Where is this one?
KnC, i stole the picture here: http://www.bitcoinupdate.nl/home/cointerra-komt-met-zeer-matige-mining-contactenThe picture is from bobsag´s hosting facility, he therefore doesn´t own the majority of the shown miners.
It also looks like his thermal engineering isn´t optimised to the fullest extent, as there is a significant amount of unused space in those racks.

Hes already pulling a lot of density. Unless he can somehow duct out all of the hot air, im pretty sure hes capped to capacity due to not having a hot/cold isle containment.
It might be cheaper in the short term, but the increased footprint aswell as less efficient cooling and miners not profiting from optimal temperatures is more expensive after 6 months.
The tempurature on those units are all about 25-27c / 75C in/out. There is more than enough cooling, the reason the units were spread out was more because of PDU limitations than anything.
Is there some hot air containment or is the whole facility cooled as one?
It depicts a part of the newly added sha miners from GAWminers, the biggest scryptmining cloud service, and one of the bigger sha256 cloudmining services.
This datacenter is mainly to provide the sha option for their (previously only) scrypt mining hashlet primes.
(They operate multiple "datacenters" and are in the process of building a big one, afaik this isn´t a picture of the big datacenter).
They do host two of my S3s though, so who knows, maybe you can see it in this picture
(There seems to be at least one more row of S3s behind this one)

I obviously didn´t mean to say that the units aren´t sufficiently cooled (or the walls would start melting at such a high density).
I only stated that it wasn´t optimised to the fullest extent which I think is a fair comment to make.
This can be seen by the empty, not sealed spaces between units, effectively creating "holes" in the hot air containment system (if this exists behind the units, which cannot be seen).
If anyone wants to share their unit temperatures inside this facility, feel free to do so.
A good example of an optimised hosting facilty can be seen here:
When the racks are full (which they are to my knowledge) the lower static pressure caused by the exhaust fans in the hot aisle actually increases airflow through the units, outside air is cooled by evaporative coolers.
Jtoomim´s system seems to be a little more complicated but such a high density without any active AC is astonishing.
The footprint is smaller and the amount of hosted hardware is higher than in bobsag´s facility.

Nice, what will be the immersion fluid? Be sure to put something like copper sulfate in the glycol loops to prevent inferior organisms taking over.
Novec 7100. I have some test fluid on the way and hopefully I can get a test Neptune in the fluid on Monday or Tuesday and see how it does.
Are you using free air cooling or is it ACd?
With immersion you should get a better PUE, N7100 is single phase, right?
Is the stuff expensive?
How high is your power cost? Are you doing immersion because of high power cost or for fun?
It creates a coil like that, and inductive currents can blow both ends. I mean the miner controller + the rooter.
Wow, rly ? U think there is enough inductive current to blow something ? What u think how long cable needs to be ? And do u have some actual proof that did happen to somebody ?
Only asking coz i do internet networks setup, left cables like that if they are to long many times .
You get like 12V / 1A from induction when hanging a huge coil below a 10000V landline.
So yeah, the odds that a meteorite would crash into your home is probably higher than you blowing anything out because of induced electrical currents.

= 22680 boards (assuming 100% occupancy on all racks/rows as shown in close pics)
So if each board is like the batch 3 product boards then they should be apparently 750 GH/s each
So 22680 * 750 GH/s = 17010000 GH/s = 17010 TH/s = 17.0 PH/s
The current total network hashrate estimate is: 55.5 PH/s (https://bitcoinwisdom.com/bitcoin/difficulty)
So following the assumptions I've made for these calculations, this room would accommodate 30.6% of the total network's hashrate.
Please don't get shitty at KnC only based on my back of the napkin estimations.

Hate to point out an error but as batch 3 products typically consist of 4boards each, every board has ~187 maximum potential hashrate.
Thus total hashrate would be 22680 *187GH/s = 4252TH/s = 4,252PH/s
This would put them to a ~5.2MW power draw, assuming some minor improvements.
This model is in line with the fact that their datacenter is, i think, a 10MW facility.
On a different note though, producing these already designed ASICS including assembly etc. can´t have cost KnC more than 1$ per GH/s (it is propably a good amount lower).
So anyone converting their order into cloudhosting by KnC is just handing them atleast a 7k profit per order for outdated tech and hosting service.
KNC datacenter is mammoth. They got some strategy , first mine the shit out of miners and then send those miners to the customers for which they paid months in advance .
For what it´s worth they are planning on selling this as cloudhashing power, but first need to build their farm big enough to offer everyone of their Neptune customers compensation for any late delivery.
Without a doubt these petahashes are hugely profitable, but my guestimation is they are only at 50% deployment yet, as their facility supports 10MW power draw and they are only at a bit over 5MW right now XD
So yeah... atleast every Neptune customer is entitled to a refund if he spots cheaper hashpower anywhere...
Cloudhashing per se is actually quite a good idea, as it lowers the entry level for miners to become involved with mining and bitcoin.
This will eventually lower prices for cloudmining.
I guess what i´m trying to say is, that maybe in the end everyone can get a bit of their datacenter and feel good about it. At this point is it sadly just a symbol of KNC´s greed.

Right well then their website images are entirely
Those on the website right now are their new 20nm modules (aka Neptune, actually the same pics as the Jupiters in 2013) which are not yet in production (though tapeout was somewhere in march or late february i believe)
The ones in the datacenter are old 28nm, essentially the same as in the Jupiters, upgrade boards like on the website now.

Is that a laptop next to the knc?
Now very good time for any purchases. It is possible to buy any cryptocurrency and to earn with guarantee in the future.
Yeah? And who will give you the guarantee that every cryptocurrency will grow? Do not spread this information because people will start think that all cryptocurrencies are good and will be there forever.It's really simple. Use MyCrypto instead of Myetherwallet. It's made by the same team, It looks the same and it has more improvements so there is no reason why you wouldn't use it.
I haven't seen a single phishing attempt yet targeting Mycrypto, most likely because hackers are not really aware of it as of now as not many people use it. Either way, the domain name is shorter so It's unlikely that you'll fall it.
What is the main difference between mycrypto and myetherwallet? Both are online wallets, so how could you avoid phishing on some other online website?I haven't seen a single phishing attempt yet targeting Mycrypto, most likely because hackers are not really aware of it as of now as not many people use it. Either way, the domain name is shorter so It's unlikely that you'll fall it.
I think it is time to buy BTC and alts step by step.
We may not see this price again.
It depends on the market, if market will continue falling, then I would wait little bit more, there are experts who predicts 1000USD per 1 Bitcoin in the near future. But who knows where market goes.We may not see this price again.
Bounty hunters have become so useless that they now offer an ICO nothing. All their Facebook friends, Twitter followers, YouTube subscribers, whatever -- its all fake numbers and they always do the bare minimum to promote an ICO. Even ranks on this forum are faked. Merits are bought and sold, accounts can be farmed, purchased, for absolutely no purpose other than to spam this forum with useless information.
And what kind of traffic do they end up driving to an ICO website? Almost nothing. Most bounty campaigns literally have more participants than they will ever receive hits to their website, meaning the average traffic driven to a website by today's bounty hunter is less than 1 visit per month. Again, its because of all the fudged numbers. Everything is faked, nothing is real. There is no quality control whatsoever.
I really don't understand why anybody does social media bounty campaigns any more. Translations, graphic designers, website builders, app developers -- those are the real bounty hunters. Social media bounty hunters are just scum sucking parasites. They root through garbage trying to collect digital specs of nothing, leaving a trail of trash behind them.
Nobody wants to learn a thing about anything -- they just want "free money" as easily as possible, which usually ends up being worthless anyway. Would most of you just be sitting around doing nothing if you didn't consider this to be a means of "employment"? My guess is the answer is "yes." Feel free to correct me if I'm wrong.
I have same opinion. But you should also exclude from your list translations. Most of bounty translators do not care about the quality and they simply copy-paste into google translator and new translation is avaiable!And what kind of traffic do they end up driving to an ICO website?

Social media campaigns were useful when there were only few ICOs.
You are asking about Ethereum, about the distributed computing platform right? Not about the Ethereum´s price.
Ethereum developers are working hard, they will come with the new solution as soon as possible and this will make Ethereum great again!
