Topic: Pics of Huge Hosting Mine Under Construction, (Dec 2015 Update: We've moved) - page 13. (Read 54181 times)

It's good you have a lot of questions.

I'll let you know a bit about the economics of our wee venture.

Bitcoin could plummet to $40 tomorrow and miners here would still be making twice as much $ as their power cost.

Can you say ca ching?  



We have only built out 20% of the capacity our high voltage transformer provides. We bring power at 12700 volts direct to the complex.
If any investors want a piece of the action, my email is [email protected].

For the entire second half of that second video, what am I supposed to be seeing?  Nothing changed.

All right ASICSPACE, here's your chance to prove to me that this hairbrained scheme will work.  Answer my questions.

How much money did you spend renting this place, buying the miners, and building all this crap?

Who paid for it?

How long do you expect ROI to take?

With bitcoin difficulty already sky high and price low low, who among you thought this was a good idea?

I hope it works, but I see a financial failure in the making.  Like dmward's half-assed idea, but on a larger scale.

Funny you ask about HVAC.  We conducted a white smoke test yesterday, analyzing the airflow rates and patterns within the space and mechanical systems.  The testing involved a 20,000 CFM white smoke machine.

Here are some videos:

We have acheived this with only the HVAC for the first phase of our deployment. Will double the capacity of both supply air and exhaust air before the summer, as well as add several 60 ton compressor based AC units. We track hotspots based on a 3D grid of temp sensors we have in the mine, and will be adjusting ducting and containment to deal with any problems.

As you can see, the 20,000 CFM of white smoke clears in a matter of seconds in these videos, which is a visual verification of the fact that the room is changing air at the shelf level every 5-10 seconds currently.

Whats the total CFM capacity this facility has?  Also, what type of 'cooling' infrastructure do you have to keep all these miners cool? Evaporate cooling only? What do you expect your intake temperature to be with the maximum wet bulb during the year?  I have no doubt when its 30 degrees outside you have no problem keeping this place cool, but based on your design you don't have controlled hot air isles.

Honestly it looks like this place and all the equipment is going to cook when the temperature reaches 75 degrees / 80 degrees and they have 1mw of active miners running... Once you reach the tipping point, the temperature will rise indefinitely until units are shut off... 

Do you know exactly how many BTU's only 1 mw of equipment will put out? 3,412,142 BTU per hour, that takes, 285 refrigerator tons to cool....  With no redundancy...  I'm sorry I look at that ducting, and it appears no rhyme or reason was put into the facilities air cooling capacity layout... I've spent tons of time in data-centers before, and this thing looks like a disaster when your ambient temperature and wetbulb start to hit your summer months...  Its one thing if you have duct-ed / forced airflow and can provide 200cfm per KW (150cfm is standard per kw in normal environment) to dissipate / remove the heat out rapidly (200,000 cfm for 1 mw), but I can't figure out how you will accomplish this in your current configuration...

I mean I'd love to be proven wrong here, but what type of capabilities does your environmental system have to actually keep this equipment cool outside of the winter months?

Let me tell you, next gen systems like spoondoolies etc, hate it when the temperature climbs above 80f - 85f degrees

There is no such thing as "above ASIC".

I don't think miners would use the normal miners to mine specially there won't be a long term ROI, so we probably need something new in the mining technology.
has  there been something above ASIC yet ?

If by Gen4 you mean super efficient miners that are yet to come out, it's impossible to account for everything that may happen in the future. But that said as long as they still require electricity and cooling in mass, of course they can.

Are they capable of deploying Gen4 miners ?

I visited the ASICSPACE facility a few days ago and let me say it was clean! These people know what they are doing and did it right. They will be hosting quite a smorgasbord of miners for me while I get my own facility operational. They passed my own inspection with flying colors, very professional layout and very cold. HVAC is all there and very massive and impressive. Good job on this facility.

Cheaper to just buy most coins now...

We go as low as $75, which is about $0.10 per kwh.

The average rate in the US is about $.12/kwh, and that's not counting summer cooling costs, so yeah, it's about the same. But, the average home is very limited in power capacity, noise levels, etc. Sure, you can host a terahash or two, but not much more without a lot of effort.

So $80 per KWH is like $0.12/KwH

Don't most people in most places have cheaper electricity in their private home and at least cost the same?

I don't have the funds to prepay $90/kw/month is what I pay to run my miners from home so no point in hosting right now

Quite possibly, which is why I wouldn't prepay for a five-year contract. But if I buy a one-year contract, I don't really care what happens two years from now. Next year when the contract expires, I can re-evaluate whether I think another year will be profitable.


That I doubt. There's a high likelihood of a price spike in the next two years that will bring mining back into profitability, since the price can spike much faster than the difficulty can (bringing lots of miners online is much slower).

This mining farm is another case of too much, too late in the Bitcoin game.  

Everyone go back to page 1 and see the photos of the place under construction.

Now imagine the place mostly cleared out, empty, devoid of any ability to mine Bitcoin.  Random trash and shelving pieces litter the floor.

That is what this place will look like in less than two years.

And I also ask the question - why should the investors have any confidence that the people in charge of this place simply won't disappear with the mining hardware?  What is in place to force them to stay and mine?

I have predicted it here, check back later to see that I was right.  Bitcoin price may have some ups and downs, but over the next two years it will slowly but steadily do a lumpkin dive into unprofitability.

Depends on if you'd like to prepay your contract or not.

Prices range from:

$75-$90/kw/month

We can source PSUs for about $76 each for the SP20.

I can give you contact info of a few customers which have done that and send you some pics.

PM me your email and I'll shoot you a sample contract.

Thanks!

So how much would it cost in total to host the sp20 mini farm (15 sp20s all pulling around 1.2KW(1200 watts))

How about PSU's I assume those would have to be shipped as well ?  Sounds really risky to send all that hardware to a hosting company with no guarntees

Hey guys,

Just wanted to join in and say that I've currently got a bunch of SP20's mining in these guy's datacenter. 

As far as customer support - they can't be beat, they set everything up for me and there were a few issues and they took the time to make sure everything was running perfect, I was pretty much completely hands off.

Profitability - I was happy to see that I was still turning a small profit when bitcoin hit its low last week while several of my other mining investments went negative.  Right now it looks like I'll get my ROI in 5-8 months depending on BTC price which is better than most of the cloud services out there (a lot of them are creeping up on 12 months).

I've gone over their contract and it's legitimate and legally binding, they're not trying to hide their identities either which is a good sign.

That being said I think we all know that crypto-mining is incredibly risky business, so don't expect to get rich quick.  Just wanted to give these guys a shout out because I'm very pleased with the service so far

If your cooling fails you will find that the concrete might work against you for a few days afterwards. 

I design data centres for a living, or at least that is one of the things that my company does.

We've been called into DCs with completely failed cooling to provide advice and found that concrete walls can take up to 4 days to cool down from peak ambient temperature.  This puts huge load on your cooling when it comes back online again.  One medium sized concrete DC I remember had a total cooling failure for 24 hours (the customers didn't power down for whatever reason) and the walls stayed at 40 degrees celsius for over 48 hours.

Assume that thick concrete walls will act as storage heaters if something goes wrong and factor that into your cooling calculations.

As for high ceilings, I'm not sure what to think.  I've always been schooled to minimise the volume of the area to be cooled but maybe there is something to be said for a convective tower effect.  It seems a little non standard to me though as airflow is king.  Might you consider putting in a false ceiling?
