Damn I just randomly thought of an idea to build a data center and wondered how much it would cost and boom…here are these guys with the walkthrough, from HVAC , to electricity. To backup generators , to plumbing & decor. Millions on millions I’m guessing lol
That's it -- I've just finished watching every single video that Custodian has published on RU-vid. I really appreciate the time and dedication it takes to document these topics and make them available for the benefit of others working in this field! Cable labeling has been briefly mentioned a few times but I believe it would be tremendously helpful to go into a bit more detail, such as what labeling nomenclature does CDC use? Are interface descriptions in routers or switches populated with circuit info? What is your process for provisioning new circuits - start to finish? How do you document and manage knowledge of all the connections in your facility? All industry best-practices but from the vantage point of what has worked well for Custodian. Just a few thoughts -- many thanks again for the brilliant work -- Cheers!
I can't help but notice that the gate next to the turnstile is too low for rolling whole racks through. My guess is that there is an alternative way to move a fully built rack into the corridor, but it wouldn't be weird to end up building a rack in the conference room and cart it over to its home when finished. Also, hope the fans have one way baffles to stop air from recirculating when a fan inevitably fails. Else that "two fans of redundancy" is not much of a thing. And at 2:10 we can see the turning wanes being installed very very far down. Usually one wants them inside of the laminar airflow one wants to direct, not after the curve one wanted them to direct. So that is a fail on the HVAC contractor's part. Also curious to ground sourced cooling, a bit too late to really install such now. But the ground has a lot of thermal mass and more or less keeps year round average temperature and would more or less remove the need for heat pumps for keeping cool during the warmest days. (though, just dumping heat into the ground each summer will increase the ground temperature over time, so in winter one has to suck out some of that heat, but the cooling units should have spare capacity during winter for that task.) A solution to add ground sourced cooling to the site would be drilling wells, but geological conditions will have to be considered.
Interested to know if you guys had todo the CDCTP course for your job? I work in a large building with one of the most powerful supercomputers in the UK and even though my job doesn't involve working on said SC, my company forced me todo the data centre course, which I passed but since it was mostly about designing a DC it wasn't really useful for my role. (I'm a Maintenance Engineer, look after Chillers, Generators, CRACs, AHUs, Heating Systems, Power etc etc, but don't really work in the Data Halls)
Its most likely due to meeting customer SLA's. They probably have customers in this new DC who state they need their racks operating at a certain temperature at all times, something that evap cooling wont be able to meet during hotter weather. In reality though, almost all servers can operate fine up to 35 deg, so cooling to keep temps at 22 deg for example is actually a waste of money and energy.
great video and excellant technical designe specially 2.5 meter steel doors. Just curios why not have overhead crane to load and unload cargo from truck then do it manually..?
