one, man time is more expensive.
Can you buy new hardware every 3 years instead of every 2 ?
Security is hard to explain, unless they already had broblem with it ;) but it can a heavy point.
How much did you learned from gentoo without the need for a external course ? How easy (time) it was to learn? this can be a minor point but always a point.
If you tomorrow will disappear how will do they with your gentoo server?
Think with the head of who must pay for you and for the infrastructure.
Hope it helps
