Garage / Residential Data Center Mining Cave Planning - Garage Grotto Part 1 :D

[Sequoia93]

Your panel appears to have plenty of room in it. Those blank gray spaces without switches can handle additional circuits, so you would not need to add another entire panel. The electricians will tell you exactly what they can put in, but I see room for at least 100amps if not more. I think you could fit 4 240v 50A circuits if you move one smaller circuit to the opposite side of the box. Then they can install however many outlets you need. You could do something like 4 50A ciruits, each with its own outlet, and plug a 50A PDU into each outlet. Or twice the outlets/PDUs with PDUs rated at 30A. But again, talk it out with the electricians, I am not qualified for such work so don't follow my advice without asking a real professional!

I also use EVGA PSUs which you can just plug into a 240v PDU. Some PSUs have 120/240v switches on the back (maybe only older models?). But your PSU should say on it somewhere something like "100v - 240v 50hz - 60hz". If it simply says "100v - 120v" you are out of luck. With that many rigs I would highly recommend getting some server PSUs to supply the bulk of the power anyways. Finksy sells entire packages that will make your life way easier. If he is out, pm me for additional sources.

Phil's diagram for airflow would definitely be more efficient than what I suggested. Here is a diagram of my suggestion: http://imgur.com/a/AQW9x

Again, its not ideal in terms of airflow, but it may be more feasible than putting a hole in the back of the garage, and sucking air from the house. Not to mention it will be LOUD with the door to the inside of the house open. Also note that you have to have enough louvers to match the exaust fan, too few and it will be extra loud and wear on the fan motor.

I do not know how much electricity your nvidia rigs need, but assuming you have everything running off 240v circuits and the full 200amps, then you can pull up to 240*200*0.8 = 38,400watts... so divide that by the peak power consumption of one of your rigs measured with a proper wall meter. While that could easily be 30+ rigs, you may run out of space/cooling capacity before electric.

I garage mine  I open a back door put in a box fan. in the summer not the winter

I leave the interior door open  almost every day of the year.


In the summer with ac running  3 kwatts  is my max

In the winter when it is 30 f  6 kwatts  is my max.


mind you I can feed  48 amps at 240   which is 11.5 kwatts    but house gets really freaking hot and wife gets very angry.

At the moment

 I have:

 8  1080 ti's
 1  1080
 2  1070
 1  1060

5 rx 480's

8500h of zec pull 3kwatts.

I will need to drop to

1.5 kwatts for the summer.

Quote one

10 gfci outlets 220v
100 amp sub panel
All wiring etc
Unsure on cfm exhaust fan and ductwork running out of back of garage his idea coincided with Phillips idea
Coax line

$3000

Quote two

Whole house surge protector with 75k warranty ($400)
30 220v outlets
Coax line
Same exhaust fan idea
Intake fan?

Quote still being figured

Should I be running 240v over 220v? Can someone elaborate please

What outlet setup do I need this part I do not understand,

I'll be throwing the rigs on racks, how can I run power to all of them and maximize my circuits

Can someone suggest how to accommodate all of these plugs effectively?

This is more minor but running the Ethernet cables - best clean option?

[Sequoia93]

As for 240 vs 220 I am not sure, is that european vs american standard?

Either way they are more or less the same, a PSU will be rated like "100v - 240v" and can be plugged into anything in that range.
Although I'll say again, DISCLAIMER, I am no electrician, please verify with a professional.

As for power, you'll want to pick up some 240v PDUs. They are very reasonably priced when bought used.

Ehternet cables can be tied along legs of the rack, and all plugged in to an ethernet switch such as this: https://www.amazon.com/NETGEAR-ProSAFE-Ethernet-Rackmount-JFS524-200NAS/dp/B00DCUKCVW/ref=sr_1_2?s=pc&ie=UTF8&qid=1494430119&sr=1-2&keywords=ethernet+switch&refinements=p_n_feature_keywords_two_browse-bin%3A7306164011

for the PDU can you link me on what you think would be most beneficial for my setup?

What would be the exact one best model for what I'm doing ?


Also after talking to these guys I think I'll have to change my plan I'm just going to screw the house up, more complicated, more expensive, etc when I could just drop a shed on my property and then have free reign to do everything that I want to do on there

So.  . what size shed do i need here my plot I can work with is 15x20

I'm thinking 12x16 would would be plenty, 14x18 maybe max?

[VoskCoin]

So revised plan . . .

I have ~13 ft width and 20 ft length asphalt patch

Drop 12x12 or so shed on said patch

Run fans <---exhaust [SHED] <--- intake / electric run, secure facility and done? 12x12 should give me ample room to run enough rigs to max out my power -- agreed? Thoughts / input?

Can anyone give me links to exact fans that would work for this setup, 3000 CFM?

Thank you for everyone helping here

I don't see any reason to not copy it exactly. I would try to speak with him about it though, I'm sure he has already found ways to improve it.

Those PDU's you posted would work fine. Just be aware of the number of outlets, and amp limit of the PDUs.

Guys what fans should I be using? Simply slap a large (but how large?) intake fan on the right side then blow through and a large (is 3000 CFM the right size?) exhaust fan on the left. Is it this simple?

2 exhaust fans high




I would argue in a 12 by 12 shed

using   this to feed in the air

cut low holes on one side of the shed.    say  6  and use the vents above.  inside the shed do  a bend up to cut down dust

http://www.homedepot.com/p/Speedi-Products-5-in-B-Vent-90-Degree-Round-Adjustable-Elbow-BV-A90-05/203530661

Shed is a great idea. With 3000cfm fan pulling from inside your house your home A/C would never keep up anyway and would run constantly, taking all your mining rewards. The size(mining are) isnt that important...getting the heat out quickly is. I hope to have my shed delivered in the next two weeks. I still have to get underground power over there but shouldnt be much of an issue. Im going with a 36" 5000cfm fan. I will be getting a 12x26 shed and dividing it off only to use a smaller portion for my mining room( approx 10x12 area). The rest will be storage. If you havent got yours situated by then maybe i will have more advice at that time. I think the shed is the proper way to go.

[WarrEagle]

5 Rigs or are you going to grow. You can run 5 rigs on a 50 Amp 230V circuit easily with room for about 4 more. You have plenty of open slots for expansion. I would definitely recommend a PDU or 2 to handle the PSU connections from the rigs and run them at 230/240V since the PSU's are more efficient. It's only like 2-3% but worth it.

You are running older cards and will want to exhaust the heat generated by those 280X to the outside. Phil has a good idea, I did something different and bought 2 - 30 inch barrel fans and opened the garage side door and stapled a screen over the frame. Built a tarp canopy out of PVC pipe and a tarp to keep out the rain. Placed the fans on a wire shelf and had them facing so that they pulled air across the rigs in front of them. Had to keep my garage door open about 4 inches to let fresh outside ambient air in. In August in Florida my cards all stayed under 75 degrees Celsius.

I ran 5 rigs for several months last summer. I only have 100 amp service, and was tripping breakers a lot, especially since we have a Volt with a level 2 charger. I had to explain to my wife not to plug in her car till after we finished cooking dinner. Stove + Volt + A/C + Hot water tank + Rigs overloaded my mains.

Good luck with the build and post some pics when its running!

How large was your garage and how many cards were you running? Those are some pretty good results in FL!

[WarrEagle]

I ran 30 cards total, 5 rigs, 6 cards each. All 380's 600 MH/s mining ETH. I was finding a 1.5 blocks a day when I first started, then a block a day as more people joined the circus.

Power bill was $850 to $900

Oh, now I look stupid. The PDUMV30HV. I chose this over one of the smaller cheaper options because my setup specifically needed two separate monitored circuits, one for the top half and one for the bottom half of my rack. For a small room as long as you're going with a limited number of power supplies one of the smaller PDUs should work just fine.

Okay so my question to you and everyone else is specifically on these fans,

I'm going to get a dormer style shed unless anyone recommends against that?

With the fans, should I just mount a massive fan blowing up and out / attic style fan like suggested?

Sorry for all the questions, trying to make sure I knock this out once & right.

Also I'm thinking two fans would make more sense because then if one goes down I can still limp along, also while my setup is still growing I could simply use one fan?

Definitely keep me posted, even just update your journey in this thread if you'd like!

Why did you choose a 5000cfm fan?

for 20-30 rigs with 6x cards each in a 12x12 how much fan am I going to need?

What's the best setup for the fan? blow through intake on right exhaust on left side, or intake vents on both left and right with 2 big attic exhaust fans in the middle? Just want to build the most efficient setup possible you know?
