"please excuse the mess" _everything looks pristine, dust-free, brightly lit, neatly sorted into labeled boxes, and every cable is managed_
You tell this place is run by Germans, lol

Hey Roman, really enjoying the content you're posting on the EN channel. This video was super interesting, thanks for taking the time to work with Hetzner and letting us have a look at their operation. So cool!

[PedroM]

Hi Roman! I’m from Portugal and I have worked at Hetzner for 4 years in Falkenstein. Thanks for showing up the DC and all the found memories that I have from their and from the Hetzner team.

I've been a happy Hetzner customer for almost 10 years now. Have many many servers with them including some of the models shown in this video. I've had a few hard drives fail (as they always do) and Hetzner replaces them extremely quickly, I'm talking under 30 minutes.

Really excellent service and my only desire is for them to open more datacenters in more countries. North America (Canada, USA etc) would be wonderful as-well as Asia. I love their service and just want more regions for redundancy.

What an awesome facility. I love that they're using their heads for the cooling solutions instead of just spending a ton of money on, and wasting a lot of energy with, air conditioners -- even using the saw-tooth roof that some old metal foundries used to channel hot air up and outside via the angled ceiling to the high windows (I bet those high windows even face north or northeast, to avoid as much direct sunlight/heat as possible).

[ohkay]

That is so cool. Awesome of Hetzner to give you such wide ranging access as well. Thank you for this :)

[SeanHodgins]

I love all of the in house testing! What a cool company.

We have multiple virtual servers at Nurnberg but from the website Hetzner seemed like a small company, which it still is compared to AWS, but it's much bigger and profesional that I anticipated.

I'm really impressed.

15:30 Most times the DC from the batteries goes to the UPS. 3 phase UPS uses "double conversion" and what that means is that they take the AC from the mains and then convert it to DC (and that is where the batteries get connected) and then again the signal gets converted from DC to AC. This gives them a big benefit in terms of mains failure - 0 transfer time between mains and battery back-up, and the second benefit is the fact that this technology eliminates every "defect" in the mains - higher voltage, lower voltage, DC offset, swells... The DC bus on the latest gen of UPS devices is around 400-500VDC in order to achieve better efficiency (around 97% efficiency).
Some new data centers uses DC power to directly power the servers. This is done in order to gain efficiency by eliminating the DC to AC invertor in the UPS and the AC to DC conversion in the server PSU.

APC has some great White Papers on this topic as well as on cooling (as in warm countries it is impossible to use the outside air to cool the servers).

As satisfied customer of Hetzner it was really nice to see how they datacenters look like. I have been working as engineer/specialist for hosting company myself, so I have quite lot if information how datacenters are runned. I have been customer for Hetzner, for few years already, and I do have auctioned server and several cloud servers. Videos like this make those big hosting companies to feel more aproachable.

[Nordern]

Oh shit, one of those might be my server box!

[galileo_rs]

Very nice, been hosting my servers there for quite a few years now so it was nice to see how their setup looks. This also explains why my nvme drives are hitting 90c on regular basis.

[mrlithium]

Ahh reminds me of the good old days, before everything went corporate.
Makes me like them more seeing the normal and custom gear.

[alangarde]

Always fascinating to see data centers that work on scale. Great video.

[api]

Now I know i can sleep well since my servers are all there taken cared of like a baby. So great! Loved it.

[OldDogNewTrick]

Thanks for the most interesting tour. I am amazed by the size of this operation and the total amount of computing power contained here. I am from the old school of mainframe computers. First started working with computers back in 1965. One computer in an air conditioned room with a raised floor to circulate cold air. One CPU and 24K locations of memory in the typical system I first encountered.

[Gersberms]

This is great. It's interesting that Hetzner went with Asus to build their boards, I keep thinking maybe other brands aren't so bad but in the end I always stick with them. Though Supermicro is cool if you want to build your own server, I recommend it!

[novellguySA]

Thank you for this and taking the time to produce, VERY VERY interesting and well produced.

[kubak]

My very first server ever was in the Hetzner datacenter. Nice to see the company is still doing well

[christianrobertadzic]

Perfect video dude.
I love these organisation of a data centre.
I can remember the days I lived in Germany, how they care about thinks.
In Germany, nothing is impossible, they didn't care what other say, they just made it right and precise.

I'm missing those time really...

Thank you too Hetzner for such of trust you give to this guy.
