I am compiling a list of the largest known Bitcoin clusters in the world.

** this list is now outdated **

I start with the following, but I am sure that's just a few of them. We should probably also include the cloud hashing companies.

There is the KNCminer data centre in Boden,  Sweden. KNC has said it will mainly be used to provide hosting services for KNC miners.

It is in an old helicopter hanger and located in Boden because of cheap power and easy cooling.
 
It is aiming for 10 Megawatts.  It has been running for some weeks.  

It may already be running at about 3 petahash and represent close to 8% of the entire Bitcoin mining network.

Everything should be set wednesday. Scrypt rig is moving.

Anyone know what gigavps is running? Id be shocked if he isn't on this list.

Damn you pay a lot of money for power.  I'm just starting to move units into our cage and it's only when you start paying for DC power and hosting tat you realize how important ghash/watt is because you end up paying through the roof for inefficient units.  Someone really has to design a truly power efficient asic soon.

I wonder how long it will take for the "MegaBigPower" cluster to get ROI :)

Eligius is down now so I forget the exact hashrate, but according to the top miners stats he is running over 100TH.

That's only 100-200kw isnt it?

A comment on the above mention of using traditional data centres to host Bitcoin miners.

Putting Bitcoin miners into traditional data centres is not going to be cost effective unless you can get some really unusually deal - for example use of a disaster recovery data centre subject to no disaster occurring.

A traditional data centre is always going to be expensive. It is set up to provide very stable and reliable power and air conditioning.  Bitcoin mining does not require this level of environment. 

The UPS and generators in a traditional data centre are not needed and are just a wasted cost. It does not greatly matter to Bitcoin mining if a power outage takes mining down for a couple of hours each 6 months.

Most of the air conditioning can also go. The tight temperature and humidity requirements of hard disks are not relevant to bitcoin mining.

All bitcoin mining needs is very cheap power and a rough and ready way to remove lots of heat. 

I would suggest the only large scale way to go is to find a secure warehouse area with lots of cheap power.  Its even better if it is a cold location allowing easy air cooling.  That way you can get away with simple air conditioning.   Alternatively large scale mining can use immersion cooling.

In summary the traditional data centre is not the way to go for large scale mining.

Yeah, ONLY 200kW.  ::) ::)

I am a bit puzzled why theres non of the really big farms on Iceland..

Power costs for iceland will be high, as its either geothermal or imported gas.

Hmm... Iceland is known to be cheap when it comes to power..?

I got quoted once for a full 1kw power, cooling and i think it was 4u for 75€ a month - including i think it was 1tb of data traffic..

is that expensive?

It looks like gigavps is running ~116TH.
http://eligius.st/~wizkid057/newstats/topcontributors.php

Do you really think 200kW is a lot? I currently have a 200 Amp breaker in my house, and use 100 Amps just for mining with 240V outlets, which puts my mining capacity at ~19kW (100 Amps * .8 * 240V = 19200 Watts).

I'm debating adding cooling and an additional 200 Amp breaker just for mining. That would increase my mining capacity to ~57kW (300 Amps * .8 * 240V = 57,600 Watts), and this is just in the basement of one residential house.

Granted, this setup will require a lot of expensive cooling in the Summer, and some of the extra power will need to go towards cooling, but I'm comparing those costs versus the cost of data center hosting. Data center hosting is expensive, and my electricity is relatively cheap at 12 cents per kilowatt hour. It's also nice to just be able to go down in the basement and deal with any issues should they arise.

After an electricity and cooling upgrade, I can realistically run ~50TH in my house using equipment that uses 1W/GH. I suspect miners will be available in Q3 of this year that will only use .5W/GH, thus increasing my max capacity to 100TH.

Being able to afford 50-100TH worth of mining equipment is another issue altogether, but it's not that difficult or expensive to upgrade most residential houses from 200 amp service to 400 amp service and use 240V outlets for mining.  :)

Gigavps showed 108 Ant Miners recently = 20TH

BioInfoBank 100TH-mine project this might be the same as MegaBigPower. They claim to have power costs of only 0.024 USD per kWh! :o
https://picostocks.com/businessplan/19.pdf

I suspect anyone who makes mining hardware probably also owns a farm... er... I mean customer hosting facility, obviously! ;)

200kW for the average miner and/or enthusiast? Absolutely.

200kW for a data center? Heck no.

We're running ~17kW, and we're pushing the limits on what we have available. I would love to be able to pump out 100kW or more.

Don't forget cloud hashing in Iceland:

Thanks for the infos, I 've updated the original post. Still all very early, but we are getting there.

Would be great to have more info on these two and the original AM farms. I am going to send a couple of PMs.

Where did you see that each AM farm is 500KW?

PETA mine

http://www.peta-mine.co/
Location: Brussels, Belgium

currently at 108TH

(30 Cointerra TerraMiner IV, 70 CoinCraft Desks)

165 CoinCraft Rigs along with 250 TH of custom board forthcoming
each datacentre unit support up to 500TH.

The HK facility was stated as 500kW several times. Also on the youtube video.
In Friedcat's early updates about the original farm he spoke about 0.5MW approval:
https://bitcointalk.org/index.php?topic=99497.msg1692732#msg1692732

No idea on the satellite clusters though. That's all  old stuff, so to speak.

Thanks, good find.

What's that in kW?

30 TerraMiner IV: 60kW
70 Coincraft Desks: ??? kW
165 CoinCraft Rigs: ??? kW
250 TH of custom boards: ??? kW

The power is the only thing that wont change. hashing power will change all the time.
 
Facilities are measured in power, not hashrate.

very true. unfortunately peta has not yet provided any information about power capacity
I know they work with solar power. a data-centre in brussels is certainly not the best choice, maybe siberia or kuwait or similar is better choice. The assumption is majority of units will be based on A1 chip and so there you can extrapolate the capacity from 500TH of A1 based on their power efficiency. Coincraft desk is ~400W afaik at 1TH, supposedly rigs come in at 3000W for 2.8TH

https://bitcointalk.org/index.php?topic=318010.msg4412552#msg4412552

on 9th Jan 45% of cex.io total hashrate was there in Ukraine

hoping you all can extrapolate the needed facts

Seems to be the 100TH IPO that founded MegaBigPower?

I believe MegaBigPower pushes 1000TH of which they claim 500TH is used to pay the shareholders at Picostocks 100TH.
(unfortunaly for the shareholders it's month after month "bad luck" so I guess the MegaBigPower-part 500TH got the luck)

Wasn't the MegaBigPower mining operation financed by bASIC customers that got screwed by this "Satoshi superstar" Thomas van Riper (http://www.satoshisuperstars.com/cablepair/) ?

That satoshiscumbag owes me over 50 btc. Sorry, I'm still pissed! >:(

Im not happy with my investment in 100TH too. I hadnt realized that i only fund the business for others. Then they had delays and i got out with a big loss only. I think the only one that earned big is the one that now has an asic and a miner design for free.

I've only seen the plan posted by gator-hex above (early 2013).


Is that the investment you are talking about or was there another one for 100TH?

What was the reason for the delay?


Unfortunately that seems to be a recurring theme. Icedrill basically made everyone rich, from data center to Cointerra, but the way I see it the investors will be in for a long wait if anything comes out of it ever. Friend of mine put a lot of coins (that he earned with real work) in them and now he's screwed.

Any more info on the CEX network and Peta Mine?

There must be a few more large clusters out there, if not people can probably stop complaining about the happening of decentralization with the current total network hashrate compared to the few we have above.

Might be wise to ask organofcorti do some analysis on pools that report user hashrates to see if consolidation is truly happening.

Im curious to the owners of these insane farms, is it part of a company, privately owned, etc.?

Yes, Tom (cablepair) was the head of the bASIC failure. IIRC, he was the one that ran off with everyone's BTC. I know Dave (BuzzDave) was associated with Tom, and was an employee at the time, but I don't remember him being malicious or stealing anyone's coins.

That said, Tom is basically a nobody now, and Dave is now managing the largest mining operation in the world. Does seem a little suspicious.

Not really. While Tom was very slow at providing refunds (which scared and pissed off a lot of people), he pretty much refunded everyone.

Could you remember where you got that offer from ? I think it is quite good.

Definitely not true, but too offtopic for this thread.

When I started out mining I had 0.2 % of the all the hashing.  That was 15 bitcoins a day at the time on a $30,000 investment and 6 kWatts electricity.  I thought I would never make that back.  Now I'm .004 % of the network on an additional $40,000 investment, 3.2 kWatts and I'm making 0.15 bitcoins a day.

If I was to purchase my original portion of the network I would need to buy 74 Antminers S2s for $266,000 and add 74 kWatts of electrical service to my basement, garage and outhouse.  And I would lose money on it.

Times change.  I stopped buying equipment months ago.  Holding bitcoins is way more profitable.

Why does saying that you're 0.004% of the network sound more impressive than saying you have 1.3TH/s?

What the hell kind of hardware are you running that gets 1.3TH/s on 13kW? Our 2TH/s of ants use 4kw, and those aren't anywhere close to the most power efficient units out there... 1.3TH of BFL Singles should be ~5.3kW... You running the first Avalons? Those 88GH/s units that pulled 1000W? Well that's why you're so angry. Upgrade your hardware, get some hashrate increases, save some power, and you'll be in a much better position!

Replyed to the pm :) - Lemme know how it goes

If you would be so kind as to PM the info to me as well I'd be most grateful  8)

I just found these today while surfing the web, though they might interest you...

Dunno the name of the farm but looks like Bitfury miners.

http://www.cryptx.com/peta-mine/

That's Dave (Megabigpower).

Peta mine says 100 TH/s and Cointerra 28nm, so that's just about 125kW at 1.6TH/s per 2kW (TerraMiner IV). If they were fully deployed.

It's been a turbulent year, maybe this thread needs an update or we need a new one.

I also posted this a few days ago in the Energy Consumption of the Bitcoin Network (https://bitcointalk.org/index.php?topic=520977.0) thread.

The Math: (extract from an internal report)

• First difficulty drop seen in 2 years occurred 2 Dec 2014
• Over the next 85 weeks (21 months) a total of 2.1 million Bitcoins will be mined
• USD $735 million at $350/BTC, $1 billion at $500/BTC, >$2 billion at $1000/BTC
• 280 MW estimated Bitcoin network size today (compared to Google's estimated 260 MW, Facebook 78 MW)
• Block reward halving ETA July 2016 (85 weeks, 5 days as of today)
• Bitcoin output from 25 BTC to 12.5 BTC per block (next halving estimated 2020)


Historical Bitcoin Network Data:

Nov/Dec 2014 (today):

Hashrate:                     290 PH/s    (+35%)
Total Megawatt:                 280 MW   (home mining almost gone)
Megawatt Industrial/Data Center:    270 MW   (+35% 0.85W/GH new capacity)

August 2014:

Hashrate:                     214 PH/s    (+375% or 94%/month)
Total Megawatt:                 214 MW
Megawatt Industrial/Data Center:    200 MW    (>1000-2000%)

April 2014:
Hashrate:                     57 PH/s
Total Megawatt:           250-500 MW    (mostly at home miners)
Megawatt Industrial/Data Center:    10-20 MW

I have gathered tons of pictures and data about mines during the past year, but unfortunately it's all scattered in different folders and places on my computer since we are extremely busy building our own stuff.
