I've got lots of questions about this and I don't even know where to start.
Usually I build bitcoin mining farms and get % every month for just paying attention to them.
Couple weeks ago I got the order to maintain the ETH farm where already are installed 60+ GPUs (r9 380, r9 470x 480x) and they want to expand, maybe 100-150+ GPUs.
I don't know about profitability, because after Litecoins I simply switched to BTC.
Honestly I really don't care if they will loose all their money invested in GPUs and ETH itself, but can I give them some kind of advice maybe?
Until then I have some technical questions (and I don't know ask them here or somewhere else but I'll still ask):
What is the best OS to to install on SSDs? (ATM they have mixed versions of windows). I tried to research but found nothing. Will ubuntu do it's job or win7 professional is better? I didn' liked the EthOS..
What is the best software or any technique to monitor (not control) all the rigs at once? Remotely or locally?
that's it I guess for now (:
