@mjg59 Okay, so when I was there in ops, we ran a bunch of private OpenStack clouds. There's MAAS (metal orchestration; should have been a component of OpenStack itself instead of NIH, but that's another gripe), and at the time we were almost exclusively an HP shop, but he wanted to dogfood MAAS with a variety of hardware.
The sane thing to do would be to set up contracts with manufacturers and give the hardware to a development and QA team. What he instead did was go on ebay, buy two random rackmount servers each from three manufacturers (can't remember the other manufacturers but the Dells survived as the internal meme mostly because they were basically broken), and had ops deploy them to a production OpenStack cluster. And ops was responsible when inevitably nothing worked right.
@ariadne @mjg59 Put it this way, for most of the 2010s, we had a moin page called WhichArmsSuckTheMost. It documented all the random assortment of slapdash ARM hardware which all the porting/building efforts ran on. I can't remember the exact words, but the intro was something like "all of them suck, but some less than others".
At one point the closest thing to sanity and stability we had were PandaBoards with custom enclosures, but they still sucked. But the page grew about a hundred panda gifs, and led to official documentation about how to stab the pandas when they misbehaved.
Sorry you're learning how the sausage was made.
@mjg59 Damnit I just told the same anecdote independently.
I thought the speaker was Jeff Waugh rather than a random tube denizen, though.
@mjg59 back in the day a bunch of Germans had to move a server to a new data center. To not lose it's 7 year uptime, they decided to do it online by using the subway. (Audio in German only)

@mjg59 I recall seeing a video of some crazy guys who hooked a server up to a UPS and a cell phone, unracked the whole mess onto on a trolley, then took it across the city by train so they could move it between two datacentres without any downtime.
And of course I can't find the video now.
