Well, I am not sure this solution is easily feasible (top open ALL the miners...) and that everybody will be OK with that.
I have 30 Dragon and except since yesterday, it works fine (I have one down). I choose the Professional hosting.
I am happy with the service, even if it runs down sometime. It is still better to what I can have at home and better in term of price/service to other hosting I try. I did my maths and since august, I loose something like 0.5BTC in downtime. I am good with that considering I have 30 miners at roughly 30kW...
I just checked and the simple dc looks down right now...
and my miner went down.
A suggestion if you have 400 miners and you are popping the circuits.
run the 400 miners for now with each with 1 board pulled and see if they can be stable.
better that then nothing.
A dragon miner has 4 boards disconnect 1 board on every miner. will all get 750-800 gh for each miner. and you do not blow/trip the power off
I run into the heat issues on a small scale.
I had 13 pcs with 24 gpus pulling 6k I had to turn some off or trip circuits.
