comment What's the benefit of using “containers” in the datacenter as opposite to regular installation
I don't think that it's entirely certain that you actually get any economies of scale when it comes to cooling a datacenter. To continue with the economic terminology, cooling a large data floor is just as likely to run into diseconomies of scale due to cannibalization from "hot spots" ruining average temperatures. That's what these containers prevent, the diseconomies of scale associated with cooling large floors.

Also, in regards to (4) Management. You could replace "DHCP server" with "locally on every server" with no change in meaning.

I think it's worth mentioning that your reasons for not using DHCP aren't always as strong as they appear. 1) With regard to reliability, DHCP is one of the most reliable protocol/server implementations around. Problems with DHCP tend to be network problems, which tend to take servers offline anyway. 2) You can configure DHCP to be perfectly secure, this is a straw-man. 3) The DHCP configuration is great documentation. 4) Same, the configuration is the documentation.

comment DHCP for data center
Well, it depends on what you consider a burden. For many deployments, MAC addresses and IP addresses need to be documented anyway. A well crafted DHCP configuration file makes a great documentation for both. Every layer of the network stack is important to datacenter design, so "ignoring" MAC addresses really isn't an option anyway. Most admins I know prefer to reference the DHCP configuration file, rather than having to wade through router/switch configuration (or wait on a network admin to have time to respond).
