Hey everyone,
During setting up our mining farm we were faced with lots technicals problems.
Here we wanna share some experience to prevent others from this problems.
1. Electricity sourceYou are lucky if your farm already connected to electricity source, if no ensure, that distance between
switchboard and your junction box is not very long.
By this way you can prevent electricity leak and cut expenses for wires.
For instance, we were bought quite safe and thick wire with price ~82$ per meter (505rmb).
Of course it should be 380 Volt
2. Junction electricity box and wiresWires from junction box to miners
When we established it we were bought fake wires with not enough thick of cross section. We detected it, when checked temperature of wires. God bless, we have thermographic camera. So, wires temperature were ~75C degrees and we've got understanding something went wrong.
To prevent inflammation, we were forced to replace wires immediately. After replacing cables average hashrate jumped more than 5%.
3. Cooling and ventilationWe decided to use air cooling system this time.
When you establish big mining farm you have to think about miners displacement.
From one side you have to have incoming cold air flow from outside.
From other side fans should to convey hot air outside.
We decided to install huge cooling fans into the window:
Tipsa) ensure how is blowing air flows.
b) ensure, that between sections have no large splits.
c) remove micro disperse dust from equipment. Try to keep the room more or less cleaned.
4. Miners displacementAs I wrote before, you have to think about miners displacement.
We decided to mount its to server racks. Not sure, it was a best idea, but its easy to manage.
5. Internet connectionFor each 9 miners we connected TP-LINK with 16 ports.
To connect all racks together we used CISCO with 48 ports.
Tipsa)Install the fastest internet connection as you able.
a)Use good quality connectors.
