Really nice!! so you do hosting with it?
Those were an interesting watch.
Its funny the difference between the high end and low end data centers with Hetzner's only having pc towers and the new OVH Video where the new servers don't even get a lid lol...
Yeah OVH looks pretty neat.. maybe I missed it but can't seem to see a power supply on each one of those board.. maybe they have something rigged up so they can achieve such density?
Yeah, I cant see a power supply either, the water cooling is pretty cool though, some pretty slim hoses so they have to be pumping that water pretty fast, I'm pretty sure they have it figured out but without a lid I would hate to be under one that sprung a leak.
Maybe they use mineral oil? I don't think it's conductive.
That's possible, I've seen people use mineral oil instead of coolant or water earlier. Not sure how that 'cools' the servers though, oil doesn't cool down faster than water.
yeah I suppose the thicker viscosity of oil might have an effect on the cooling efficiency compared to water but I would imagine that using plain water would be a fire hazard especially in the type of set up they have.. that would mean they have a lot of trust in their tech!
I wonder how old those OVH Video(s) are
Cisco Catalyst 9000 with SUP1A... 6408 line cards... yikes
agreed, with those small hoses they have to be running some type of voodoo liquid in there. Regular pc water cooling systems generally run either 1/2" or 3/8" tubing, 1/2" being ideal: more water = more efficient cooling. So yeah, probably oil or some super efficient liquid.

Have to say they were really ahead of their time for sure..
@javaj
yeah looking at those tiny hoses makes you wonder if it's really sufficient, but I suppose the scale that they are at it must be working for them.. I'm sure they have their secret recipe that we can't see from the videos, but i agree those hoses look awfully tiny to really do any good.
@Earl
The SUP1A was EOL on 09/2004
We still have 1 SUP2 based 6500 left in our private network, it's getting a upgrade to a 720 here shortly to bring it up to the standards of the rest of our equipment but it's ran line a champ for the last 8 years.
Maybe they decommissioned it right after they made that video? lol, but for the price they charge, I don't mind being on older hardware
their network has been pretty decent even thought it's only 100 Mbps port.. I just hate how they don't feel they have to be accountable for some of the things they do..
They upgraded to Cisco Nexus 7000, 5000 and for top of rack Nexus 2000 fexs. Oles has lot's of images in his twitter account.
Here's some more videos.
And here's another interesting video about Internet Archive, it has some server footage, very interesting choice of data center location haha :P
Pretty sure OVH uses water, not oil of any sort. They said so in one of the videos.
Speaking of home DCs, should not forget this guy http://arstechnica.com/information-technology/2013/05/fios-customer-discovers-the-limits-of-unlimited-data-77-tb-in-month/
Pretty sure it's not pure water but has some chemicals added. But yes, it's mostly water and definitely not oil.
Some overclockers claim to use oil to cool the motherboards, but they submerge the whole motherboard in oil. Apparently since it's not conductive it doesn't cause problems, as water would.
interesting
The opposite of that. They probably use distilled water (water that had all its minerals removed). Distilled water doesn't conduct electricity and improves hoses and pump life as it can't build mineral deposits that could block water flow.
Interesting to know

Ovh info on their water cooled builds

@tchen
Interesting... so by water cooling they mean "Hot Water Cooling".
Ok, those smaller tubes make more sense now.
Nice..
here is a few more pics of OVH water cooling.. found it on another forum, hope they don't mind.
so apparently they use regular water.. OVH mentions that "We do water cooling, and it is risky for your servers" one of the experiments when you pour water on a server..
Yup thats a pic of a server on fire..
a closer look at the heatsink..
The unused heatsink..
Maybe power supply?
That looks pretty cool I must say
It doesn't look 100% pretty, but if the solution works...
They use regular water??
They're going to have much more problems in the future than just damage from leaks, if this is the case.
I think it looks pretty good..
yeah you would think it's a real hazard.. but who knows, the DC have not burned down yet! lol
