Topic: Need help on S9 first farm setup - page 2. (Read 1667 times)

dpends on what wall outlet ur electrician installs , honestly u can wire up a standard 110v outlet to be 220 ( this is what i do , i just paint the ouutlest red so i know they arent 110)
but this isnt up to code i belive , but in doing this u can use the std plug cord without having to change the end.

honestly as long as ur not color blind , replacing the end of the cord is very very simple , infact i can bring home a cord from my data center and take pictures of how to swap the end if u like

if not dust free just be sure to blow the miners out ( with them powered off ) with some compressed air , i clean my miners  once every 1-2 weeks

how large is the warehouse and what are the normal temps inside the building?
if its a large area and temps are fairly cool u shouldnt have to worry about extra cooling with only a few machines
now if its a small space then u may have to do something

my miners are in a 3,000 sqft datacenter , and i need no aditional cooling unless ambient air temps are above 85* , in the fall and winter my miners actually heat the building to a comfortable level , infact last year i had issues with my miners being way to cold i.e 14-17*c

also install the miners low to the floor , u dont want them on a shelf 8 ft off the ground as heat rises as we all know

Dust-free would help, since heatsinks can get clogged. As long as you kick the dust out of them regularly (compressed air and whatnot) they can survive about anything.

Yep, the S9 has ethernet built in. You'll hook 'em all to a network switch. They are also set up for DHCP, which means they don't have preset IP addresses so your router will have to handle that. Most do automatically, but it's something to note just in case.

Miners don't require much bandwidth at all. The most important thing is going to be latency, so you'll want a connection with short ping times to the pools you want to use. Speed's secondary as long as it's reliable. You can run a whole farm off a 1mbit connection as long as it's low-latency. And if you're worried about it, run a local proxy to the pool; that will convolve all your miner connections into one pool connection and use even less data transfer.

Thanks for your replies.  I am in the US.

Because this is new to me, I wanted to start out small.  As things goes well, I do plan to purchase a more.  So I do want to plan ahead. 

@sidekick, I usually plan things out before taking action.  This is an exception.

For ventilation, I was thinking about having an hvac guy cut a hole in the ceiling with a fan sucking the air out.  Is this a good idea?

As far a network goes, I assume I would connect all of the S9s to a 40 port switch or something?

What internet speed does the S9 require?

The S9s doesn't need to be in an absolutely dust-free environment to operate right?  Just normal environment works fine?

@jstew,  "no need for a special cord , just take the cord that comoes with the psu and cut the wall end off and get the end for the outlet u are using from the hardware store and put it on the power cable , green to the ground pin , and black and white goto the other 2 pins  for 220 as long as ur in the usa. being as u said u have 110 or 220 i take it u are"  I'm really hesitant/dare i say afraid, when it comes to electrical things. I don't know if I am competent enough to cut cords and splice them together.  Is there an already made cord that I can buy from amazon/ebay or something?

^^^ sidehack also sells server psus breakouts and stuff

Just throwing this out there, but these are questions it's usually wise to answer before laying down four figures on equipment.

220V is a better option for loads in this power range. You can run three S9 to a 20-amp circuit.

I'd recommend server PSUs over consumer ATX supplies. Comparable efficiency, lower cost, modularity and easy to replace.

You'll want to keep the ambient temperature below 90F, preferably below 80F. These miners are fine to run 24/7.

Remote access will give you a lot of control, but occasionally they might lock up or a fan will kick out or a PSU will trip that'll require on-site attention.

So, pretty much what he said.

my advise is buy a 2880w psu package from finsky or one of the other reputable members 2880w psu will run 2x s9's for about the same price as that evga psu and since its in a warehouse i doubt noise is an issue

there is also the dps 4k setup which will power 3x s9's from one psu and will fill up a 20 amp 220/240 line

the server psus require 220v so just have ur electrictian run a 20 amp 220v line to were the miner will be , no need for a special cord , just take the cord that comoes with the psu and cut the wall end off and get the end for the outlet u are using from the hardware store and put it on the power cable , green to the ground pin , and black and white goto the other 2 pins  for 220 as long as ur in the usa. being as u said u have 110 or 220 i take it u are


using 220 over 110 has 2 advantages , most psus are more eff at 220 and u can pull more power over the same line

1300w on 110v is 11.81 amps  u could not run 2x s9's on a single 20 amp 110v line
1300w on 220v is 5.9 amp u could run 3 s9 on a single 20 amp 220v line


so if u plan on more miners theres a cost savings cause u dont need to run as many lines as well

yes they can run 24/7 , for monitoring u can use soemthing like a pc with teamviewer on it at the warehouse that u can connect to from home to check on the miners from there webpages or just keeps tabs on them from the mining pools stats page

there are other more elegant soulutions but probably not needed in ur case for a single/couple miners

Hi,

I'm a new miner.  I just bought some S9s.  I'm looking to start a new farm in my existing warehouse and I'm not sure exactly what I'll need.  I searched for a guide on how to setup farm but didn't really see any.  So I'm asking the more experience miners for advices.

My current warehouse is just for storage of non-computer items.  So I need to modify the electrical panel to accommodate the power hungry S9s.  Do you know what I'll need to tell the electrician so he'll know what modifications to make?

What thoughts you have on how best to ventilate the enclosed warehouse?

I know the S9s doesn't come with a power supply and a power cord.  I'm looking at EVGA SuperNOVA 1600 G2 Power Supply.  What do you think?

I heard that the 220? volt is more efficient that the 110?  Do I simply buy a 220v power cord and plug it into the EVGA power supply?

What power cord do you suggests?

Let me know what else I need to consider in planning out this farm.


Misc Questions:

How are the S9s connected so that you can monitor all of them?

Is it ok/wise/safe to have the S9s run 24/7? 

Does the farm need constant attention where I need to be there physically everyday to make everything is ok or can I monitor it remotely?

Thanks!
