Why would you call colocation "building your own data center"? You could call it "colocation" or "renting space in a data center". What are you building? You're racking. Can you say what you mean?
Reminds me of the old Rackspace days! Boy we had some war stories:
- Some EMC guys came to install a storage device for us to test... and tripped over each other and knocked out an entire Rack of servers like a comedy skit. (They uh... didn't win the contract.)
- Some poor guy driving a truck had a heart attack and the crash took our DFW datecenter offline. (There were ballards to prevent this sort of scenario, but the cement hadn't been poured in them yet.)
- At one point we temporarily laser-beamed bandwidth across the street to another building
- There was one day we knocked out windows and purchased box fans because servers were literally catching on fire.
Data center science has... well improved since the earlier days. We worked with Facebook on the OpenCompute Project that had some very forward looking infra concepts at the time.
This is a pretty decent write up. One thing that comes to mind is why would you write your own internal tooling for managing a rack when Netbox exists? Netbox is fantastic and I wish I had this back in the mid 2000s when I was managing 50+ racks.
My first colo box came courtesy of a friend of a friend that worked for one of the companies that did that (leaving out names to protect the innocent). It was a true frankenputer built out of whatever spare parts he had laying around. He let me come visit it, and it was an art project as much as a webserver. The mainboard was hung on the wall with some zip ties, the PSU was on the desk top, the hard drive was suspended as well. Eventually, the system was upgraded to newer hardware, put in an actual case, and then racked with an upgraded 100base-t connection. We were screaming in 1999.
It would be nice to have a lot more detail. The WTF sections are the best part. Sounds like your gear needs "this side towards enemy" sign and/or the right affordances so it only goes in one way.
Did you standardize on layout at the rack level? What poke-yoke processes did you put into place to prevent mistakes?
What does your metal->boot stack look like?
Having worked for two different cloud providers and built my own internal clouds with PXE booted hosts, I too find this stuff fascinating.
Also take utmost advantage of a new DC when you are booting it to try out all the failure scenarios you can think of and the ones you can't through randomized fault injection.
